The Role and Function of Temperature Sensors in Heat Meters
Heat meters combine flow information with the temperature difference between the flow and return sides of a heating or cooling circuit. Temperature sensors provide those readings to the meter calculator; the sensor type, installation and wiring must match the meter’s documented configuration. How temperature sensors work in a heat meter A typical heat meter uses a flow sensor, a temperature-sensor pair and a calculator. One temperature probe is installed at the designated flow point and the other at the return point. The calculator combines their readings with the flow measurement and the heat-conveying liquid data specified for the meter. OIML
