Thermal Mass Flow Meter - Pipeline Type

Features:

* True mass flow meter, no temperature or pressure compensation required for gas flow measurement, convenient and accurate measurement. Can obtain mass flow or standard volumetric flow of gas.

?* Wide range ratio, capable of measuring gas flow velocities as high as 100 Nm/s and as low as 0.5 Nm/s, suitable for gas leak detection.

?* Excellent shock resistance and long service life. The sensor has no moving parts or pressure sensing components, unaffected by vibration on measurement accuracy.

?* Simple installation and maintenance. Under permissible site conditions, installation and maintenance can be performed without stopping production. (Please refer to safety precautions)

?* Digital design. Fully digital circuit measurement ensures accurate measurement and convenient maintenance.

?* Equipped with RS-485 communication, enabling factory automation and integration.

Principle: The thermal gas mass flow meter is an instrument that utilizes the principle of heat conduction to measure flow. It employs the constant temperature difference method for accurate measurement of gas mass flow. It features compact size, high digitalization, easy installation, and accurate measurement.

The sensor section consists of two reference-grade platinum resistance temperature sensors. Using a bridge circuit, one sensor measures the flow temperature, while the other maintains a constant temperature difference above the fluid temperature, allowing flow measurement under high temperature and high pressure conditions.
