Oscillating heat meter
Working principle
Digital Flow Meter uses the principal that jet flow has coanda effect in the oscillation chamber with special structure to control flow’s feedback, and in this way to make the jet flow switch between the two feedback channels. Oscillation frequency is proportional to the rate of flow, so if the oscillation chamber structural parameter is determined, a measure of total flow is derived from the measured Oscillation frequency.
