0699 6447/5 6447 Compressed Air Meter by Testo
The compressed air counters testo 6441 to testo 6444 are designed for the measurement, monitoring and recording of compressed air consumption, and therefore also for the determination of leakages in compressed air systems, consumption-based allocation of costs and the implementation of peak load management. The compressed air counters testo 6441 to testo 6444 record norm volume flow according to the calorimetric principle, which means the measurement procedure is independent of the process pressure and does not cause a permanent pressure drop.
The version testo 6447 offers everything the testo 6446 provides, in addition the removal of the probe under pressure is possible (patented screw fitting). The larger nominal values refer especially to important compressed air pipelines, often the main supply line after preparation.
- Measurement of norm volume flow in the measuring range 6.7 to 27500 m3/h (DN65 to DN350 or 21/2"-10")
- Exchangeable fitting: Probe removal under pressure possible (testo 6447 only)
- Material selectable between galvanized steel and stainless steel
- Highest flexibility thanks to different signal outputs: Analog output 4 to 20 mA (4-wire), Pulse output, 2 switch outputs (parameterizable: consumption or volume flow-dependent, opener, closer, hysteresis, window)
- Built-in totalizer, even without additional analysis unit
- Operating menu with LED display
- Cleanable sensor
