In the world of flow meters, various units of measurement are used to quantify the flow of liquids or gases. These units help to ensure precise flow control and monitoring across industries. Let’s take a look at some of the commonly used flow meter units:

Gallons per Minute (GPM): As we discussed earlier, GPM is a popular unit for measuring liquid flow, especially in the United States, where the imperial system is widely used.

Liters per Minute (LPM): LPM is another unit for measuring liquid flow, commonly used in countries that follow the metric system. One GPM is approximately equal to 3.785 LPM.

Cubic Meters per Hour (m³/h): This unit measures the volume of gas or liquid flow per hour and is often used in large-scale applications, such as water supply networks and industrial processes.

Standard Cubic Feet per Minute (SCFM): SCFM is a unit for measuring gas flow rates. It represents the volume of gas flowing per minute, corrected to standard conditions of temperature and pressure.

Cubic Feet per Minute (CFM): Similar to SCFM, CFM is a unit for measuring gas flow rates, but without adjusting for temperature and pressure.

By understanding these commonly used flow meter units, you can better select and utilize flow meters for your specific application, ensuring accurate measurements and optimal performance.

GPM stands for gallons per minute, and it’s a measurement of the flow rate of water through a water meter. It tells you how many gallons of water are passing through the meter every minute. GPM is commonly used in the United States to measure water flow rates in residential, commercial, and industrial applications.

Reading a GPM flow meter is pretty straightforward. First, locate the flow rate indicator on the meter, usually displayed as a dial or digital readout. The number shown represents the flow rate in gallons per minute (GPM). Some meters might display the flow rate in liters per minute (L/min) or cubic meters per hour (m3/h). In these cases, you can convert the values to GPM using a conversion factor (1 L/min = 0.264172 GPM, 1 m3/h = 4.40287 GPM).

Flow Meter Selection Guide 101: Find the Perfect Fit for Your Application

The GPM for a 3/4-inch water meter can vary based on factors like water pressure and the meter’s specific design. Generally, a 3/4-inch water meter can handle a flow rate of around 10 to 30 GPM. To find the exact GPM for your 3/4-inch water meter, you can check the manufacturer’s specifications or consult with a plumber.

The formula to convert liters per minute (LPM) to US gallons per minute (GPM) is:
GPM = LPM × 0.264172

This conversion factor is derived from 1 US gallon ≈ 3.78541 liters, so 1 liter ≈ 0.264172 US gallons.

Stilling Wells for Radar Level Measurement|What Is It? Why Do You Need It?

Posted on February 3, 2023 by KimGuo11

Stilling Wells for Radar Level Measurement

Stilling Wells is our complementary tool in radar level measurement. Simply put, Stilling Wells is a metal pipe installed under the radar level meter. In many working conditions, the radar level meter is installed inside the storage tank. In order to concentrate microwave pulses and reduce scattering, one of the methods adopted is to install them in Stilling Wells. Especially for occasions where the liquid level fluctuates greatly or foam is generated.

RFQ Level Meters

When do we need to use Stilling Wells?

Usually, the radar level meter is installed in Stilling Wells because the interference signal caused by certain factors has a great influence on the real signal, resulting in measurement errors or even failure to measure. The radar level meter is installed in the Stilling Wells, which can avoid the influence of the interference signal on the real signal and ensure the accuracy of the measurement.

So, under what circumstances will the radar level meter be installed in Stilling Wells?

Situation 1: There are obstacles in the storage tank or large foam and fluctuations on the liquid level. In this case, interfering signals can significantly affect the measurement.

Situation 2: The dielectric constant of the medium is low, and the reflected echo is too small to accurately measure the liquid level. Using the radar level meter installed in Stilling Wells can increase the reflected echo energy and ensure accurate measurement.

Using Stilling Wells installation (Stilling Wells or bypass pipe), you can avoid the impact of obstacles, foam, liquid surface fluctuations in the container on the measurement.

Stilling Wells can only measure medium with good fluidity. Viscous medium cannot be measured with Stilling Wells.

Advantages of Stilling Wells for Radar Level Measurement:

The advantage of Stilling Wells measurement is that the liquid level in the pipe is stable and not disturbed by external fluctuations.
Avoid interference from obstacles inside the container.
Reduce the influence of foam and air turbulence on the measurement.
Increase signal reflection strength.
For the case where the measured object has boiling or turbulent liquid level, or the dielectric constant of the measured medium is small, measures such as Stilling Wells should be used to ensure the measurement accuracy.

The accuracy of the radar level meter differs under actual application and reference conditions. The main reason is that the tank itself has become part of the measurement system. The ability to achieve accuracy is determined by the interference of the microwaves by the tank and its internal obstructions.

