TSI Low Flow Flowmeter - 20L/min (N2O/Air/O2/N2) 3/8"
Model 41433 is a low flow flowmeter from TSI, with a flow measurement range of 0.01-20 std l/min. It can be used with gas calibration for Air, O2, N2, N2O and has a inlet diameter of 0.375”.
The flowmeter will accurately measure gas flows in certain applications. It has an incorporated thermal flow sensor design which helps to ensure accuracy (±2% of a reading) and an extremely fast response (4 millisecond flow response).
The TSI flowmeter 41433 also includes a low pressure drop function and a turn-down ratio of 1000:1.
- Built-in temperature and pressure compensation
- Analog output of flow rate
- Digital output shows flow rate, volume, pressure and temperature
