This firm has designed a new series of mass flowmeters that offers an economical, digital alternative to conventional variable-area (VA) meters (also known as purge meters). The new Mass-View flowmeter 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 totalized 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 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, with no glass components in the flow path. — Bronkhorst High-Tech B.V., Ruurlo, Netherlands
