Klinger STG is a Thermal mass flow meter, based on the thermal dispersion principle, which can be used for measuring on clean dry gases.
STG is delivered in different versions, but common to them all is that the two temperature sensors (bodies) are located at the tip of an insertion sensor, which must be placed where the flow is desired to be monitored. This means that the sensor part itself constitutes only a slight restriction in the pipe system, and therefore it will be suitable for working at very low operating pressures.

NOTE - Thermal masseflowmeters are only for clean and dry gasses (Not Acethylene)
Thermal flow meters / switches are based on the thermal dispersion principle, a principle that describes how a heated body cools when a medium passes.
If the principle is to be used for flow measurement, it is done by controlling the heating of a body in the medium, as the heating is controlled so that there is always a constant difference temperature with an identically designed reference outside the medium, then the power to be used for heating will be proportional to the mass flow of the medium.
