Characteristics of Diesel Flow

Diesel is a kind of light petroleum, which belongs to the fuel of diesel engine. The use of high-speed diesel engines on cars is more fuel-efficient than gasoline engines.

Diesel demand is growing faster than gasoline. Diesel engines have higher thermal efficiency and higher power than gasoline engines. The fuel consumption per unit is low and relatively economical, so the application is increasing day by day. In many occasions, it needs to be measured.

For oil tanker or diesel storage tank pipeline transportation, it is more suitable to choose a flowmeter with higher measurement accuracy. Because it is not only convenient for trade settlement, but also high precision. The measurement is accurate and can be used for a long time.

According to the role of diesel: the use can be divided into marine diesel engine, locomotive diesel engine, automobile diesel engine, power generation diesel engine, agricultural diesel engine, construction machinery diesel engine, etc.

Diesel Fuel: Diesel fuel is primarily diesel. Light diesel oil is usually used for high-speed diesel engines. Light diesel or heavy diesel for medium and low speed diesel engines.

Mechanical Diesel Flow Meter Working Principle

Oval gear flow meters are our most commonly used Mechanical Diesel Flow Meters.

The oval gear flowmeter is composed of a metering box and a pair of elliptical gears installed in the metering box, and the upper and lower cover plates form a sealed crescent-shaped cavity (due to the rotation of the gear, it is not sealed) as the calculation unit of a displacement .

The flow meter is mainly composed of a housing, a counter, an elliptical gear, and a coupling (magnetic coupling and axial coupling), etc. As shown in the figure.

1.Counter 2. Transmitter

3. Accuracy adjuster (used above DN50)

4. Sealed coupling

5. Front cover 6. Cover plate

7. Oval gear 8. Shell

9. Rear cover

When the measured liquid enters the flowmeter through the pipeline, the pressure difference generated at the inlet and outlet pushes a pair of gears to continuously rotate, and the liquid measured by the crescent-shaped cavity is continuously transported to the outlet. The product of four times the secondary displacement is the total amount of the measured liquid flow.

The elliptical gear generates a torque to make it rotate under the action of the pressure difference △p of the measured medium.

The rotor 1 and the rotor 2 are alternately driven by one to rotate the other. There are two magnets on each rotor as signal generating elements. There is a magnetic signal detecting element at the center of the two axes at the bottom of the cavity. Whenever the magnet turns to the detecting element, the sensor counts as a pulse.

Each pulse corresponds to a certain amount of medium discharge F, F=XXml/p, so the volume flow Qm per unit time can be obtained: Qm=F*H, F is the amount of medium removed by each pulse; H pulse per unit time number.

Take an oval gear flowmeter as an example. Under the action of fluid flow, a pressure difference is formed between the inlet and outlet of the instrument. A pair of oval gears are constantly rotating on the shaft. The cavity between its gears is filled with liquid.

As the rotation is discharged, the flow rate of the liquid flowing through the meter can be known by measuring the number of revolutions of the oval gear.
Assume that the volume of the oval gear discharged by one rotation of the oval gear is Q. The number of rotations of the oval gear per unit time is N. Then the volume of liquid that flows during this time is NQ.

If we choose an oval gear flowmeter made of stainless steel, it can also be applied to the measurement of many chemical liquids.

Commonly used fuel flowmeters include turbine flowmeters, circular gear flowmeters, oval gear flowmeters, mass flowmeters, etc.

A high pressure orifice plate flowmeter is a device used to measure the flow of fluids through a pipe. It consists of a plate with an opening in the middle, through which the fluid flows. The plate is placed in the path of the fluid stream and the pressure drop across the plate is measured. This pressure drop is then used to calculate the flow rate. High pressure orifice plates are used in applications where the fluid being measured is under high pressure, such as in steam, oil and gas pipelines.

Applicable measured media is very wide, can be used for almost all gases, steam and liquid flow measurement.
Use pressure up to 32MPa, also can be used for negative pressure.

Measuring Flow with Pressure Sensors

Differential pressure sensors have been widely used to measure the flow of incompressible liquids. A very common method is to measure the pressure drop across the orifice in the pipe and calculate the flow.

An orifice plate is simply a plate that fits in a pipe (usually between flanges) with a hole of known size in its center. As the fluid flows through the orifice, a pressure drop develops across the orifice plate from the upstream side to the downstream side. This pressure drop is proportional to flow, and the sensor signal can be used to calculate flow in engineering units.

The upstream side of the orifice will have higher pressure and will be connected to the + port of the pressure sensor through a three-valve manifold. The downstream side of the orifice is similarly connected to the -port of the pressure sensor. The three-valve manifold is used to protect the pressure sensor from overpressure when the pressure sensor is installed into the work pipeline.

Calculations to determine flow from pressure drop are derived from fairly simple physical equations. However, there are many variables, each with its own engineering unit. These include: hole geometry, pipe size, fluid viscosity and fluid density. Given the number of terms and the conversion factors involved in each variable, the calculation can be quite involved.

Fortunately, there are many online calculators that allow you to simply enter variables in any engineering units that are convenient for you, and then calculate the flow rate for any given pressure drop across the orifice.

