Product Description

Product Description

Tianjin U-ideal Instrument Co., Ltd 
The thermal mass flowmeter is an instrument for measuring gas flow by using the principle of thermal diffusion. The sensor consists of two reference thermal resistors (RTDS). One is the speed sensor RH, and the other is the temperature sensor RMG, which measures the temperature change of the gas. When the two RTDS are placed in the measured gas, one sensor RH is heated and the other sensor RMG is used to sense the measured gas temperature. As the gas flow rate increases, the airflow carries away more heat, and the temperature of the sensor RH drops.

The Insertion thermal gas mass flowmeter can be installed and maintained online. The installation process is to first weld a base with external threads on the outer wall of the pipeline, install a 1-inch stainless steel ball valve on the base, and then use a special tool to drill a hole with a diameter of 22mm, remove the special tool after the hole is drilled, and then install the sensor on the valve and insert the sensor into the center of the pipe (the insertion position of the sensor has been determined before the factory). Insertion thermal gas mass flowmeter suitable for pipe diameter: DN32 ~ 6000mm.
