6. With our proprietary double balance structure encapsulated sensors, you receive cutting-edge performance and reliability.
7. Utilizing advanced algorithms for high humidity and high temperature, our flowmeters achieve direct mass flow detection at medium temperatures up to 300 ℃ without the need for temperature and pressure compensation.

PRINCIPLE

The thermal flowmeter, a marvel of engineering, operates on the principle of heat diffusion. As fluid traverses a heated object, the heat dissipated is proportionally linked to the fluid's flow rate. Each flowmeter in this series is equipped with dual standard-grade RTDs: one serves as the heat source, the other gauges the fluid's temperature. The resulting temperature differential is linearly tied to the flow rate, which is then translated into a precise linear output signal via sophisticated microelectronic control technology.
