Ultrasonic heat meter that measures the flow of water and the instrument by which water flow is released or absorbed by a heat exchange system. It can get the heat value through the physical quantity measured by two kinds of sensors — the heat carrier flow and the temperature of the inlet and outlet, and then compensated by the density and enthalpy value and integral calculation. It is a kind of electromechanical integration product based on microprocessor and high precision sensor. Compared with household gauges used in the construction industry, water meters, electric meters and gas meters, they have more complex designs and higher technical content. Ultrasonic heat meter is a high-tech product including mechanical, electronic and information technology. It has been successfully used in many fields.
The principle of ultrasonic difference method (TDOA) is to measure the flow of a fluid by the time difference of the ultrasonic signal flowing through the fluid.
When the ultrasonic wave propagates in the fluid, the flow of the fluid will cause the propagation time of the ultrasonic signal to propagate at a different time. The magnitude of the time difference is directly proportional to the flow velocity of the fluid. As a result, fluid flow can be measured.
