Fluid passes through internal flow straighteners, to stabilize turbulence, before impacting on the vaned turbine rotor which rotates at a speed proportional to the flow rate. The rotor vanes have stainless steel tips which are detected by a sensor mounted externally to the glass tube.Maximum Flow Rate = 2 - 150 L\/minElectrical Connection = Cable PlugControl Output = PulseSupply Voltage = 24 V dcDisplay Screen = NoPipe Diameter Range = 1 inMinimum Operating Temperature = 5°CMaximum Operating Temperature = +60°C
