FLR Series Thermal Gas Mass Flowmeter
Description
A thermal gas mass flow meter is designed based on the principle of thermal diffusion and uses the constant temperature difference method to accurately measure gases. It features a compact size, high digitization, easy installation, and precise measurement.
The sensor section consists of two reference-grade platinum resistance temperature sensors. During operation, one sensor continuously measures the medium temperature T1; the other is self-heated to a temperature T2 higher than the medium temperature and is used to detect the fluid flow velocity, known as the velocity sensor.
The temperature difference is ΔT = T2 – T1, where T2 > T1. When fluid flows through, gas molecules collide with the sensor and carry away heat from T2, causing its temperature to drop. To maintain a constant ΔT, the supply current to T2 must be increased. The faster the gas flows, the more heat is carried away. There is a fixed functional relationship between the gas flow rate and the increased heat, which is the basis of the constant temperature difference principle.
Advantages
It is a true mass flow meter that requires no temperature or pressure compensation for gas flow measurement, ensuring simple and accurate operation. It can provide gas mass flow or standard volumetric flow.
It features a wide turndown ratio and can measure gas velocities from as high as 100 Nm/s to as low as 0.1 Nm/s, making it suitable for gas leak detection.
It has excellent vibration resistance and a long service life. The sensor contains no moving parts or pressure-sensitive components, ensuring measurement accuracy is unaffected by vibrations.
It is easy to install and maintain. Under appropriate field conditions, installation and maintenance can be performed without shutting down production (special customization required).
It adopts a fully digital design, providing accurate measurement and easy maintenance.
With RS-485 or HART communication, it supports factory automation and system integration.
