Compressed air meters
Suitable for fixed installation, compatible with large diameters
The testo 6456 and testo 6457 compressed air meters are used to determine, monitor, control and log compressed air consumption and thus to detect leaks in compressed air systems, to allocate costs according to consumption as well as to carry out peak load management.
The testo 6456 and testo 6457 compressed air meters record the standard volumetric flow of working compressed air according to the calorimetric principle, which means that the measurement method is independent of the process pressure and does not cause any permanent loss of pressure. The testo 6457 variant offers everything that the testo 6456 offers, plus probe removal under pressure is also possible (patented quick-change fitting). This is because larger nominal widths in particular often involve main pipelines that do not allow depressurisation for maintenance purposes.
