VA 420 Consumption Counter

The affordable consumption counter for compressed air and gasses

Intelligent solutions for accurate consumption measurement for compreaaed air and gases

The new affordable consumption counters VA 420 work according to the approved calorimentric measuring principle, in this process a heated sensor is cooled down by the gas circulating around it. the flow-dependent cooling down is used as a measuring effect while the degree of cooling-down is directing depending on the passing air resp.gas mass. Therefore, an additional pressure and temperature compensation is not necessary.

Due to its compact design it is possible to monitor all compressed air systems from the compressor to the smallest compressed air tool (1/2 to 2 inch) with the new affordable consumption counter VA 420. VA 400 consumption sensors are available for the larger pipe diameters from ON 50 to ON 300. Apart from compressed air also other gases like eg. Nitrogen, Oxygen and CO₂ can be measured.

The installation of the compressed air counters VA 420 can be done easily and quickly. a special advantage is the removable measuring device. the measuring device can be demounted quicky and easily for calibration or cleaning purposes without removing the complete measuring sectiom.
