TSI Low Flow Flowmeter - 20 L/min (N2O/Air/O2/N2) 1/4"
The TSI flowmeter model 41403 is from the 4130 low flow series. This version has a 0.01-20 std l/min flow measurement range, a 0.25” inlet diameter and can be used with gas calibration air, O2, N2, and N2O. It’s suitable for measuring gas flows in specific applications.
The flowmeter is highly accurate (±2% of a reading) and will response extremely quickly to flow measurements. The innovative thermal flow sensing technology and calibration gas processes mean the TSI flowmeters have a turn-down ration of 1000:1. The 41403 flow meter also has built-in temperature and pressure compensation.
- Low pressure drop function
- Analog output of flow rate
- Digital output shows flow rate, volume, pressure and temperature
- 4 millisecond flow response
