MASS-VIEW® MASS FLOW METERS / REGULATORS / CONTROLLERS WITH LOCAL DISPLAY

The High-Tech replacement for VA meters

The innovative MASS-VIEW® flow meter series are a digital alternative to the conventional VA meters (variable area meters) or purge meters. 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. In addition to the flow meters for flow monitoring applications, flow regulators and controllers are equipped with an in-built needle valve for manual control of the gas flow. As an extra feature, the flow controller is equipped with a pressure compensation membrane, eliminating the effects of upstream pressure variations.

The MASS-VIEW series 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.
