High Pressure Mass Flow Meter

The principle of Coriolis mass flow meter mass measurement is Newton’s second law F=Ma.
When the fluid flows in the vibrating tube, it will produce Coriolis force proportional to the mass flow. When there is no fluid flowing, the vibrating tube does not produce distortion. The signals detected by the electromagnetic signal detectors on both sides of the vibrating tube are in the same phase.

When fluid passes through, the vibrating tube is twisted under the action of a torque. There will be a phase difference between the two detectors. The transmitter measures the lag time between the left and right detection signals. This time difference is multiplied by the flow calibration coefficient to determine the mass flow.

The density measurement principle of Coriolis mass flowmeter is that the vibration frequency is inversely proportional to the square root of the fluid density, and the fluid density is determined by measuring the vibration frequency. Therefore, the mass flow meter can realize the measurement of fluid mass flow and the measurement of fluid density.

Coriolis mass flow meters are shipped as standard with 1.6MPa and 4MPa. It supports customers’ special customized pressure levels. The highest pressure can reach 100MPa.

Liquid Flow Meter

When measuring the liquid flow of large-diameter pipes, the following factors should be considered when choosing a flow meter:

• The pressure loss should be as small as possible;
• Due to the low flow rate (to reduce operating costs), the inner wall of the pipeline is easy to deposit dirt and sludge;
• The measurement range of the flowmeter used should be particularly large to adapt to the disparity of browsing in different time periods;
• The protection level of the flowmeter should also meet the requirements of the environment.

There are several types of flow meters commonly used to measure liquid flow in large-diameter pipes.

Gas Flow Meter

The flow meters commonly used to measure gas flow in large-diameter pipelines are as follows:

(1) Orifice flowmeter

The standard orifice flowmeter is a widely used flowmeter. The advantage of the standard orifice flowmeter is that it is simple to manufacture and can be used directly without real flow calibration.

(2) Thermal gas mass flow meter

The sensor part of the thermal gas mass flowmeter consists of two reference-level platinum resistance temperature sensors. A bridging loop is used.

One sensor measures the fluid temperature. The other sensor is a heating element to maintain a constant temperature difference higher than the fluid temperature. That is, the gas flow The heat is taken away when passing the heating element.

The heat taken away is proportional to the flow rate of the gas and the density of the gas. In order to maintain a fixed temperature difference between the two temperature sensors, the circuit needs to provide more power to the heating element. The output power in the circuit is related to the quality of the fluid, and thus the flow rate is measured.

(3) Insertion vortex flowmeter

The insertion vortex flowmeter is mainly used for the flow measurement of industrial pipeline medium fluid. Such as gas, liquid, vapor, and other media. The plug-in vortex flowmeter adopts a piezoelectric stress sensor with high reliability. It can work in the working temperature range of -20℃～+350℃.

Magnetic flow meters for wastewater

According to the situation of the wastewater treatment site, there are two general wastewater discharge methods. One is to discharge through pipes, and the other is to discharge through ditches. The two types of flow meters selected are therefore different.

1.Waste water is used for pipeline discharge, and most of them choose electromagnetic flowmeter to measure. Because there are no obstructions in the sensor, there is no fear of debris in the medium.

But need to pay attention to the medium must be full. If the pipe is not full, a pipe must be used to lead a section of the sinking pipe to ensure that the flowmeter is in a full pipe.

Note that the electromagnetic flowmeter cannot be installed at the drain of the pipeline, and the length of the straight pipe must meet the requirements of the flowmeter.

2.Wastewater is used for ditch discharge, mostly using ultrasonic open channel flow meters.

A measuring groove is installed at the discharge port, and an ultrasonic probe is installed directly above the groove. In this way, the flow of wastewater flowing through can be measured. This instrument generally uses 24V power supply, output: 4-20MA.

When selecting the electromagnetic flowmeter for waste water, it is necessary to know the temperature of the medium, the pressure of the medium, the flow range of the medium, the composition of the medium, the power supply requirements, and the on-site installation requirements. The key point of the selection is to choose which product to measure well. The second is to consider the convenience of installation, operation and maintenance. Finally, the product price can be considered.

Flow Meter for Measuring Corrosive Liquids

Stainless Steel Flow Meter is a kind of electromagnetic flow meter. It can be used to measure the flow of strong corrosive liquids such as acid, alkali and salt solution.

In the process of industrial consumption, many media are slightly or extremely corrosive. However, due to consumer demand, we also need to measure these media.

How to choose a suitable flow meter? How to choose a flow meter for measuring corrosive media?

1.Corrosion

Corrosion is a phenomenon in which metals are destroyed due to chemical effects in their environment. All metals and alloys can be corrosion resistant in certain specific environments.

But in other environments it is very sensitive to corrosion. Generally speaking, there are no industrial metal materials that are resistant to corrosion in all environments.

