Product Overview

A thermal gas mass flowmeter is a type of flowmeter that measures fluid mass flow by utilizing the temperature field changes generated when the fluid flows through an externally heated pipe, or by leveraging the relationship between the energy required to heat the fluid to a certain temperature rise and the fluid mass. It can conveniently measure the mass flow of gases such as natural gas, air, hydrogen, oxygen, chlorine, helium, argent gas, ammonia, marsh gas, coal gas, and flue gas (excluding acetylene) flowing in a pipeline without the need for temperature and pressure compensation.

Main Features

● A true mass flowmeter that measures gas flow without requiring temperature and pressure compensation, offering convenient, accurate measurements. It can provide gas mass flow or standard volumetric flow.

● Wide rangeability, capable of measuring gases with flow rates ranging from as high as 100 Nm/s to as low as 0.1 Nm/s, making it suitable for gas leak detection.

● Good shock resistance, long service life, with no moving parts in the sensor and pressure sensor components, ensuring measurement accuracy is unaffected by vibrations.

● Simple installation and maintenance. When on-site conditions permit, continuous production installation and maintenance can be achieved.

● Flexible installation methods. Depending on the on-site process pipeline, it can be installed horizontally, vertically, or at various angles.

● Digital design with an overall digital circuit for accurate measurement and convenient maintenance.

● Utilizes RS-485 communication or HART communication, enabling factory automation and integration.
