The media that need to be measured at the production site are different. Now, a brief introduction to the selection of flow meters for different media is made.
1. Selection of large-flow measuring instruments for tap water: The applicable models are electromagnetic flowmeters and ultrasonic flowmeters. other such as vortex
Street flowmeters, orifice flowmeters, etc. have all faded out of this application field. These two types of flowmeters are the most important measuring instruments in the industry.
2. Selection of measuring instruments for turbid liquids such as sewage and pulp: 1. Doppler ultrasonic flowmeter and electromagnetic flowmeter can be used. However, when choosing an electromagnetic flowmeter, it should be considered that the liquid does not contain more air or air bubbles.
3. Selection of measuring instruments for liquids with more bubbles: Doppler ultrasonic flowmeter can be selected, and this type of flowmeter is used to measure fluids with bubbles, and the effect is very good.
4. Selection of flow meters with low conductivity such as pure water and demineralized water: Ultrasonic flow meters are very suitable for measuring such fluids.
5. Selection of flow meters for strong corrosive media such as acid and lye: 1. Electromagnetic flowmeter lined with acid and alkali resistance.
2. Clamp-on ultrasonic flowmeter.
6. Selection of flow meter for medium with large concentration and large solid particle content such as mortar and electro-powder slurry: electromagnetic flowmeter.
Seven, oil, diesel and other oil medium flow meter selection: ultrasonic flowmeter.
Eight, the selection of gas flowmeter: 1, ultrasonic gas flowmeter. 2. Vortex flowmeter. If the gas temperature exceeds 300℃, a pneumatic flowmeter can be selected.
