The new affordable VA 520 flow sensor works according to the approved calorimetric measuring principle. An additional pressure and temperature compensation is not necessary. Contrary to the previously used bridge circuit the newly developed evaluation electronics records all measured values digitally. This enables very precise and fast measurements.
Due to the new evaluation electronics all VA 520’s have integrated Modbus output as a standard so all parameters can be transferred via Modbus.
Also, 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 flow sensor 520. VA 500 flow sensors are available for larger pipe diameters from DN50 to DN300. Apart from compressed air also other gases like e.g. nitrogen, oxygen and CO2 can be measured.
The majority of applications involving thermal mass flow meters are usually for compressed air monitoring from compressors or for leak detection. However, other gases such as argon, CO2, Nitrogen, Hydrogen, Helium, Propane, Methane, Oxygen end even Biogas can all be economically metered.