After the pressure spherical tank is built, the draft tube becomes a part of the tank body. Its manufacturing process level directly affects the measurement accuracy of the radar level meter.

The electromagnetic wave emitted by the radar level meter propagates along a straight line. When interference is encountered in Stilling Wells, a reflected echo will be generated, and the echo amplitude is small. On the contrary, if the smoothness of the inner wall of the pipe is not ideal, it will show a reflection echo with a large amplitude.

Radar level meter installation standards

The installation position of the radar level meter affects the measurement accuracy. Pay full attention to several issues:

Radar level meter The distance between the tank hole and the tank wall is greater than 15% of the height between the flange sealing surface and the tank bottom plate, so it is limited to using guided waves to close the pipeline.
In order to ensure that the sound signal enters the middle of the storage tank unhindered, the total length of the flange and pipe joint of the radar level meter socket is less than 250mm.
If there is a waveguide; the waveguide should be horizontally downward, the allowable error ≤ 0.5; the verticality should be 1.
Installation and connection should take into account the strength of the tank roof so as not to cause variable displacement.
The radar wave path should avoid internal obstacles, such as brackets, heating wires, stirring rods, etc.
Consider liquid level conditions and avoid formation of air bubbles such as turbulence at the discharge end.

Radar level meter production requirements

When the storage tank is a floating roof tank or a spherical tank, a waveguide shall be used.
When the medium level fluctuates or foams, the waveguide should also be actively added.

The waveguide is not purchased together with the equipment supply, and should be manufactured on site by the supervisory unit according to the specific working conditions.

The specific conditions for manufacturing Stilling Wells are as follows:

Stilling Wells shall be constructed of stainless steel or carbon steel, and only stainless steel shall be used for spherical tanks.
Stilling Wells should be complete. If it needs to be lengthened, the jacket welding method must be used. The gap is less than 1.0mm. There should be no welds or sharp edges on the inner wall of the welding. Otherwise, its accuracy will be affected.
The bottom of the Stilling Wells is 100~150mm away from the bottom plate of the fuel tank. Then add a reflector radar inclined at 45°.
In order to ensure that the liquid levels outside the Stilling Wells are equal, the Stilling Wells must be separated at the intersection holes, and the plane of the Stilling Wells section must be smooth, otherwise false liquid levels are prone to occur. The hole spacing should be appropriate and not too large, so as not to cause fluctuations in the liquid level in the pipe;
It cannot be too small, and it is not very effective to ensure that the liquid level inside and outside the Stilling Wells is consistent.

Our experience:

Stilling Wells should be made of carbon steel or stainless steel. If it is used in spherical tanks, stainless steel must be used. This is the result of years of experience.

In addition, it is recommended that Stilling Wells be made into whole roots. If lengthening is required, the outer jacket welding method must be used. And the gap should be less than 1 mm. There must be no burrs and welds on the inner wall. Burrs and welds will interfere with the real echo signal and affect the measurement effect.

The last point, which is crucial, is directly related to whether the liquid level is true. Therefore, more attention is required. When making Stilling Wells, it is necessary to use the interval distance to cross the holes. The opening should not be too large, nor too small. If it is too large, the liquid level in the tank will fluctuate easily. If it is too small, the internal and external liquid levels of Stilling Wells cannot be guaranteed to be consistent.

Based on years of experience, some engineers have made a correspondence between the diameter and opening size of Stilling Wells. When the diameter of Stilling Wells is DN125, DN200, DN250 and DN300, the opening sizes of Stilling Wells are 0.1m, 0.4m, 0.8m and 1.2m in sequence.

The above three points are all the experience summarized by Sino-Inst. In addition, some materials have also mentioned that a certain distance should be kept between the bottom of the Stilling Wells and the bottom of the storage tank, and reflectors should be installed. If you have installation needs, you can find more relevant information or ask more relevant engineers.

In order to ensure the accuracy of radar level meter measurement, in addition to installing Stilling Wells, some can also install bypass pipes. You can choose the appropriate method according to your own working conditions.

What is a Venturi Tube? Using Efectul Venturi to Measure Flow

Posted on September 13, 2021 by KimGuo11

what is a venturi tube?

The Venturi Tube is a tubular device commonly used to measure fluid flow rates. It is based on a physical principle, the Venturi effect. This effect states that as a fluid passes through a narrow section of a pipe, its velocity increases and its pressure decreases. The design of the Venturi Tube takes advantage of this principle, with a gradually narrowing entrance and a subsequently expanding exit. As fluid enters the narrowed portion of the venturi, it accelerates, causing the pressure to decrease. This change in pressure can be measured by pressure measuring points on the pipe wall and calculated to determine the flow rate of the fluid.

Venturi Tube is a common flow measurement tool in industry. It is widely used in the measurement of various fluids because of its simple structure, good stability and high accuracy.

