DESCRIPTION :
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 principleoperates by monitoring the cooling effect of a gas stream as it passes over a heatedsensor. Gas flowing through the sensing section passes over two sensors one of which isused conventionally as a temperature sensor, whilst the other is used as a heater. Thetemperature sensor monitors the actual process values whilst the heater is maintained ata constant differential temperature above this by varying the power consumed by thesensor.
PRINCIPLE :
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 actual 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.
