Selection and application of flow meters with different media
The media that need to be measured in the production site are different. This paper briefly introduces the selection of flow meters with different media& nbsp;
1、 Type selection of large flow meter for tap water: electromagnetic flowmeter and ultrasonic flowmeter are applicable. Others such as vortex flowmeter and orifice flowmeter have faded out of this application field. These two types of flowmeter are the most important measuring instruments in this industry. In particular, it should be mentioned that Shanghai Heji's plug-in flowmeter and electromagnetic flowmeter have better performance price ratio for the flowmeter of super large pipeline (above DN500)& nbsp;
2、 Sewage, pulp and other turbid liquid measuring instrument selection: 1, can use Doppler ultrasonic flowmeter and electromagnetic flowmeter. But in the selection of electromagnetic flow meter, we should consider that the liquid does not contain more air or bubbles& nbsp;
3、 Type selection of measuring instrument for liquid with more bubbles: Doppler ultrasonic flowmeter can be selected, and the effect is very good when using this type of flowmeter to measure liquid with bubbles& nbsp;
4、 Type selection of flow instruments with low conductivity such as purified water and desalted water: ultrasonic flowmeter is very suitable for measuring this kind of fluid. If ds-wjf, ds-wjp external clip ultrasonic flowmeter is used, it is not only easy to install, but also does not pollute the measured liquid& nbsp;
5、 Selection of flow meter for acid, alkali and other corrosive media: 1. Electromagnetic flowmeter with acid and alkali resistant lining. 2. External clip ultrasonic flowmeter& nbsp;
6、 Selection of flow meter for medium with large concentration and solid particle content such as mortar and electric powder slurry: electromagnetic flowmeter& nbsp;
7、 Type selection of flow meter for petroleum, diesel and other oil media: ultrasonic flowmeter& nbsp;
8、 Selection of gas flowmeter: 1. Ultrasonic gas flowmeter. 2. Vortex flowmeter. If the gas temperature exceeds 300 ℃, pneumatic flowmeter can be selected.
