Thermal Flow Meters A thermal flow meter can be any of an assortment of devices meant to measure the speed of a mass as it passes through a closed space, usually a pipe. As a mass moves through a closed space, a thermal flow meter detects the flow rate by measuring the heat transferred from the surface of the sensor to the flowing mass. These types of sensors depend on the rule that as the velocity changes so does the effect of a mass on measurement sensors. Sensors in a thermal flow meter many times create heat using some external source of electricity. As gas molecules pass by the sensors, they take some of that heat away along with the rest of the mass in the closed space. The electricity needed to maintain a baseline temperature will reflect the mass flow from a directly proportional relationship. Useful for many applications, a thermal flow meter might be most useful for measuring the flow rates of various gases during extraction operations.
