Compressed air counter DN 15-50 testo 6441-6444 - 1

Compressed air counter DN 15-50 testo 6441-6444 Measurement of norm volume flow in the measuring range 0.25 to 700 m3/h (DN15 to DN50 or ½’’-2’’); consumption quantity in m3; media temperature in °C 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) m 3 /h; l/ min; m 3 Built-in totalizer, even without additional analysis unit Operating menu with LED display The compressed air counters testo 6441 to testo 6444 process regarding cost reduction measures and energy are designed for the measurement, monitoring and savings. The compressed air counters testo 6441 to testo recording of compressed air consumption, and therefore 6444 record norm volume flow according to the calorimetric also for the determination of leakages in compressed principle, which means the measurement procedure is air systems, consumption-based allocation of costs and independent of the process pressure and does not cause a the implementation of peak load management. Using permanent pressure drop. While the thermal, glass-coated the compressed air counters testo 6441 to testo 6444, ceramic sensor offers a high level of robustness and fast transparency of consumption is created for compressed response times, the integrated inflow and outflow pipes air, similarly as for the media current, water or gas, thus ensure optimum accuracy. increasing the motivation of those responsible for the
