How to choose a flow meter for measuring media with low differential pressures?
Thread Content
When measuring certain chemical gases such as hydrogen and nitrogen, the flow rates of these gases are often low; flow meters based on the differential pressure principle are not suitable for measuring them, and ultrasonic methods also do not yield satisfactory results for measuring such gases I’d like to ask what types of flowmeters are relatively good to use. Thank you~ Thermal type? Is that okay?
I’m not sure if rotameters are feasible; we all use rotameters. Pressurized air, nitrogen, instrument air, etc.
A float flow meter can be used; it is suitable for small pipe diameters and low flow rates, with low pressure loss.
What is the approximate market price of float flow meters? What are the main brands? Why can float flow meters measure small pipe diameters and low flow rates? Hehe:,lol, I’m not very good at this, so I’d like to ask for some advice!
