Mass air flow sensor air nitrogen argon thermal mass flow meter

Description of mass air flow sensor air nitrogen argon thermal mass flow meter

VA500 for flow measurement of compressed air and gases,optionally with display for flow in m3/h and total flow in m3.Contrary to the previously used bridge circuit the newly devel-oped evaluation electronics records all measured values digitally. This leads to a better accuracy also in case of large measuring spans of 1:1000.