How to install the pressure sensor when measuring the flow pipeline?

When detecting the gas and fluid pressure in the pipeline, the pressure guiding pipe is connected with a vertical tee before entering the pressure sensor. The sampling gas enters from the upper part of the tee. The lower part of the tee is connected to a water collecting irrigation, and the horizontal interface of the tee enters the pressure sensor .

The pressure sensor is installed horizontally. The sampling pressure pipe is connected to the upper part of the pressure sensor detection diaphragm. The lower part of the detection diaphragm has its own discharge bolt.

When there is liquid entering the pressure guiding pipe, a large part will be collected in the water collecting irrigation. A small amount of liquid entering the pressure sensor detection diaphragm can be discharged by the discharge bolt of the pressure sensor.

When measuring fluid pressure, the pressure of the main fluid is taken as the measurement object. Therefore, when the pressure sensor measures the gas pressure in the pipeline, in order to prevent the liquid in it from entering the sampling pressure pipe. The sampling point is 45° above the horizontal plane of the center of the pipeline.

When measuring the liquid pressure of the pipeline, in order to prevent the gas in it from entering the sampling pressure guiding tube, the sampling point is 45° below the horizontal plane of the center of the pipeline. Read more about: Shop 101: Key Factors In Selecting A Pipe Flow Meter

Even so, it is inevitable that different phases of fluid will enter the sampling impulse pipe. There are different requirements for the installation and configuration of the pressure sensor impulse pipe.

The water collecting tank or gas collecting tank installed on the pressure guiding pipe is equipped with an inlet valve and a discharge valve. During normal testing, the inlet valve is opened and the discharge valve is closed. When it is necessary to discharge, first close the inlet valve, and then open the discharge valve. . This discharge method will always have a bit of out-of-phase fluid remaining in the water or gas header, but it will not affect the pressure sensor detection accuracy.

Fluids include both gaseous fluids and liquid fluids. The density and pressure of gaseous fluids are lower than that of liquid fluids. So in pipeline fluids, the gaseous fluid is always above the liquid fluid. This is the basic characteristic of vapor-liquid two-phase fluid.

If an insertion flowmeter is to be selected for a wastewater pipeline, an insertion electromagnetic flowmeter must be the first choice.

The Insertion wastewater flowmeter can be widely used to measure the flow of conductive fluids in tap water, steel, petroleum, chemical industry, electric power, industry, water conservancy, water administration and water resources. It can also measure corrosive conductive liquids such as acids, alkalis, and salts.

The Insertion sewage flowmeter is mainly composed of a measuring head (or measuring tube), an excitation system, an insertion rod, a junction box, a mounting base, and a sealing and positioning mechanism.

Measuring head (or measuring tube): The measuring head (measuring tube) is located at the particle point of the measured flow velocity in the pipeline, and is used to detect the flow velocity at this point. A measuring head (or measuring tube) is a tip or conduit made of insulating material on which a pair of electrodes is mounted. Except for the electrode tip or the inner wall of the measuring tube, other parts are insulated from the fluid to be measured.

Excitation system: The function of the excitation system is to generate a working magnetic field. It consists of an excitation coil and an iron core. It is insulating sealed into the insertion rod.

Insert rod: Made of stainless steel material. The measuring head and the measuring tube are fixed in the insertion rod. The excitation lead and electrode lead are sealed with the measured medium and connected to the junction box through the insertion rod. A direction indicator is welded on the insertion rod to ensure that the working magnetic field, the flow rate and the electrode connection are perpendicular to each other during installation, which meets the requirements of Faraday’s law of electromagnetic induction.

Junction Box: The junction box is located on the top of the sensor. The terminals in the junction box connect the sensor and the converter to each other.

Mounting base: The mounting base is welded on the pipeline under test, used to connect with the mounting ball valve and insert the part of the sewage flowmeter sensor.

Sealing mechanism: It consists of a compression thread seat made of stainless steel, a compression nut, a rubber washer and a positioning screw. It is used to seal and insert the sewage sensor, so that it can avoid a certain working pressure.

insertion flow meter for air/compressed air

If you choose an insertion flowmeter for an air line, or a compressed air line. Then the insertion thermal mass flow meter can be said to be the first choice.

Because, the insertion thermal mass flow meter has obvious advantages:

Wide range ratio 1000:1; large diameter, low flow rate, negligible pressure loss;
Direct measurement of mass flow without temperature and pressure compensation;
Very sensitive measurement of low flow rates;
Easy to design and select, easy to install and use;
Suitable for all kinds of single or mixed gas flow measurement.

If you need to measure high temperature air, or high temperature compressed air. Then another type of flow meter may need to be selected. Such as high temperature Annubar flowmeter.

The installation requirements of various insertion flowmeters vary. Here is a brief introduction to the standard installation of plug-in electromagnetic flowmeters:

The arrangement of instruments on the pipeline should be far away from the valve. Maintain a 10-diameter upstream intermediate pipe section and a 5-diameter downstream straight pipe section.
The on-site power supply needs to match the instrument power supply, generally a 24V rectifier. If there is no external power supply for the field measurement, an external power supply meter will be connected.
Pay attention to the flow direction of the measured liquid on the inner wall of the pipe. If the installation is reversed, the measured liquid will show a negative value.
The installation site should be cool and rain-proof. If it is often rained or immersed in water, the protection grade IP68 product should be selected.
The fluid flow in the pipeline should not be stopped if the process requires it. Media should not spill. A ball valve needs to be installed.

