Thermal Mass Flow Meter

Flange thermal gas mass flow meter is one of kind mass flow meter which Is popular in industrial applications is the way they are designed and built. The feature is no moving parts, nearly unobstructed straight through flow path, require no temperature or pressure corrections and retain accuracy over a wide range of flow rates. Straight pipe runs can be reduced by using dual-plate flow conditioning elements and installation is very simple with minimal pipe intrusions. Flange thermal gas mass flow meter size from DN10~DN2000mm

Advantages :- 

Flange thermal gas mass flow meter advantanges :

(1)Wide range ratio 1000:1;

(2)Large diameter, low flow rate, negligible pressure loss;

(3)Direct mass flow measurement without temperature and pressure compensation;

(4)Very sensitive for low flow rate measurement;

(5)Easy to design and select, easy to install and use;

(6)Suitable for all kinds of single or mixed gas flow measurement Could measure gas with flow velocity from 100Nm/s to 0.1Nm/s, which can be used for gas leak detection;

(7) No pressure loss or very small pressure loss.

Application :- 

Flange thermal gas mass flow meter application:

Thermal gas air flow meter widely use for Electric power, Petrochemical industry, Glass, Ceramics and Building materials industry, and mainly be used to meausre Dry gas, such as Air, Natural gas, LPG gas, Biogas, ect. But thermal gas mass flow couldn’d be used to measure Vapour, Humidity gas and Ethyne.

Installation :- 

nge thermal gas mass flow meter installation:

① Observe the recommended inlet and outlet requirements.

② Good engineering practice is necessary for the associated pipe work and installation.

③ Ensure correct alignment and orientation of the sensor.

④ Take measures to reduce or avoid condensation (e.g. install a condensation trap, thermal insulation, etc.).

⑤ The maximum permitted ambient temperatures and the medium temperature range must be observed.

⑥ Install the transmitter in a shaded location or use a protective sun shield.

⑦ For mechanical reasons, and in order to protect the pipe, it is advisable to support heavy sensors.

⑧ No installation in where large vibration exists

⑨ No exposure in the environment containing a lot of corrosive gas

⑩ No sharing power supply with frequency converter, electric welding machine and other machines which can make power-line interference.

Daily maintenance for flange thermal gas mass flow meter:

In the daily operation of the thermal gas mass flowmeter, check and clean the flowmeter, tighten the loose parts, find and deal with the abnormality of the flowmeter in operation in time, ensure the normal operation of the flowmeter, reduce and delay the wear of components, Extend the service life of the flowmeter. Some flowmeters will become fouling after being used for a period of time, and it must be cleaned by pickling etc. depending on the degree of fouling
