An insertion type fluid volume meter and control system comprises a non-ferrous pipe, an electromagnet device, a pair of electrodes, a flow control valve, and a flow controller. The electromagnet device is for building up a pulsed square wave magnetic field across the conductive liquid flowing through the non-ferrous pipe. The pair of electrodes are disposed on outer surface of the non-ferrous pipe for detecting an electromotive force induced by Faraday's induction law. The flow control valve is disposed in the non-ferrous pipe for controlling amount of flow. The flow controller is configured to receive output signal consisting of the induced electromotive force from the pair of electrodes and control the flow control valve base on the measured flow amount. |
