2, Benefit from precise output with our analog calibration, enhanced by multi-point non-linear curve correction for unmatched accuracy.
3, Achieve an astonishing wide-range measurement ratio of up to 100:1 with our advanced technology.
4, Simultaneously detect both flow and temperature, seamlessly switching the display for comprehensive monitoring.
5, Our large-diameter small-flow measurement technology excels in detecting even the smallest leaks with precision.
6, Discover the innovation of our proprietary 'double balance structure' encapsulated sensors, setting new standards in performance.
7, Harness the power of our proprietary algorithms, optimized for high humidity and temperatures up to 300 ℃. Enjoy direct mass flow detection without the need for temperature and pressure compensation.

PRINCIPLE

Experience the future of flow measurement with our thermal flowmeter, rooted in the principle of heat diffusion. As fluids traverse the heating element, heat dissipation correlates proportionately with flow rate. This sophisticated system employs dual standard-grade RTDs—one as a heat source, the other for fluid temperature assessment. The resultant temperature differential translates linearly to flow rate, culminating in a precise flow measurement signal via state-of-the-art microelectronic control technology.
