LCD digital display Mixed gas Thermal mass flow meter
Thermal gas mass flow meter is designed on the basis of thermal dispersion, and adopts
method of constant differential temperature to measuring gas flow. It has advantages of
small size, easy installation, high reliability and high accuracy, etc.
The meter contains two platinum resistance temperature sensors. The thermal principle
operates by monitoring the cooling effect of a gas stream as it passes over a heated
sensor. Gas flowing through the sensing section passes over two sensors one of which is
used conventionally as a temperature sensor, whilst the other is used as a heater. The
temperature sensor monitors the actal process values whilst the heater is maintained at
a constant differential temperature above this by varying the power consumed by the
sensor. The greater the gas velocity, the greater the cooling effect and power required to
maintain the differential temperature. The measured heater power is therefore a measure
of the gas mass flow rate.
