A thermal gas mass flow meter is a type of flow meter that measures the flow rate of gases in a pipeline. The flow rate is calculated based on the difference in temperature between the upstream and downstream sides of the sensor, and the thermal conductivity of the gas being measured.
High quality components make the measurement stable
- The thermal mass flowmeter has a wide range ratio, which makes the measurement more stable.
- A variety of signals, to achieve automation.
Adopts with stainless steel material
- The flowmeter is made of 304 stainless steel, which is resistant to corrosion and oxidation.
- All metal structure and no moving parts.
Application
The flow meter calculates the mass flow rate of the fluid based on the power required to maintain the constant temperature difference. Thermal mass flow meters are commonly used in applications where precise measurement of gas flow is required, such as in biotechnology, medical equipment, scientific research, chemical and petrochemical industry.

Q1: Can a thermal mass flow meter have perfect accuracy?
A1: In an ideal world, the flow readings from your process meter would be exactly correct, without any type of deviation. Unfortunately, this is not the case, and the errors inherent in measurement must always be identified, accounted for, and minimized as much as possible.
Q2: Does a thermal mass flow meter need to be calibrated?
A2: During the production of a flow meter, several steps are required such as coil winding, lining processing, and electrode assembly. This series of operations can cause a certain amount of error and dispersion in the device, so a calibration process is required to correct the accuracy.
Q3: Do thermal mass flow meters have temperature compensation?
A3: Yes. As long as these temperature variations are within the temperature compensation range, the output reading compensates for the temperature variations.
Tips: Thermal mass flow meter installation tips
- If the instrument is installed outdoors, it should be equipped with a sun shield to protect it from the sun and rain.
- Do not install in the place of strong vibration.
- Do not expose to environments containing large amounts of corrosive gases.
- Do not share the power supply with the equipment that pollutes the power supply, such as frequency converter and welding machine.
