testo 6440 Compressed Air flowmeter

Common models (4 kinds):
DN 15: 0,25 ~ 75 Nm3/h

DN 25: 0,75 ~ 225 Nm3/h

DN 40: 1,3 ~ 410 Nm3/h

DN 50: 2,3 ~ 700 Nm3/h

Disy parameters: standard volume flow Nm³/h or Nl/min; Cumulative flow rate Nm³; Medium temperature °C
Signal output: Two output modes can be selected at the same time
Analog output: 4 ~ 20 mA (4 wire system)
Pulse output :
Dual switch output, variable can be set (according to consumption or flow; Time limit or non time limit, hysteresis and other conditions to set)
The operation is simple and can be operated by 2 control keys
Instrument design reserved tube, easy to install
Advantage: reliable measurement, to ensure the accuracy of measurement
Reason: Sensor calibration according to different pipe diameters (direct calibration of flow rather than velocity) -> The best model to reduce the error caused by irregular pipe diameter specifications and improperly determined position (depth and Angle)!
