FAQs

Q1: Can a gas 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 gas 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 gas 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: Gas mass flow meter working principle

The principle of a small flow gas mass flow meter is to use the dependence of heat and mass transfer of the flowing gas, in which the temperature change is generated upstream and downstream to obtain the mass flow of gas.

A gas mass flow meter realizes the generation of heat source and the measurement of object temperature at the same time. When the chip is in the working state, a stable temperature field distribution is formed around the sensor. Once a certain mass of gas flows through the sensor, the flow of gas will destroy the distribution of the temperature field. Sensors on the MEMS flowmeter chip measure this change and convert it into an electrical signal, which is amplified, conditioned, and linearized by a specialized circuit transmitter. The mass flow rate or total flow rate of gas can be measured due to the different disturbances caused by the formation of stable temperature field distribution around the sensor with different masses of gas.
