2. Benefit from our advanced output analog calibration and sophisticated multi-point non-linear curve correction, ensuring precision in every measurement.
3. Enjoy a wide-range ratio of 100:1, providing flexibility and accuracy in diverse applications.
4. Seamlessly switch between flow and temperature detection, with a user-friendly display that enhances operational efficiency.
5. Achieve precise large-diameter small-flow measurement, perfect for detecting leaks with high sensitivity.
6. Our cutting-edge 'double balance structure' encapsulated sensors, a proprietary technology, guarantee exceptional performance and reliability.
7. Utilize proprietary algorithms designed for high humidity and temperature environments, enabling direct mass flow detection up to 300 ℃ without needing temperature or pressure compensation.

This thermal flowmeter exemplifies precision engineering, designed on the foundational principle of heat diffusion. As fluid traverses a heated surface, the dissipated heat directly correlates with flow rate. Equipped with dual RTDs, one as a heat source and the other as a fluid temperature monitor, this device converts the resultant temperature differential into a precise linear flow measurement signal using advanced microelectronic technology.
