Abstract

PURPOSE: To obtain an electronic water service meter where an electronic circuit part is protected from the humidity, by giving the watertight structure to the electronic circuit part by the synthetic resin; said parts counts electric pulses from a magnetic sensor, and by coating the surface of this part with the coating material.
CONSTITUTION: Permanent magnet 14 uniting with impeller 13 is constituted in water service meter case 11 so that permanent magnet 14 rotates in proportion to the water flow rate. The electronic circuit consisting of magnetic sensor 24 which generates electric pulses according to rotation of permanent magnet 14, electronic counter part 25 which counts electric pulses from magnetic sensor 24, display part which displays the value of the counter part, the power source part, and so on is stored through shield plate 12 in upper case 22 and lower case 23 made of synthetic resin water-tightly, and further, the surface is coated with the water-proof resin or metal, and therefore, the electronic circuit is prevented form the humidity.