Different digital flow sensors include turbine, thermal mass, electromagnetic, ultrasonic, orifice plate, venturi. The different designs of the flowmeters have a variety of applications. With 4-20ma, RS485, or other output.

Then they all work differently. However, they can convert the flow signal into a digital display, or pulse, or 4-20mA signal.

Crude Oil Flow Meter

Posted on September 12, 2022 by KimGuo11

Crude Oil Flow Meter refers to a type of flow meter that can accurately monitor and measure the flow of crude oil. Crude oil is an industrial raw material with complex physical and chemical properties. In the process of production, storage, transportation and trade, it is greatly affected by factors such as temperature, pressure and environment. Storage, transportation and handover not in accordance with standard specifications will lead to increased measurement errors and affect product quality.

Therefore, the flow measurement of crude oil has always been the focus and difficulty of the oil and gas extraction industry.

After years of service experience, Sino-Inst offers multiple crude oil flow meters. Including mass flowmeters, positive displacement flowmeters, turbine flowmeters, etc.

RFQ Flow Meters

Featured crude oil flow meters

types of crude oil flow meters

In terms of the medium to be measured, the crude oil containing impurities needs flow measurement, and the flow measurement of the working conditions with impurities itself is a big problem. Choosing the right crude oil flow meter is even harder.

Based on years of service experience, the following 7 type flowmeters are the types of flowmeters that we believe can effectively measure the flow of crude oil.

In order to realize the accurate measurement of crude oil production, real-time automatic measurement of incoming crude oil quality is the fundamental method.

The mass flow meter has high precision, easy to use and easy maintenance, and long service life. Crude oil production can be directly measured. It is supplemented by a computer real-time monitoring and measurement software system based on it. and utilize network resources. It can also realize remote real-time monitoring of the flowmeter.

The mass flow meter measures the crude oil quality, crude oil volume, water content, temperature and other data on the liquid pipeline in real time. It is displayed on the metering post through the on-site display instrument.

At the same time, the on-site display instrument transmits the relevant data signals to the on-site data storage and remote transmission equipment (industrial computer).

For the crude oil mass flowmeter used for single well measurement, due to the presence of some chemical substances in the measured medium, the flowmeter will cause scaling on the wall of the mass flowmeter measurement pipe after a period of operation.

The composition of scale is very complex, mainly composed of asphalt, wax, sulfide, carbide, etc.
The scale on the inner wall of the measuring tube of the flowmeter will affect the accuracy of mass flow and density measurement, thereby affecting the normal measurement performance of the mass flowmeter and causing a relatively large measurement error.

To ensure the normal use of the mass flowmeter, the flowmeter must be cleaned and descaled regularly. Then re-calibrate to determine the new configuration parameters of the instrument before it can be put into use again.

It is well known that the oval gear flowmeter is especially suitable for the flow measurement of the medium with high viscosity such as heavy oil, polyvinyl alcohol, resin, etc. The oval gear flowmeter has high measurement accuracy. It is suitable for the measurement of high viscosity medium flow (generally the viscosity of the liquid to be measured is 2-3000Mpa.s).

But not suitable for fluids containing solid particles. If the measured liquid medium contains gas, it will also cause measurement errors.

Usually, the accuracy of the oval gear flowmeter can reach 0.5, which is a relatively accurate flow meter.

However, if the flow rate of the measured medium is too small, the influence of the leakage error of the oval gear flowmeter will be prominent. Sufficient measurement accuracy can no longer be guaranteed.

The working principle of the dual rotor flowmeter is done in the metering chamber. It is directly meshed by a pair of special toothed helical rotors. No relative slippage.

Although the pressure of the liquid acting on the two rotors is different. However, a pair of synchronizing gears installed on the two rotors always maintains an appropriate gap between the two rotors, ensuring that the rotors can rotate smoothly and synchronously.

Several cavities with known volumes are formed between the rotor and the casing. Under the action of the measured medium, the micro-pressure difference between the inlet and outlet of the flowmeter drives the two helical rotors to rotate in opposite directions. The helical rotor can output 8 times the volume of the cavity per revolution.

Therefore, the number of revolutions of the rotor is proportional to the cumulative flow of the fluid. The rotational speed of the rotor is proportional to the instantaneous flow rate of the fluid. Therefore, the number of revolutions of the rotor can be transmitted to the counter through the transmission gear system to directly display the liquid flow.

At the same time, it can also be converted into an electrical pulse signal by adding an electromechanical conversion device. Then pass to the secondary instrument or computer for remote display and control.

The repeatability and stability of the dual-rotor flowmeter are in a linear state, which meets the requirements of crude oil export.

The dual-rotor flowmeter has been popularized and applied in various crude oil gathering and transportation stations and external transportation measurement rooms in oilfields. Undertook the measurement task of 4400t/d crude oil export, and its measurement data has been recognized by both sides of the trade.

