The versatile MAS Flowmeter digitally displays the mass flow
rate directly in engineering units or percent of full scale. The
display is tiltable over 180
°
for easy viewing and can be removed
for remote mounting on a front panel.
The Kobold MAS directly monitors the mass flow rate of the gas.
This means it measures molecular flow – the measurement quality
of direct concern in most applications, such as human respiration,
chemical processes, combustion, and heating or cooling. No
temperature or pressure corrections are required, as in the case of
most other flow monitoring devices like rotameters, turbine meters,
and orifice plates.
