The new consumption counters VA 420 work according to the approved calorimetric measuring principle. An additional pressure and temperature compensation is not necessary. Every consumption counter has an integrated measuring section (inlet and outlet section) for flow conditioning.

The consumption counters are available for all current pipe diameters like 1/2", 3/4", 1", 1 1/2" and 2". Our long-term approved VA 400 consumption sensors are available for larger pipe diameters. Apart from compressed air also other gases like e.g. nitrogen, oxygen, CO2, argon and helium can be measured.

The integrated display shows the actual consumption in m³/h and the total consumption (counter reading) in m³. At the touch of a button further units like e.g. litres/min can be selected and the counter can be set to "zero". For stationary use there are the following outputs available for the data transfer to a building management system or PLC: 4...20 mA for actual consumption, pulse output (galvanically isolated) for the total consumption.
