JC**0 Thermal Mass Gas Flow Meter
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.
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 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 *0℃ 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
1. Measure mass flow , no need for humidity and pressure
compensation.
2. Large rangeability, flow velocity: 0.1 Nm/s~**0Nm/s.
3. No pressure drops, applicable to any section pipe.
4. Anti-corrosion, applicable to corrosive gas.
5. Online installation and maintenance.
6. Measures mass flow directly - without additional pressure
and temperature s
7. Accurate measurement and operation at very low gas
pressures and flow rates
8. Negligible pressure drop
