1. Selection of Gas Flow Meter
Commonly used gas flow meters include vortex street, orifice plate, float, swirl vortex, gas turbine, power bar, and bend pipe. Vortex street can measure most gas media. It can measure gas volume flow rate and mass flow rate, and can be used for high temperature and high pressure search and flammable and explosive gases. Orifice plates can also measure most gas media, but due to their low measurement accuracy and the need for multiple accompanying instruments, they are expensive and have gradually been replaced by vortex streets. Float flowmeter is mainly used to measure the flow rate of small caliber instruments, which cannot be achieved by other flowmeters for small flow measurement. Weiliba is used for gas measurement. Due to the presence of tar in gas, differential pressure instruments are generally unable to measure due to blockage. It is specifically designed for gas measurement. Spiral vortex and gas turbine are mainly used for measuring media such as natural gas. Due to their cost, they are rarely chosen for other gases. Bent pipes are also suitable for most liquid measurements, with high measurement accuracy and low maintenance. Due to their high price, this type of flowmeter is only considered by some large enterprises.

1. Name and characteristics of the measured fluid (corrosiveness, viscosity, wear, etc.)
2. Working flow rate (normal flow rate, ma
3. Working pressure (maximum, minimum working pressure), if negative pressure is formed, special attention should be paid
4. Working temperature (maximum temperature)
5. The conductivity of the fluid must have a certain level of conductivity, with a conductivity of ≥ 5 μ S/cm. 6. Installation location. 7. Power supply method. 8. Process pipeline size. 9 Do you know the measurement range of the vortex flowmeter?The measurement range of vortex flowmeter is relatively wide and can be applied to flow measurement of various liquids and gases. However, the specific measurement range may vary due to factors such as measurement medium, pipe diameter, and environmental conditions. The following is a detailed introduction: Industrial water full tube vortex flowmeter is mainly used for flow measurement of small and medium pipe diameters, while plug-in vortex flowmeter can be used for flow measurement of large pipe diameter (DN ≥ 300mm) pipelines.. It is widely used in urban water pipelines and industrial water main pipelines of chemical, power, metallurgical, papermaking, chemical fiber and other enterprises, and can measure the circulating water, wastewater, waste reporting liquid, etc. in the production process. Corrosive liquids, such as sulfuric acid, hydrochloric acid, nitric acid, acetic acid, and various chemical solutions, can be accurately measured by vortex flowmeters. In recent years, vortex flowmeters with small diameters (DN ≤ 25mm) have become more suitable for measuring corrosive liquids. These flowmeters use compression molding technology, sensors are made of all plastic products, and are equipped with non-contact ultrasonic detection elements, achievi