The target flowmeter adopts the latest force sensor as the measurement and sensitive transmission element. At the same time, the latest digital technology and microelectronic technology are applied. It is an intelligent flowmeter suitable for the measurement of fluids and gases with high viscosity, low Reynolds number and tiny particles.

The use of force sensors is the key to the true realization of high precision and high stability of this product.

The target flowmeter not only has the characteristics of traditional orifice plate, vortex flowmeter and other flowmeters without moving parts. At the same time, it has measurement accuracy comparable to that of positive displacement flowmeters. Coupled with its unique anti-interference, anti-impurity performance.

In addition to the target flowmeter can replace the conventional flowmeter and conventional fluid flow measurement. Especially in high viscosity, easy blocking, high temperature, high pressure, strong corrosion and other difficult flow measurement conditions have good application value.

At present, it has been widely used in flow measurement in various fields such as steel, oil, natural gas, electric power, papermaking, chemical industry, energy, food, environmental protection and so on.

Therefore, the target flowmeter is a good choice for measuring high viscosity crude oil.

As long as the Reynolds number fits within the measuring range of the target flowmeter, it can be measured. Viscosity changes do not need to be considered. In addition, it can be equipped with a temperature sensor for density correction, which can ensure good measurement accuracy.

Turbine flowmeters can measure media such as special oils.

There are many varieties of oil, edible oil, peanut oil, diesel oil, gasoline, etc. are all oils. Turbine flowmeters measure the flow of liquids. However, it is not recommended to use it for measurement of too viscous liquids. Because the turbine flowmeter uses the principle of impeller rotation to measure the flow, and too viscous liquid will affect the rotation of the impeller.

Turbine flow meters can measure low temperature and non-viscous special oil. If the user’s working condition is measured on site, it is a special type of high temperature type oil. Nor can it be measured with a turbine flowmeter. The turbine flowmeter can only measure the working temperature when the ambient temperature on site is 120℃.

Therefore, the user chooses the turbine flowmeter to measure crude oil, and needs to choose according to the actual working conditions.

Magnetic Flow Meter is a flow meter that measures the flow of conductive fluids. Abbreviated as EMF, also called Electromagnetic flowmeters. It is a kind of Volumetric flow meter. A magnetic flow meter measures the velocity of conductive liquids moving through a pipe or conduit. In the wastewater treatment industry, Magnetic Flow Meter is the best flow meter choice.

The split-type electromagnetic flowmeter can also measure high-viscosity fluids. Based on the principle of electromagnetic flowmeter and other factors, this is theoretically true, but it also depends on the specific site.

In addition to measuring the flow of general conductive liquids, the split-type electromagnetic flowmeter can also measure liquid-solid two-phase flow, high-viscosity liquid flow and volume flow of salt, strong acid, and strong alkali liquids.

The differential pressure flow meter is measured by the working principle that there is a certain relationship between the pressure difference and the flow rate when the medium fluid flows through the throttling device. Differential pressure (DP) flow meters are the most widely used form of flow measurement products today. Including: integrated orifice flowmeter, average velocity tube flowmeter, venturi tube, wedge flowmeter, underwater flowmeter, orifice plate, orifice carrier assembly, nozzle flowmeter.

Differential pressure flowmeters always have unexpected advantages in measuring complex working conditions.

For example:
Wedge throttling device is a new type of throttling device developed by our company. , Its special structure, non-clogging, solid structure, long life, can be used to measure liquid, gas and steam.

It is especially suitable for flow measurement of fluids with low flow rate, high viscosity, dust or solid particles. Such as measuring crude oil, fuel oil, residual oil, coal tar, waste water, carbon black solution and other fluids.

Summary of Crude Oil Flow Measurement Options

Flowmeters are the most commonly used instruments in oil exploration enterprises. The selection of flowmeters used in many production sites in oil fields is not reasonable, and some have installation errors, resulting in excessive measurement errors, and some cannot meet the needs of production or crude oil transfer measurement.

Many forms of flowmeters can measure crude oil, but when choosing a model based on experience and simply considering the purchase cost, you may lose the opportunity to choose the most suitable meter.

For example, the flow range of the instrument does not match the actual flow, and the instrument with high precision is selected for places with low measurement requirements.

It can be seen that the correct selection and use of flow meters is not an easy task. To choose a crude oil flowmeter correctly and efficiently. The following five factors must be considered, namely: performance requirements, physical properties of crude oil, installation requirements, environmental conditions and costs.

Read more about: Flow Meter Selection Guide

When selecting a flowmeter, the performance requirements to consider include: instantaneous flow, cumulative flow, degree, repeatability, linearity, flow range and range, pressure loss, output signal characteristics and response time.

Different measurement purposes have different options in terms of flowmeter performance. Such as crude oil trade settlement measurement requirements are relatively high.

Continuous measurement process control usually requires good reliability and repeatability. Sometimes a wide range of degrees is also required, and the requirements for measurement degrees should be placed in a secondary position.

The oilfield production site does not require the flowmeter to have too high accuracy, but it has good adaptability to the physical properties and working conditions of crude oil.

