What to look for when measuring gases with thermal mass flow meters?

Project Overview

Thermal gas mass flow meter is a new type of flow meter that can conveniently and accurately detect the mass flow rate of various gases flowing in pipelines without temperature and pressure compensation. However, there are certain restrictions in use.

1. Thermal gas mass flowmeter cannot be used for acetylene gas and gases with high moisture content (such as steam). Because the working principle of thermal gas mass flow meters may cause their status to change.

2. The accuracy levels of thermal gas mass flow meters are 1%FS and 2%FS, which are not high in the flow meter industry. If the accuracy required on site is very high, it is not recommended to use a thermal gas mass flow meter. You can use other high-precision gas flow meters such as V-cone flow meters.

3. The measuring speed range of the thermal gas flow meter is 0.5~60m/s, which is especially suitable for gas flow measurement with large pipe diameter and low flow rate. For high flow rates, it is recommended to choose other flow meters.

When using a thermal gas mass flow meter, special attention must be paid to the above three points. If you have any ideas about the key points to note about thermal gas mass flow meters, please share them in the comment area.
