The basic principle of Pneumatech's flow meters is calorimetric measuring. This means, while measuring the thermal mass flow or standard volume flow, no additional temperature and pressure compensation is required. The standard volume is a common volumetric unit used to compare gas quantities at different pressures and temperatures. To meet various standards, the reference conditions can be set directly on the display of each flow meter. Our flow meters allow for consumption and flow measurement according to the individual requirement of our customers. All flow meters come with a factory calibration certificate.