The operation of the crude oil flowmeter is affected by factors such as crude oil temperature, oil delivery pressure, crude oil density, crude oil viscosity, and flow rate.

The physical properties of crude oil will change to some extent with the changes of temperature and pressure.

When crude oil is measured by a flow meter, the volume of crude oil will be affected by changes in temperature, pressure, viscosity and other factors.

Among them, temperature is one of the most influential parameters in flow meter measurement. Changes in temperature can cause changes in a series of parameters, which change the volume, density, viscosity of the crude oil and the gap between the flowmeter housing and internal components, thus resulting in changes in leakage flow.

If the temperature is lowered, the paraffin and coke in the crude oil adhere to the inner wall of the shell and parts. This changes the volume of the metering chamber of the flowmeter. It directly affects the measurement accuracy of the flowmeter.

Flow meters of different principles have very different installation requirements. For example, differential pressure and turbine flowmeters require a long upstream straight pipe section, and some flowmeters do not have this requirement or have lower requirements. Some flowmeters need to consider the installation location and medium flow direction, maintenance space, installation direction, etc.

The measurement performance of the flowmeter is greatly affected by the installation conditions, and the reason for the large error of the flowmeter. Part of it is caused by poor installation.

Factors to be considered in the installation are: the installation direction of the flowmeter, the flow direction of the crude oil, the upstream and downstream straight pipe sections, the valve position, vibration, electromagnetic interference and maintenance space.

The ambient conditions of the meter and its expected changes, including ambient temperature, humidity, safety, and electrical interference, should be considered in the flowmeter selection process. The electronics of the meter and some of the meter’s flow sensing portion are affected by changes in ambient temperature.

For example, the size of the flow meter housing changes, and the heat transfer through the meter housing changes the density and viscosity of the fluid. When affecting the display meter electronics, it will degrade measurement performance. Sometimes the conversion display part and the flow sensor are installed in different places to ensure that the electronic components are not affected by temperature.

High humidity will accelerate atmospheric corrosion and electrolytic corrosion and reduce electrical insulation, and low humidity is prone to static electricity. These can have an effect on the circuit part of the flowmeter and sometimes even cause a malfunction.

In terms of economy, it is not comprehensive to consider only the purchase cost of the instrument, and other costs should also be considered. Such as accessories purchase costs, installation costs, maintenance and flow meter verification costs, operating costs and spare parts costs. Trade settlement measurement should also compare the economic losses caused by measurement errors.

The operating cost of the flowmeter is mainly the energy consumption during operation. Some flowmeters are powered by dry batteries, and the cost of battery consumption is also considerable. Pumping costs are a hidden cost that is often overlooked.

The maintenance cost is the cost required to maintain the normal operation of the measurement system after the instrument is installed and put into use, mainly including maintenance labor and spare parts. Instruments with moving parts generally require more maintenance work, such as regular replacement of wear-resistant bearings, shafts, rotors, transmission gears, etc.

The selection of crude oil flowmeter should comprehensively consider the five factors of instrument performance, fluid characteristics, installation conditions, environmental conditions and economy.

Encounter the phenomenon that the physical properties of crude oil, especially the viscosity-temperature characteristics, are not very clear. Special units should be invited to do a complete set of crude oil tests and make a physical property report.

Consult with the flowmeter manufacturer or technical department about the adaptability of various flowmeters and the influence of physical property changes on the performance of the flowmeter. Choose a flowmeter that meets your needs.

Will mechanical water meters be replaced by new smart water meters? Then we have to see which of their respective performance can better meet the market demand.

Let’s take the current popular LORA wireless remote water meter as an example to compare it with ordinary mechanical water meters.

The most prominent drawback of ordinary mechanical water meters is its meter reading method, and the impact of this drawback is becoming increasingly prominent.

In our inherent thinking, it is a very common and normal thing for meter readers to go door-to-door to read meters. However, under the impact of technologies such as the Internet of Things, the efficiency of door-to-door meter reading has been questioned.

The LORA wireless remote water meter developed using new technology is a meter reading command issued by the meter reader through the remote meter reading system. After the LORA module on the wireless remote water meter receives the meter reading command, it will The data is uploaded to the server. The meter reader can read the water meter data. This avoids the high cost and low efficiency of manual meter reading and the nuisance problems caused by household meter reading.

No matter what kind of water meter and what kind of function it has, they are all born to serve people’s lives. Whoever can provide more convenience and higher efficiency will be pushed to the stage of history.

Factors affecting the accuracy of petroleum flow meters

(1) Instrument accuracy

During the production of the flow meter, due to rough parts, assembly accuracy and wear, etc., the accuracy of the flow meter itself is not high or the accuracy is reduced, so that the quantity of petroleum products sent (paid) is inaccurate. Therefore, when selecting a flowmeter, one with higher accuracy should be selected. At present, the accuracy of the working flowmeter is required to be ±0.5% in China, and the periodic verification should be carried out according to the regulations in use.

