The working principle of gas flowmeter is introduced

The principle of the gas flowmeter, the principle of the gas flowmeter, today's network to share with everyone is the gas flowmeter.When a triangular cylindrical vortex generator is set up in fluid mechanics, standard vortexes are generated from both sides of the vortex generator, which is called Carmen vortex.In principle, the key categories are: rate type gas flowmeter, volumetric type gas flowmeter, differential pressure type gas flowmeter, quality gas flowmeter.

The basic principle of

Thermal diffusion is the basic principle of the rapid gas mass flowmeter. Thermal diffusion technology is a technology with high performance and credibility under strict standards.Its typical sensing technology components consist of two thermal resistors (platinum RTD), one is a speed sensor, and the other is a humidity sensor that fully compensates for the gas temperature transition.When two RTD's are placed in a medium where the speed sensor is heated to a stable temperature around the operating temperature,

Another humidity sensor is used for magnetic induction of medium temperature.The mass flow of gas through the velocity sensor is measured according to the heat pair flow of the sensor component.The gas water flow rate increases, the heat carried by the medium increases.Let the controller temperature decrease as.In order to maintain a stable temperature, it is necessary to raise the current according to the work of the controller, and the size of the current of this lifting part is proportional to the water flow of the medium.

Performance features:

1, for gas flow measurement without compensation for temperature and working pressure, accurate measurement is convenient and accurate.The mass flow rate of the gas or the total flow rate of the gauge volume can be obtained.

2. Accurate measurement of water flow as high as 100Nm/s and gas as low as 0.5nm /s can be used for leakage detection.

3. Good seismic performance and long service life.The controller has no subject moving member and pressure sensitive member, so it is not affected by vibration.

4. Simple installation and maintenance.The installation and maintenance can be kept up to the standards on the spot.

5. Intelligent design scheme.The whole equipment intelligent power circuit accurate measurement, accurate measurement, convenient maintenance.
