Do you really understand the measuring range of vortex flow meters?

Project Overview

The selection of the measurement range of a vortex flowmeter is a comprehensive process that requires consideration of multiple factors to ensure the accuracy and reliability of the measurement results.

1. Liquid measurement

1. Industrial water: Vortex flowmeter can be used to measure the flow of various industrial water, which may come from chemical industry, light industry, electric power, metallurgy, etc. Building materials, petroleum and other industries, used for recycling water, waste water, waste liquid, etc. in the production process.

2. Corrosive liquids: Vortex flowmeters can also accurately measure some corrosive liquids, such as sulfuric acid, hydrochloric acid, nitric acid, acetic acid and other acids, as well as various chemical solutions. In recent years, vortex flowmeters with small diameters (DN ≤ 25mm) are more suitable for the measurement of corrosive liquids. These flowmeters adopt a molding process, the sensors are all-plastic products, and are equipped with non-contact ultrasonic detection components to achieve Non-contact measurement of liquids.

3. Non-conductive liquid: In terms of flow measurement of conductive liquids, electromagnetic flowmeters dominate, but in flow measurement of non-conductive liquids, vortex flowmeters have significant advantages. For example, pure water and ultra-pure water in the semiconductor industry.

4. Oil products: Vortex flow meters can be used to measure the flow of some low-viscosity oil products, such as gasoline, kerosene, diesel, as well as heavy oil and residual oil whose viscosity is reduced after heating.

2. Gas measurement

Vortex flow meters are also suitable for gas flow measurement, including air, oxygen, nitrogen, coal gas, natural gas, chemical gases, etc. However, it should be noted that for gas measurement, the technical parameters of the vortex flowmeter (such as accuracy level) may be different from liquid measurement.

3. Steam measurement

The remote compensation type vortex flowmeter is mainly used to measure saturated steam in the pressure or temperature independent compensation mode. This kind of flow meter separates the sensor part and the display part. The display part can be placed anywhere within a certain range for easy viewing and recording.

4. Pipe diameter adaptability

The vortex flowmeter is suitable for pipe flow measurement of different pipe diameters. The full-tube vortex flowmeter is mainly used for flow measurement of small and medium-sized pipes, while the insertion vortex flowmeter can be used for flow measurement of large-diameter (DN ≥ 300mm) pipes. This makes vortex flowmeters widely used in urban water pipelines and industrial water main lines in chemical, electric power, metallurgy, papermaking, chemical fiber and other enterprises.

5. Technical parameters

The technical parameters of the vortex flowmeter include accuracy level (liquid level 1.0, gas level 1.5), nominal pressure, measured medium temperature, pressure loss, Repeatability error, flow range, power supply, output signal and usage environment conditions, etc. These parameters are critical to the selection and use of vortex flowmeters.

Qingdao Hesheng Measurement and Control Vortex Flowmeter has a rich product series, including: flange mounting type, flange connection type, temperature and pressure compensation type, local display type, split high temperature type, H series, etc. , measuring range of vortex flowmeterSelection is a process that requires comprehensive consideration of multiple factors. Choosing the appropriate installation method and model and paying attention to the maintenance and calibration of the flow meter can ensure that the vortex flow meter can achieve good measurement results in practical applications.
