testo 6441 - compressed air meter
- Parameters: standard volumetric flow rate in Nm³/h or Nl/min; consumption quantity in Nm³; media temperature in °C
- Output signals: The following 2 outputs are enabled for selection at the same time:
- Analog output, 4 to 20 mA (4-wire)
- Pulse output
- 2 switch signals, programmable (dependent on consumption or volumetric flow rate, time-based or non time-based, NC or NO contact, hysteresis, window)
- Extremely easy to operate using just 2 control buttons
- Design with inflow stretch
- Advantage: reliable accuracy, including in installed state!<
- Reason: The sensor is calibrated to the pipe section (Nm³/h not m/s) -> optimum flow profile, hence no loss of accuracy through specification of incorrect pipe diameter, incorrect positioning (depth/torsion)!