Venturi Effect

The Venturi effect describes the increase in velocity and decrease in pressure as a fluid passes through a narrow section of a pipe. When fluid enters a narrow section of a pipe, the flow rate increases and the corresponding pressure decreases. This effect was discovered by Italian physicist Giovanni Battista Venturi, hence its name.

This efectul venturi can be explained by Bernoulli’s equation. This equation is a fundamental law of fluid dynamics. Show that in an incompressible fluid without viscosity, the energy of the fluid along the streamline is conserved.

P + 1/2 ρ v^2 + ρ gh = constant

P represents the pressure of the fluid
ρ is the density of the fluid
v is the velocity of the fluid
g is the acceleration due to gravity
h is the height of the fluid

In practical applications, the Venturi effect allows the venturi tube to be used to measure the velocity of a fluid in a pipe, since the velocity of the fluid is proportional to the pressure difference in the pipe.

The Venturi effect is not only used in measurement tools, but is also widely used in many fields such as aircraft wing design, chimney airflow design, and underwater piping systems. It is a very important principle in fluid mechanics and has a profound impact on many branches of engineering and physics.

Venturi tube working principle

The venturi tube is composed of the following parts:

Entrance section: a short cylindrical section with a diameter of D;
Contracting section: the shape is a tapered tube, the cone angle is about 21°±2°;
Throat: a short straight pipe section with a diameter of about 1/3～1/4D and a length equal to the pipe diameter;
Diffusion section: Conical tube with a cone angle of 8°～15°. There is a pressure measuring ring at 0.25-0.75D from the end of the inlet section, with at least 4 pressure measuring holes on it, and the pressure ring leads to the pressure gauge.

In addition, in the center of the throat, there is also a multi-channel pressure measuring ring leading to the pressure gauge. The pressure difference between the inlet section and the smallest section (that is, the throat section) can be measured through the scale of the pressure gauge or the automatic recorder.

Suppose the average velocity, average pressure, and cross-sectional area at the entrance section and the throat are v1, p1, S1, and v2, p2, S2; the fluid density is ρ.

Applying Bernoulli’s theorem and the continuity equation and noting that the streamlines of average motion are of the same height, we can get:

The formula for calculating the flow rate Q can be obtained:

After knowing ρ, S1, S2 and measuring p1-p2, the flow rate Q can be obtained according to the above formula.

The main advantage of the venturi tube is its simplicity of installation. Secondly, due to its diffusion section, the fluid gradually decelerates, reducing the turbulence (see turbulence). Therefore, the pressure head loss is small, no more than 10-20% of the pressure difference between the inlet and the throat.

Venturi tube design

According to the manufacturing process and use, the venturi is divided into standard venturi, general venturi, venturi flow tube, small diameter venturi, rectangular venturi, and other structures. The detailed structure is as follows:

Structure type:

The standard (classic) Venturi tube is composed of an inlet cylindrical section A, a conical contraction section B, a cylindrical throat C, and a conical diffusion section E. The diameter of the cylinder section A is D, and its length is equal to D; the contraction section B is conical and has an included angle of 21º±1º; the throat C is a circular cylinder section with a diameter d, and its length is equal to d; the divergent section E It has a conical shape with a spread angle of 7º～ 15º.

The general-purpose venturi, like the standard venturi, is composed of an inlet cylindrical section A, a conical contraction section B, a cylindrical throat C, and a conical diffusion section E.

The general-purpose venturi adopts the method of changing the contraction angle of the standard venturi and the length of the diffusion section to make it have the advantages of venturi, greatly shortening the length of the body, and effectively reducing the pressure loss.

The Venturi flow tube is also composed of an inlet cylindrical section A, a conical contraction section B, a cylindrical throat C, and a conical diffusion section E. The Venturi flow tube adopts a special pressure method to make it widely used in the flow measurement of dirty media and mixed-phase flow.

The small diameter venturi is composed of an inlet cylindrical section A, a conical contraction section B, a cylindrical throat C, and a conical diffusion section E. The small diameter venturi adopts an integrated mechanical processing method to measure the fluid flow of small diameters. At the same time, it can use a variety of materials to meet the requirements of the on-site working conditions and can meet various connection methods such as welding, flange connection, and threaded connection.

The rectangular venturi is composed of an inlet cylindrical section A, a conical contraction section B, a cylindrical throat C, and a conical diffusion section E. Main technical parameters of rectangular venturi:

Nominal diameter: DN=1.13×(WH)0.5≤6000mm
Inlet diameter ratio W/H: 0.5≤W/H≤2.0
Throat diameter ratio w/h: 0.5≤w/h≤2.0
Equivalent β value: 0.44≤β=(w/h)0.5/(W/H)0.5≤0.74
Reynolds number range: 2×105≤ReD≤2×107
Accuracy: ±1%
Repeatability: ±1%
Working pressure: 0～25Mpa
Working temperature: -100℃～500℃
Turndown ratio: 1:10

Rectangular venturi is mainly used in power plant air supply and suction, heating furnace air supply, and suction occasions.

