GLM200 Thermal gas mass flow meter is an instrument measures flow rate according to thermal properties of gases. By detecting constant temperature difference of the medium, the flow meter is able to provide high accuracy measurement result.

Sensor part of GLM200 thermal gas mass flow meter is composed by two reference level Pt100 temperature sensors. With a bridge loop circuit, one of the temperature sensor will detect temperature of the flow while the other one will be constantly in temperature higher than the flow, thus measurement will not be affected by both high temperature and pressure conditions.
