Here, the higher the mass flow - the greater heat is required to maintain the temperature. One type of thermal flow meter measures how much heat is needed to keep the temperature constant. In both types, the flow of fluid passing a heated element cools it down. There are two different types of these meters. Thermal flow meters use differences in temperature to measure mass flow rate. The temperature from both sensors is compared to determine the mass flow rate - the greater the temperature difference the higher the mass flow rate. When there is no liquid flow, it is the same, but when the liquid flows, the temperature registered by sensor B is higher. Orange temperature sensors A and B measure temperature before and after the heater element H. ![]() The top picture shows the condition where the liquid is stationary and the bottom picture shows a liquid flow, as indicated by the arrows.
