PRINCIPLE

Thermal flowmeters are masterpieces of engineering, meticulously designed on the heat diffusion principle. As fluids traverse a heated object, the heat dissipated correlates precisely with flow rate, thanks to the cutting-edge sensors equipped with standard-grade RTDs. These RTDs, one as a heat source and the other measuring fluid temperature, establish a linear relationship between temperature difference and flow rate. This relationship is then transformed into a precise linear output for flow measurement using advanced microelectronic control technology.
