MASS-VIEW®MV-402

Gas Mass Flow Regulators with pressure compensation and integrated display

MASS-VIEW® model MV-402 Mass Flow Regulators (MFRs) are suited for precise measurement and control of flow ranges between 20…200 mln/min and 20…2000 mln/min at operating pressures up to 10 bar(g). The MFR has an integrated graphical OLED display, clearly visible at wide angles, which allows reading of actual flow (value and a bar graph), total flow and type of gas. A high quality needle valve with integrated pressure compensation offers smooth and fine adjustment of the gas flow, even at varying upstream pressures.

The display features easy set up via a user-friendly menu, using a 4-way navigation push button. The pre-installed gases eliminate the need to recalibrate for different gases and therefore reduce the cost of ownership. Additional features & functions include a variety of alarm and counter functions, an analog output signal, digital interfaces and two relay contacts.

The MASS-VIEW® series provides modern, novel and economical alternative to variable area meters (VA meters), also known as purge meters. Unlike conventional VA meters these new flow meters measure mass flow instead of volume flow.
