pass two temperature sensors.
BCST smart flow meter Introduction
The principle is that a fluid flowing past a heated temperature sensor removes
a known quantity of heat as it passes.In a thermal flowmeter, the fluid has to
pass two temperature sensors. One sensor obtains a reference value by measuring
the actual process temperature. The second sensor is a heating element and it
receives precisely as much energy as is needed to compensate for dispersed heat
and maintain a precisely defined temperature difference.
The higher the mass flow past the heated temperature sensor, the more heat is
dissipated and the more power has to be input to the element to maintain the
temperature difference.
Heating current, therefore, is a measure of the mass flow of the gas.
Due to the sensor temperature is always 30℃ higher than the medium temperature
(environment temperature), and the meter adopts method of constant differential
temperature, therefore the meter do not need to do temperature and pressure
compensation in principle.
BCST Thermal Mass Gas Flow Meter Features
