Abstract

PURPOSE: To obtain a small-size and universal electronic water service meter where the mass of the rotary part is small, by arranging the magnetic sensor, which detects rotation of the permanent magnet, between opposite magnetic poles of the permanent magnet which rotates together with the impeller in one body.
CONSTITUTION: Permanent magnet 12 which rotates together with the impeller in one body and has magnetic poles connected by yoke 13 is arranged in water service meter case 10. Magnetic sensor 21 which generates electric pulses according to rotation of permanent magnet 12 is provided between magnetic poles of permanent magnet 12 so that this sensor 21 interposes the rotation center of impeller 11. Further, the electronic circuit part consisting of magnetic sensor 21, electronic counter 22 which counts electric pulses from magnetic sensor 21, the display part which displays the count value, power source part 24, and so on is stored in electronic circuit incorporating watertight vessel 20 and is fastened to water service meter case 10 through packing 30 by the coupling ring, and therefore, the water service meter becomes small-size, and the rotary part becomes light-weight, and thus, the measurement precision is improved.
