Other Flow Meters
The MTRL thermal gas mass flowmeter is an instrument that uses the principle of heat conduction to measure fluid flow. The instrument uses the constant temperature difference method to accurately measure the gas mass flow rate. It has the advantages of small size, high digitization, easy installation and accurate measurement. The thermal gas mass flowmeter consists of two parts: flow transmitter and flow sensor. According to the sensor type is divided into: insert type and tube segment type hot gas mass flowmeter. According to the structure type, it can be divided into integrated type and subtype.