(2) Installation process

Although the accuracy of the flowmeter is high, due to improper or unreasonable installation process, the flowmeter will produce systematic errors. If there is not enough straight pipe section in front of the flowmeter (generally the straight pipe section should not be less than five times the diameter of the oil pipeline used), eddy current will occur, and the elbow in the pipeline will increase the flow resistance for a long time, which cannot guarantee the working pressure of the flowmeter. It can cause errors in the indication value of the flowmeter.

Extended reading: Crude oil measurement, 80G radar level meter should be your first choice!

(3) Medium

The medium used for the factory calibration indication value of the flowmeter is different from the medium at work, and the indication value reflected by the flowmeter is also different. For example, water is used as the medium during calibration, but it is used in various petroleum product media during work, so there will be errors, mainly due to the different viscosity of the medium. Therefore, it is required that the medium used for calibrating the indication value of the flowmeter should be consistent with the working medium, so as to eliminate the error caused by this.

(4) Temperature

The flowmeter cannot display the true value of the output (payment) amount due to accidental errors caused by temperature instability during the work start to end. Therefore, it is required that the flowmeter should keep the temperature as consistent as possible during the oil delivery process.

(5) Differential pressure and flow rate

The use of the flowmeter should be within the specified pressure differential range to ensure accuracy. Because the pressure is high and the flow rate is fast, the flow rate is also large, and vice versa. If the flowmeter cannot maintain the consistency of the pressure difference between the front and rear during the oil delivery process, and it is higher or lower than the working pressure difference range of the instrument, it will affect the accuracy of its output (payment) volume.

Extended Reading: Mechanical oil flow meter

(6) The working environment is different from the verification environment

During the periodic verification of the flowmeter, if it is carried out in a specific device of the metrological verification unit, when it cannot be consistent with the verification conditions in use, environmental errors will also occur. Therefore, when periodic verification is required, it is required to be carried out under working conditions, that is, on-site calibration.

Flowmeter selection principle

The rational design and selection of flow meter should be a scheme with high reliability, convenient maintenance and cost saving under the premise of meeting the requirements of use.

The factors that need to be considered in the selection of flow meters mainly include: fluid characteristics, flowmeter characteristics requirements, installation conditions, environmental conditions and costs.

In addition, the selection of flow meters cannot fully pursue high performance and high precision, which not only increases the procurement cost, but also increases the cost of spare parts.

Accurate measurement and regulation of fluid flow is the basis for ensuring the safety of petrochemical production processes, improving product quality and reducing energy consumption.

Due to the complexity and diversity of the medium for flow measurement, there is no universal flowmeter, and no flowmeter can be applied to various media under any different conditions.

Each flowmeter has its advantages and limitations in measurement, and flowmeters with different principles, structures and functions play a role in their respective applicable ranges.

Therefore, the selection of flowmeters needs to follow standard specifications and selection principles, and comprehensively consider various factors that affect flow measurement.

Application of flow meter in petrochemical industry

3.1 Application in Onshore Oilfield

Constrained by various factors, the drilling of deep wells and ultra-deep wells in Youshan generally has the problem of wasting high-density weighted materials.

In order to maximize the use of weighted materials, it is necessary to combine the relevant parameters of the centrifuge, the change of density difference, the viscosity of drilling fluid and other data. With the support of the calculation flow meter sensor, accurate data information can be obtained. Working speed and processing capacity. And scientifically control it with the help of computer to achieve the purpose of recycling.

In the use of flow meters in the petroleum industry, the selection of flow meters is very important. Therefore, we must fully consider the characteristics and working principles of flow meters and choose suitable flow meters.

3.2 Application on Offshore Drilling Platforms

At present, the development of offshore oil resources is in the ascendant, and a large number of offshore drilling platforms have been put into operation. They are mainly composed of modules such as public system, process production system and auxiliary process system.

According to the functional requirements of each plate, it is determined that it needs to rely on a large number of flow meters in its role.

For example:

The main measurement uses condensate oil as the fluid medium, its parameters are viscosity 0.89cp, temperature range 42～65℃, working pressure 6690～7411KPa, conventional flow 0.521m/h.

Combine the above basic data to filter the flow meter.
First, since the petroleum medium is not conductive, electromagnetic flowmeters can be excluded;
Second, condensate is highly dependent on pipelines, which are then delivered directly to end equipment. This can exclude turbine, ultrasonic and mass flow meters;
Finally, due to the limited space of the offshore drilling platform, the differential pressure flowmeter is also difficult to apply.

In order to prevent high cost, it is also necessary to exclude flow meters and positive displacement. In order to meet the requirements of small pipe diameter and low flow rate, it is also necessary to choose a rotameter.

Working Principle of Ultrasonic Clamp on Water Flow Meter

Clamp on Ultrasonic Flow Meter adopts the measurement principle of time difference method. It uses the ultrasonic wave emitted by the sensor to propagate in the flowing fluid. The sound wave propagation speed in the downstream direction will increase, and the backward direction will decrease. In the same propagation distance, there will be different transmission times. According to the difference between the transmission time and the measured The relationship between fluid velocity measures the fluid velocity.

The flow rate of the fluid is different in different positions in the tube. The flow rate in the center of the tube is faster than the flow rate near the wall of the tube. The flow velocity distribution of the fluid in the pipeline can be represented by the flow velocity cross-sectional distribution diagram.

