Abstract

PURPOSE: To obtain an electronic water service meter where the an electronic circuit is protected from the humidity with low cost, by making the electronic circuit watertight by a double-structure synthetic; said circuit counts electric pulses from a magnetic sensor resin.
CONSTITUTION: Impeller 12 and permanent magnet 13 are arranged in water service meter case 11 so that they rotate in proportion to the quantity of service water, and electric pulses from magnetic sensor 21 which generates electric pulses according to rotation of permanent magnet 13 are counted by electronic counter part 22, and the count value is dispalyed on display part 23. Magnetic sensor 21, electronic counter part 22, display part 23, and power supply battery 24 which supplies the power source voltage to them are stored in the first watertight vessel 25 consisting of the synthetic resin and are fitted to water service meter part 10 through packing 31 in one body by clamp ring 32 after surrounded with the second watertight vessel consisting of the synthetic resin through filler 27, and thus, the external humidity is prevented sufficiently.