How does a Venturi tube measure flow?

The Venturi effect on a fluid (a fluidului) consists of a decrease in the fluid’s pressure in the region where its velocity increases, a phenomenon observed in pipes with a variable cross-section.

Using the Venturi Effect to measure flow, the simple steps are as follows:

Install the venturi: First install the venturi in the pipe where the flow is to be measured.
Connect the differential pressure sensor:
- Install a pressure sensor at the wide end and the narrow end of the venturi tube. These sensors measure the pressure difference between the two ends, which is directly related to the fluid velocity.
Reading the pressure difference:
- As fluid passes through a venturi, its velocity increases in the narrow section, causing the pressure there to drop. The differential pressure sensor reads the pressure values at the wide end and narrow end and calculates the pressure difference between the two.
Calculate flow velocity:
- Use Bernoulli’s equation and continuity equation to calculate the velocity of the fluid. v = sqrt(2(P1 – P2)/ρ). where P1 is the pressure at the wide end, P2 is the pressure at the narrow end, and ρ is the density of the fluid.
Determine the flow rate:
- Calculate the flow rate (Q), the formula is: Q = A2 × v. where A2 is the cross-sectional area of the narrow portion of the venturi tube and v is the fluid velocity calculated in the previous step.
Recording and monitoring: Continuously monitor pressure difference and flow, and record data for analysis or monitoring system status.

Venturi tube flow meter

A Venturi flow meter is a differential pressure flowmeter. The Venturi flow meter is a combination of a Venturi tube, a differential pressure transmitter, and a valve block. It is often used to measure the flow of pressure pipes.

Venturi flow meters are often used to measure the flow of fluids such as air, natural gas, coal gas, and water. It includes three parts: “constriction”, “throat” and “diffusion”. Install on the pipe where the flow rate needs to be measured.

Venturi flowmeter is a new generation of differential pressure flow measuring instruments. The basic measurement principle is a flow measurement method based on the law of conservation of energy-Berlier equation and flows continuity equation.

The throttling process of fluid flowing through the inner venturi tube is basically similar to the throttling process of fluid flowing through a classic venturi tube and an annular orifice plate.

Venturi flow meters types:

Classic Venturi:

It is applied to the flow measurement of various media and has the characteristics of small permanent pressure loss, the required long and short front and rear straight pipe sections, and long service life.

Casing type venturi:

It is mainly used in the flow measurement and control of various large-caliber and high-pressure or dangerous media in the petrochemical industry.

Venturi nozzle:

It is suitable for the measurement occasions of various media. It has the characteristics of small permanent pressure loss, a short length of the front and rear straight pipes required, and long life. The installation length of the body is shorter than that of the classic venturi.

Extended reading: What is a flow nozzle?

If it can be accurately manufactured in accordance with ASME standards, the measurement accuracy can also reach 0.5%. However, the accuracy of the domestic Venturi flowmeter is difficult to guarantee due to its manufacturing technical problems.

For the working condition of ultra-supercritical power generation, the use of the equalizing ring at the throat is a very dangerous link under high temperature and high pressure. If the equalizing ring is not used, the standard will not be met. The measurement accuracy cannot be guaranteed. This is a contradiction in the manufacture of high-pressure classic Venturi flowmeters.

The pipe is made of the same material as the inlet and outlet. Fluid scouring and abrasion of the throat are severe. Long-term measurement accuracy cannot be guaranteed. The length of the structure must be manufactured according to regulations. Otherwise, the required accuracy will not be achieved.

Due to the strict structural regulations of the classic venturi, its flow measurement range is the largest and the minimum flow ratio is very small, generally between 3 and 5.

This makes it difficult for Venturi flowmeters to meet flow measurements with large flow changes.

Since its development, venturi products have been successfully applied to the measurement of high-humidity natural gas, low-pressure dirty biogas, coke oven gas, gas, steam, hot water, high-temperature hot kerosene, etc., And the practical application range is rapidly expanding.

Besides, the venturi tube has a unique measurement advantage, for measuring conditions such as long straight pipe installation conditions, special high temperature, high pressure, strong corrosive and dirty media, and non-single phase flow measurement.

Of course, in the sewage and wastewater treatment industry, in addition to venturi flowmeters, electromagnetic flowmeters are also the first consideration for many users.
For example, if you need to measure the flow of wastewater in a 2-inch pipe. Then you can refer to Magnetic Flow Meters Guides.