Corrosion can be divided into uniform corrosion (uniform corrosion) or general corrosion (general corrosion) and partial corrosion (localized corrosion).

The corrosion rate of general corrosion can be expressed in units such as mm/a. Usually, the data whose corrosion rate is below 0.1mm/a is converted to corrosion-resistant data. The corrosion rate is one order of magnitude larger than this, that is, the corrosion rate is 1mm/a.

Information about common equipment can sometimes be determined as applicable. Regarding the measuring element of the flow meter, it is not allowed. Based on the corrosion rate, the service life of the metal can be predicted.

2.Damage to the flowmeter caused by corrosive media

The corrosiveness of the medium is a serious threat to the flowmeter. Only certain types of flow meters such as clamp-on ultrasonic flow meters are less affected by corrosion.

a. Corrosive media will corrode the parts that are in direct contact with the flowmeter. Make it damaged and lose its function. For example, corrosion damage to the diaphragm of the differential pressure transmitter, and complete failure due to leakage of silicone oil. The electrode is corroded, causing the medium to be out of the world, causing the excitation coil to burn out.

b. The parts of the flowmeter are corroded by corrosive media for a long time and the geometric dimensions are changed. Cause the accuracy of the instrument to decrease. For example, after the rotor in the rotameter is corroded by the fluid, the outer dimension is reduced.

As a result, the flow indication is low. Another example is that the vortex generator in the vortex flowmeter is corroded by the fluid and the width is reduced. The appearance of the front flow surface becomes rough, causing changes in the flow coefficient.

There are also clamp-on ultrasonic flowmeters that are less affected by corrosive media. It is also often caused by the corrosion of he metal pipe by the medium. It weakens the transmitting and receiving signals, and loses flexibility in severe cases.

c. Shorten the life of the instrument. For example, the conical tube and other parts in the metal tube float flowmeter. After several years, the welds were worn out.

d. Leakage of corrosive media. If it is not discovered and disposed of in time, it will easily lead to safety and personal accidents.

According to long-term inspection, electromagnetic flowmeter and ultrasonic flowmeter are selected for common corrosive liquid measurement. If it is corrosive gas, you can choose acid-resistant stainless steel vortex flowmeter or other gas flowmeter.

The electromagnetic flowmeter for measuring liquid media can measure various corrosive media containing tiny particles. Of course, the premise is that the measured medium is conductive. It is only necessary to use different lining materials and electrode materials according to the corrosiveness of the medium to deal with the corrosion problem of the medium belt.

Ultrasound is even simpler. If you choose a clamp-on ultrasonic flowmeter, you don’t have to think about the corrosiveness of the medium at all. It’s just not as high as an electromagnetic flowmeter in measurement accuracy.

3.Measures for fluid corrosion in flow measurement

(1) Change the instrument regularly

Corrosive media can corrode metals in various conditions. Some corrosion rate is very fast, that is, full corrosion. Some corrosion is subtle, very slow, that is, partial corrosion. When making instrument selection, it should be analyzed in detail according to the detailed situation. Then make a decision.

For example, compressed air and water are generally considered to be non-corrosive, but they are not. Because the concentration of nitrogen and oxygen compounds in the atmosphere in urban areas is generally higher. When it is absorbed by the condensate in the compressed air. The condensate is acidic. Thereby it has slight corrosion to carbon steel materials.

This situation is more serious in plant areas such as sulfuric acid plants, nitric acid plants, and chlor-alkali plants. Of course, in addition to dilute nitric acid, sulfuric acid and hydrochloric acid may be contained in the compressed air at this time. The water situation is similar. Especially river water. Because it contains a variety of ions, it also corrodes carbon steel. Instruments used under this condition will show signs of corrosion after several years.

For example, it was found that the surface of the carbon steel ring chamber in contact with the fluid in the flow throttling installation was corroded. Become bumpy. In severe cases, the geometric size and appearance will change greatly. The inner walls of the front and rear straight pipe sections also become uneven. This situation does not meet the requirements of the verification procedures. It is difficult to guarantee the accuracy of the original instrument.

At this time, a problem arises. Is it possible to design and select the annular chamber and the front and rear straight pipe sections in the throttling installation to be changed to stainless steel?

Of course, if it is changed to stainless steel. The corrosion problem of the annular chamber and straight pipe section will certainly be solved, but at the same time the investment has increased. And the increase in investment is related to the pipe diameter. If the nominal diameter is larger. The increase in technology capital is not a small number.

Therefore, the decision-making should be based on the measurement accuracy request of the detailed measurement point, the severity level of corrosion, the life expectancy, and the budget acceptance ability. Weigh the pros and cons, and control responsively.

