2. Benefit from output analog calibration through multi-point non-linear curve correction, enhancing your system's accuracy.
3. Enjoy a wide-range ratio of 100:1, accommodating diverse measuring needs with exceptional flexibility.
4. Simultaneously detect flow and temperature with real-time switching display capabilities, providing comprehensive data at your fingertips.
5. Our technology excels in large-diameter small-flow measurement, equipped to identify potential leakages efficiently.
6. Utilizing our proprietary 'double balance structure,' our encapsulated sensors are at the cutting edge of technology, ensuring precision and reliability.
7. Our unique algorithms for high humidity and temperature allow for medium temperature measurements up to 300℃. Direct mass flow detection is achieved without the need for temperature or pressure compensation.

PRINCIPLE

Our thermal flowmeter, rooted in the heat diffusion principle, measures fluid flow with precision. As fluid passes a heating element, the heat dissipation correlates proportionally to the flow rate. Equipped with two RTDs, one as a heat source and the other measuring fluid temperature, the resultant temperature differential is linearly related to flow. This relationship is translated into a linear flow measurement signal via advanced microelectronic control technology, ensuring accuracy and efficiency.
