Description

[0002] Turbine flowmeter adopts turbine to measure. It converts flow velocity into the rotating speed of turbine first, and then converts the rotating speed into the electric signal proportional to flow. This flowmeter is used to detect instantaneous flow and total accumulated flow, and its output signal is frequency, which is easy to be digitized. Induction coil and permanent magnet are fixed on the shell together. When ferromagnetic turbine blade passes through the magnet, the magnetic resistance of magnetic circuit changes, thereby generating induction signal.

At the same time, the pulse frequency is converted by frequency-voltage to indicate instantaneous flow. The rotating speed of impeller is proportional to flow, and the revolution of impeller is proportional to total flow. The output of turbine flowmeter is frequency modulation signal, which not only improves the anti-interference of detection circuit, but also simplifies the flow detection system.
