ABSTRACT:
A flow meter for measuring extremely low flow rates of fluids by cyclically controlling the flow from a maximum to a minimum condition in the vicinity of a thermistor. The magnitude of the modulation component of the electric signal is representative of flow rate. In an alternate embodiment, the thermistor is cyclically moved in the flow stream to establish the modulation or the movement simulated by pumped flow past the thermistor.
