Vortex flowmeter advantages and disadvantages analysis

Project Overview

Vortex flowmeter is a flow meter commonly used in the world. Because this flowmeter has advantages that other metering instruments cannot surpass, it is widely used in thermoelectricity, petroleum, chemical industry, metallurgy, textile, papermaking, and food. It is also used in municipal engineering and environmental protection industries. In terms of steam trade settlement and measurement, Hesheng Measurement and Control LUB series vortex flowmeters are matched with high-precision pressure transmitters, temperature sensors, and intelligent flow totalizers to realize steam (gas ) Temperature, pressure, and flow are monitored online in real time to make the meter more accurate. Instrument people are no strangers to vortex flowmeters, so what are the advantages and disadvantages of vortex flowmeters?

1. Advantages

(1) Wide measurement range: The range ratio of the vortex flowmeter can reach 1:10, which can meet the measurement needs of different flow ranges.

(2) High precision: The vortex flowmeter is almost not affected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring the volume flow rate under working conditions, so it has high measurement accuracy.

(3) Small pressure loss: The design of the vortex flowmeter makes the pressure loss generated during the measurement process smaller, which helps to reduce operating costs and is more energy-saving.

(4) Simple and solid structure: The vortex flowmeter has no moving parts, has a simple and solid structure, and is very reliable in long-term operation.

(5) Easy maintenance: Because the vortex flowmeter has a simple structure and the sensor does not directly contact the medium, it is very convenient to maintain.

(6) Diverse signal outputs: Vortex flowmeters have both analog standard signal outputs and digital pulse signal outputs, which are convenient for use with digital systems such as computers.

(7) Wide scope of application: Vortex flowmeter can be used to measure the flow of various media such as gas, liquid, steam, etc., and has a wide range of applications.

(8) High reliability: The vortex flowmeter uses a piezoelectric stress sensor, which has high reliability and can work in the operating temperature range of -20°C to +250°C.

2. Disadvantages

Limited high-temperature resistance: The vortex flowmeter cannot measure fluid media with a temperature of ≥300°C, and its high-temperature resistance is low.

High requirements for straight pipe sections: Vortex flowmeters have high requirements for straight pipe sections. It is usually necessary to ensure the length of the straight pipe section of the first 40D and the last 20D to meet the measurement requirements.

Not suitable for large pipe diameters: The vortex flowmeter is not suitable for pipes with a pipe diameter larger than DN300mm, because the flow coefficient is small at this time, which may affect the measurement accuracy.

Poor seismic performance: The seismic performance of the vortex flowmeter is relatively weak, and the vibration source may cause it to produce measurement errors or even fail to work properly. Therefore, you should try to stay away from vibration sources when installing.

"Anti-vibration vortex flowmeter" is the latest generation product independently developed by Supmea Measurement and Control Technology Co., Ltd., which solves the international problems of traditional vortex flow metering range, small range and poor anti-vibration performance. problem. The LUB series vortex flow metering range is wider, the anti-vibration effect is better, and the operationMore stable, it is the preferred instrument for internal measurement assessment and trade settlement of enterprises.

Vortex flowmeters not only need to be reasonably selected and installed correctly, but also need to be carefully and regularly maintained during use, constantly accumulating experience, and improving the predictability of system failures and the ability to judge and deal with problems. So as to achieve satisfactory results and maximize its advantages.