By setting the flowmeter and considering the cross-sectional distribution of the flow velocity, the average flow velocity can be calculated. Then the volume flow of the fluid can be obtained according to the cross-sectional area of the pipe.

Notes:
V measure fluid velocity
M ultrasonic reflection times
D pipe diameter
θ The angle between the ultrasonic signal and the fluid
T up The time when the downstream sensor transmits the signal to the upstream
T down Time from upstream sensor to downstream
ΔT = T up – T down

Recently, our company received a call from a customer asking about an ultrasonic flowmeter for measuring sewage flow.

After communication, it was learned that the customer installed flow meters for many sewage pumping stations. Some on-site installations were pipeline-type electromagnetic flowmeters. Some installed plug-in flowmeters.

The pipeline-type flowmeter was first installed on this site. Later, an insertion-type flowmeter was installed. It was broken and could not be measured normally.

However, the water cannot be stopped at present, and the pipeline-type flowmeter should be reinstalled.

Therefore, the customer came to Sino-Inst and ordered an ultrasonic flowmeter that can be installed on the outer wall of the pipeline to measure the flow. After the construction period allows, it will be replaced with a pipeline-type sewage flowmeter.

In the production of electricity, the amount of demineralized water in power plants is quite large, and how to measure the demineralized water effectively has always been a headache.

According to the traditional flowmeter selection method, orifice flowmeter or turbine flowmeter is generally used.

Some people will ask: Why not use an electromagnetic flowmeter?

Here we need to popularize a common sense about the use of electromagnetic flowmeters. Since the working principle of electromagnetic flowmeters is based on Faraday’s law of electromagnetic induction. When a conductive liquid moves in a magnetic field to cut magnetic lines of force, an induced potential is generated in the conductor. The flow of fluid in .

It is very important to note that the measuring medium must be a conductive liquid. This is the basic requirement for the electromagnetic flowmeter to work properly.

Although the electromagnetic flowmeter has high precision and stable operation, there is no problem in measuring general media, such as sewage, ionized water, acid-base salt and other solutions.

However, because the demineralized water in the power plant has low ion content and low electrical conductivity, its electrical conductivity cannot meet the measurement requirements. Therefore, the electromagnetic flowmeter cannot measure the flow of demineralized water.

Orifice flowmeters and turbine flowmeters are traditional flowmeter types. Because the measuring components need to be in direct contact with the measuring medium. There are also various defects such as blockage, poor accuracy, and troublesome installation. Its effect is also not ideal.

On site visits, we found that there are many disadvantages when using this type of flowmeter.

There are also customers who are consulting our technical department, mentioning that they have used metal rotameters, and there is no problem in measurement. Because it is desalinated by centrifugal pumps, they are often stuck by debris. Also, the pump is frequently started and stopped, and the rotor is often blocked. Broken. Ask if there are more measuring instruments and methods.

In view of this common situation. According to our experience, we recommend that you choose the outer clamp ultrasonic flowmeter, which is very effective to measure the flow rate of demineralized water.

This is the obvious difference between the external clip-on ultrasonic flowmeter and the electromagnetic flowmeter. The external clip-on ultrasonic flowmeter is not affected by the conductivity of the fluid, and can accurately measure pure water with low conductivity or low conductivity that cannot be measured by the electromagnetic flowmeter. other fluids.
The accuracy of the clip-on ultrasonic flowmeter fully meets the measurement requirements, and its accuracy is usually ±1%, and ±0.5% after correction.
Because its measuring probe is outside the pipe wall, it is closely connected with the pipe wall through a couplant, and does not directly contact the measured medium, and there is no blocking part, and its operating life can be very long. Good guarantee.
Strong anti-interference ability, wide range of power supply, to meet the needs of the scene.
The installation of the outer clamp ultrasonic flowmeter is also very convenient, as long as the outer clamp sensor is installed on the outer pipe to avoid cutting off the pipe and contaminating the demineralized water.

The clamp-on ultrasonic flowmeter is an excellent flow measurement product. Ideal for flow measurement of pipe materials such as PVC, cast steel and stainless steel.

It is not only suitable for measuring low-conductivity demineralized water or pure water that cannot be used by electromagnetic flowmeters and other products. It is also suitable for various other types of fluid media.

The accuracy of ultrasonic flowmeter in measuring liquid flow is almost not affected by the temperature, pressure, viscosity, density and other parameters of the measured fluid.

It solves the flow measurement problems of strong corrosive, non-conductive, radioactive and flammable and explosive media that are difficult to measure by other types of instruments.

For liquids with low dielectric constant, the flowmeter measuring instruments that can be used include electromagnetic flowmeters, turbine flowmeters and other products.

However, in the pharmaceutical, food and other industries, the quality of water is very high. It is often encountered that pure or ultrapure water needs to measure the flow.

What kind of flowmeter is the most suitable for pure water and ultrapure water?

We know that pure water and ultrapure water is a source of high quality water.

The filter cartridges of the ultra-clean filter units for the production of pure and ultra-pure water are made of pure polypropylene. Activated carbon is used to remove inorganic and organic trace contamination of ion exchange resins (nuclear grade) and adsorber resins. Dedicated ion exchange resins (nuclear grade) remove inorganic ions.

