VA 420

The affordable consumption in line counter for compressed air and gases

• Compressed air balancing, compressed air consumption measurement
• Leakage air / leak rate determination
• Mobile compressed air measurement in front of single machines / plants
• Flow measurement of process gases like e. g. nitrogen, CO2, oxygen, argon, nitrous oxide
• Flow measurement at nitrogen generators

Intelligent solutions for accurate consumption measurement for compressed air and gases  The new affordable consumption counters  VA 420 work according to the approved  calorimetric measuring principle.  In this process a heated sensor is cooled down by the gas circulating around it. The flowdependent  cooling-down is used as a measuring effect while the degree of  cooling-down is directly 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 (1/4” to 2 inch) with the new affordable consumption counter VA 420. VA 400 consumption sensors are available for larger pipe diameters from DN 50 to DN 300. Apart from compressed air also other gases like e. g. 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 quickly and easily for calibration or cleaning purposes without removing the complete measuring section