If the measurement accuracy is not high. Such as for process monitoring and control. Slightly corroded, carbon steel materials can also be used for many years. After the change to stainless steel, the investment increased more. Then, it’s better to wait for the ring chamber to be corroded and unable to continue to be used. Then update the entire or damaged part of the throttling installation.

(2) Avoid the heavy

Avoiding the heavy and the light is based on a deep understanding of the process flow and the characteristics of the relevant media. Choose a measurement plan reasonably. It can also achieve the purpose of metering or stopping control of the consumption process. Avoid highly corrosive parts. And choose the less corrosive part. Even change the variety of adjusted parameters.

For example, the flow rate constant value adjustment system can be replaced by liquid level average adjustment or other suitable variable adjustment. So as to avoid the problem of corrosion resistance of flow measuring instruments.

For example, the flow of sewage into sewage treatment plants must be measured. In order to control the total discharge of pollutants. The sewage is generally acidic or alkaline. And correspondingly, an appropriate amount of alkali or acid should be added to neutralize it. Then, consider the corrosion of sewage to the flow meter. Of course, it is better to select the flow detection point after neutralization.

The flow measurement of raw gas also has a similar situation. Raw gas often contains a certain amount of sulfur dioxide. This gas is not very corrosive in boring hours. But after the wild gas is separated from the furnace. With the increase of the transfer interval. The gas temperature gradually decreases. The temperature rises accordingly. And it quickly shows condensate and is highly corrosive. When considering the location of the gas flow measuring instrument device. Of course, it should be selected before the gas presents condensate.

(3) Choose an instrument with corrosion resistance

①The instrument selection of common acid medium.

In the vortex flow sensor and turbine flow sensor, the part in contact with the fluid is acid-resistant steel. Ordinary acidic liquids and gases can be used.
The oval gear flowmeter made of acid-resistant steel can meet the needs of accurate measurement of ordinary acid liquids.

②The instrument selection of conductive liquid.

There are many kinds of lining materials for measuring tube of electromagnetic flowmeter.

Among them, the good corrosion resistance is polytetrafluoroethylene. There are also several kinds of electrode materials, which can meet the needs of most corrosive media.

When selecting electrode materials, the requirements should be met. Don’t be superstitious about precious metals. Because precious metals are not omnipotent.

Other catalysts like platinum electrodes have also attracted people’s attention. In chemical consumption, platinum is a very good catalyst. Certain media react chemically after contact with platinum under certain conditions. Proven hydrogen peroxide. The platinum electrode electromagnetic flowmeter is measuring hydrogen peroxide. Aerosol will be generated on the surface of the electrode. When the flow is zero. The output will also fluctuate.

Select appropriate electrode materials and lining materials to measure the flow of corrosive media. If the fluid temperature is also within the allowable range. That is the ideal choice, its measurement accuracy can reach 0.3~1%R.

Magnetic flowmeter can meet the needs of various measurement ranges. But if the fluid does not conduct electricity, the electromagnetic flowmeter is powerless.

③The instrument selection of non-conductive liquid.

When the clamp-on ultrasonic flowmeter works, the fluid does not directly contact the meter. Therefore, it is suitable for various corrosive fluids.

There are two types of clamp-on ultrasonic flowmeters according to their principles. Jet lag and Doppler.

The time difference method is suitable for clean single-phase fluids. The accuracy is related to pipe diameter and flow rate.
E.g:
a. When pipe diameter>150mm, v>0.3m/s, the uncertainty is ±2%R (it can reach ±1% R after calibration). v ≤0.3m/s, the uncertainty is ±O.Olm/s.
b. When the pipe diameter is ≤150mm, v>0.3m/s, the uncertainty is ±5%. v≤0.3m/s, the uncertainty is ±0.05m/s.

The Doppler flowmeter is suitable for liquids with high solid content or bubbles. The uncertainty can only reach ±1%~±10%. Obviously much lower than the electromagnetic flowmeter. Therefore, use it only when there is no other better method. The price has nothing to do with the pipe diameter. When DN≤200, ultrasonic meters are more expensive than electromagnetic flowmeters. When DN≥250, the ultrasonic flowmeter is cheaper than the electromagnetic flowmeter.

④ Selection of corrosive gas instruments

a. Ultrasonic flow meter.

In recent years, the domestic and foreign natural gas industry has achieved rapid development. This has greatly promoted the development of natural gas metering instruments. Among them, the multi-channel ultrasonic flowmeter specially developed for natural gas measurement is a dazzling pearl. If this technology is transplanted for corrosive gas flow measurement, it should be feasible. Because only the inner wall of the measuring tube needs to be treated for corrosion prevention.

b. Throttle differential pressure flowmeter.

There are no reports of commercial throttling differential pressure flow meters suitable for corrosive media. However, such meters developed by users themselves were reported decades ago.
