Abstract
An electronic water meter capable of implementing precision metering. The electronic water meter comprises a machine frame, multiple counter units, and multiple shielding plates. The counter units comprise numerical character wheels, magnets, magnetic angular displacement sensors, and digital circuits. The magnetic angular displacement sensors are electrically connected to the digital circuits, sense components of magnetic fields at respective positions thereof on the basis of angular position changes of magnetic field vectors of the counter units, and transmit a corresponding electric signal to the digital circuits. The digital circuits perform a calculation processing on the basis of the electrical signal outputted by the magnetic angular displacement sensors and output a digital signal corresponding to the angular positions of the numerical character wheels. The shielding plates are arranged on two sides of the counter units and are used for isolation among the multiple counter units and between the multiple counter units and the external. The electronic water meter has the advantages of a compact size, easy installation, high metering precision, and powerful anti-interference c…
