This mass flow meter features a 22mm ISO connection. It can also be calibrated for air, oxygen, or nitrogen and has a 0 to 300 liter per minute range.
This mass flow meter features a 22mm ISO connection. It can also be calibrated for air, oxygen, or nitrogen and has a 0 to 300 liter per minute range.
Whether measuring gas flows in a laboratory or manufacturing setting, this mass flowmeter provides accurate results with multiple data output options. The display versions come complete with accessories making setup and operation fast and convenient.
One flowmeter covers the same range as three percent (or more) of full scale devices, with better accuracy at most points. Fast four-millisecond response ensures accuracy in fluctuating flows. This fast response time is ideal for closed-loop control systems and integrated volume measurements. Low pressure drop minimizes flow circuit back pressure and its impact on the system.
