The heat meter consists of a calculator, a paired temperature sensor and a flow transmitter, wherein the paired temperature sensor is installed on the inlet and return water pipelines, and the flow transmitter is installed on the inlet and return water pipelines; The paired temperature sensor gives the temperature signal of the inlet and outlet, the flow sensor gives the flow signal, and the calculator collects the flow signal and the temperature signal; After calculation, it shows the heat released by the heat-carrying liquid from the inlet to the outlet.

When there is temperature (but the temperature difference is not zero) and flow, heat can be calculated, and heat has nothing to do with pressure.