Dissolved organic matter is removed by adsorber resin, and the pore size of the sterile filter is 0.2 μm.

The conductivity of pure water and ultrapure water obtained by such purification equipment: 0.055 μS/cm. Bacterial content: 1 CFU/ml. It is generally used in fields with high requirements such as biopharmaceuticals.

Before choosing which flow rate, let’s first compare the application conditions of various flow meters.

Electromagnetic flowmeter. Since the conductivity of pure water is only 0.055 μS/cm. Much lower than 5 μS/cm, so electromagnetic flowmeters can only be ruled out.
Turbine flowmeter. Turbine flowmeters are contact measurements, and pure and ultrapure water are particularly demanding on materials. Therefore, the main material must be 316L during manufacture. Use hygienic clamp fittings. Production costs immediately increased considerably.
Vortex flowmeter, orifice flowmeter, etc. are all contact measurement. will undoubtedly come into direct contact with the fluid. resulting in different levels of pollution. So neither is the best choice.

So, which flowmeter to choose is the most suitable for the ultrapure water device of the pure water system?

There is no doubt that the flow measurement instrument we need has the following points:

The measuring components should not be in direct contact with the measuring medium. Make sure that the liquid to be tested cannot be contaminated in any way.
The measuring instrument must not be affected by the dielectric constant of the measured liquid.
The installation and measurement data of the measuring instrument should not be affected by the size of the measured pipe diameter.

According to the above requirements, Clamp on Water Flow Meter is undoubtedly the best representative for measuring such liquids.

Clamp on Water Flow Meter is a non-contact meter, which can measure the flow of medium with large diameter and can also be used for the measurement of medium that is difficult to touch and observe.

So far, we believe that the Clamp on Water Flow Meter is the best choice for measuring the flow of ultrapure water system purified water equipment.

After comparison, the customer found that the principle of the time difference method of using the clamp-on flowmeter was indeed suitable for him. He said he was very satisfied with the advice we gave.

We are a professional technical manufacturer of ultrasonic flowmeters, if you need it, welcome to consult!

The clamp-on ultrasonic flowmeter does not need to disconnect the pipeline and stop production during installation, which brings great convenience to the majority of users and is deeply loved by the majority of users.

But in general, it is only suitable for pipes of a single material. Such as carbon steel pipes, stainless steel pipes, PVC pipes. Measurements are not possible on lined pipes or pipes with cladding material.

However, some special pipelines can also be treated with methods to facilitate the use of clamp-on ultrasonic flowmeters.

A customer wants to measure the flow of tap water. But the pipes are galvanized pipes. Our technical engineers give the following solutions:

Connect the instrument cable first. Input the pipeline parameters after power-on, and calculate the installation distance of the probe;
Use a polisher to polish off the galvanized layer of the probe installation point on the pipeline. Until the carbon steel layer inside the pipe is exposed;
Apply the fine mixture and bind the upstream and downstream probes according to the conventional method;
Check the working status of the instrument until it works normally.

In this way, Clamp on Water Flow Meter can work well.

Our clamp-on flow meters’ accuracy is generally 1%. This accuracy has been able to meet most of the measurement needs.

The clamp-on flow meter is a flow meter with an external clamp-on flow sensor. Most flow meters are in-line pipe section mounts. The Clamp-on flow meter is a flow meter that only needs to be clamped on the outside of the pipe to measure the flow rate. This is important for many pipes that cannot be cut and bored.

Clamp-on flow sensors are based on the time difference method. The time difference caused by different propagation velocities during forward and reverse propagation is used to calculate the velocity of the measured fluid.

Clamp-on flow sensors employ two acoustic transmitters (sa and sb) and two acoustic receivers (ra and rb). Two sets of sound waves from the same sound source are transmitted between sa and ra and between sb and rb respectively.

The clamp-on ultrasonic flowmeter is installed along the pipeline at an angle of θ (generally θ=45°).

Due to the sound waves traveling downstream are accelerated by the fluid. The sound waves traveling upstream are delayed. The time difference between the clamp-on ultrasonic flowmeters is proportional to the flow rate.

You can also send a sinusoidal signal to measure the phase shift between two sets of sound waves or send a frequency signal to measure the frequency difference to measure the flow rate.

If the water meter is divided into two categories. You may be referring to velocity water meters and volumetric water meters.

In fact, water meters can be divided into 8 types according to measurement principle, measurement grade, nominal diameter, use, installation direction, temperature, pressure and form.

According to the measurement principle: speed water meter, volumetric water meter.
According to the measurement level: A-level meter, B-level meter, C-level meter, D-level meter. The larger the range, the higher the measurement level.
According to the nominal diameter: large diameter water meter, small diameter water meter.
According to the purpose: civil water meter, industrial water meter.
According to the installation direction: horizontal installation of water meters, vertical installation of water meters.
According to the temperature: cold water meter, hot water meter.
According to the pressure: ordinary water meter, high pressure water meter.
Classification by form: analog type, digital type, analog-digital combined type.
