2, Experience precision like never before with output analog calibration, enhanced through multi-point non-linear curve correction, guaranteeing accuracy in every reading.
3, Benefit from an impressive wide-range ratio of 100:1, allowing for exceptional adaptability and accuracy in varying operational conditions.
4, Seamlessly detect both flow and temperature simultaneously, with an intuitive display switch feature that enhances operational efficiency.
5, Master the art of measuring small flows in large-diameter pipes with our advanced leak detection capabilities, ensuring comprehensive monitoring and control.
6, Leverage our proprietary 'double balance structure' encapsulated sensors, providing unparalleled precision and reliability.
7, Employ our proprietary algorithms designed for high humidity and high temperature environments, enabling direct mass flow detection at temperatures up to 300 ℃ without the need for temperature and pressure compensation.

PRINCIPLE

Our thermal flowmeter ingeniously operates on heat diffusion principles. As fluid traverses a heated object, the dissipated heat directly correlates with flow rate. Equipped with dual standard-grade RTDs, our sensors capture this dynamic relationship, translating it into precise flow measurement signals through cutting-edge microelectronic control technology.
