MASS-VIEW®MV-196-HE

Helium Mass Flow Meters with integrated display

MASS-VIEW® model MV-196-HE Direct Thermal Mass Flow Meters (MFMs) are suited for precise measurement of flow ranges between 0,2…10 ln/min and 1…100 ln/min helium at operating pressures up to 10 bar(g). The MFM 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.

The display features easy set up via a user-friendly menu, using a 4-way navigation push button. 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.
