Description
- 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 520 work according to the approved calorimetric 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 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 520. VA 500 consumption sensors are available for larger pipe diameters from DN 50 to DN 300. Due to the new evaluation electronics all VA 520 have an integrated Modbus output as a standard. So all parameters can be transferred via Modbus 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 520 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.
