Flowmeter circuit for measuring the flow rate of liquids flowing at slow speeds. To understand the principle of operation refer to Detail A. T1 and T2 are temperature sensors. With no flow through the pipe power is dissipated into the medium symmetrically and there is no difference in temperature at T1 and T2. As flow begins T1 will take on the temperature upstream, but T2 will be influenced by the power dissipated into the moving stream. The time response of the flowmeter is in the order of 10 to 15 seconds (courtesy Analog Devices, Inc.).
