2. Benefit from output analog calibration with multi-point non-linear curve correction for unparalleled accuracy.
3. Experience a wide-range ratio of 100:1, ensuring adaptability to various flow scenarios.
4. Simultaneous flow and temperature detection with an intuitive display switching feature for seamless monitoring.
5. Capable of large-diameter, small-flow measurement, ideal for detecting leaks efficiently.
6. Utilizes proprietary "double balance structure" encapsulated sensors, setting a benchmark for precision.
7. Features advanced high humidity and high-temperature algorithms, enabling medium temperature measurements up to 300 ℃. Achieve direct mass flow detection without the need for temperature and pressure compensation.

PRINCIPLE

The thermal flowmeter shines in its design, rooted in the heat diffusion principle. As fluid flows through a heated object, the dissipated heat correlates proportionally with the flow rate. This flowmeter series incorporates two top-tier RTDs: one serves as the heat source, the other gauges fluid temperature. As fluid moves, the temperature variance between them directly corresponds to flow rate, which is expertly converted into a precise linear output via cutting-edge microelectronic control technology.
