Ultrasonic calorimeter is an instrument that measures flow rate and displays the heat energy released or absorbed by water through a heat exchange system using ultrasonic methods. It measures physical quantities through two sensors – the flow rate of the heat carrier and the inlet and outlet temperatures, and then compensates and integrates density and enthalpy values to obtain the heat value. It is an electromechanical integrated product based on microprocessors and high-precision sensors. Compared with the household meters commonly used in the construction industry in the past, such as water meters, electricity meters, and gas meters, there are more complex designs and higher technological content. Ultrasonic calorimeter is a high-tech product that incorporates mechanical, electronic, and information technologies, and has been successfully applied in many fields.

Heat meter is a device that installs a pair of temperature sensors on the upstream and downstream pipes passing through the heat transfer fluid, while a flow meter is installed on the fluid inlet or return pipe (the final measurement result varies depending on the location of the flow meter installation). The flow meter emits a pulse signal proportional to the flow rate, and a pair of temperature sensors provide an analog signal representing the temperature. The integrator collects signals from the flow and temperature sensors and uses calculation formulas to calculate the heat obtained by the heat exchange system.

Working principle of ultrasonic calorimeter

The principle of ultrasonic velocity difference method (time difference method) is to measure fluid flow rate by relying on the time difference of ultrasonic signals propagating in the fluid.
When ultrasonic waves propagate in a fluid, the flow of the fluid will cause a time difference in the propagation speed of the ultrasonic signal. The magnitude of the time difference is directly proportional to the flow velocity of the fluid. Thus, the fluid flow rate can be measured.
