GAS Mass Flow Meters / Mass Flow Controllers

The new MASS-VIEW® flow meter series are a digital alternative to the conventional VA meters (variable area meters) or rotameters. The MASS-VIEW® flow meter series incorporates a digital bar graph of actual gas flow, which is, thanks to the OLED (organic light emitting diode) technology, clearly visible from all angles, as well as indicating flow units, gas type and totalised figures. Also available with an optional in-built needle valve for flow control duties, it is designed to mimic the straightforward features and vertical format of the VA meter, but with the considerable added benefits of an electronic output signal, high measuring accuracy, virtual independence from gas temperature and pressure variations, freedom from parallax error and inherently safe construction, by eliminating fragile glass components in the flow path.
The MASS-VIEW® series operates on the principle of direct thermal mass flow measurement, for gas flow ranges from:
lowest range 0-0,2 ln/min up to highest range 0-200 ln/min
