The water meter adopts a conical silica gel waterproof pad to install a special pressure plate on a threading hole of a sensor, and is fixed in a shell by screws; the ultrasonic wave base meter and the water meter bottom shell adopt the conical silica gel waterproof pad and are fixed by screws, so that the ultrasonic wave base meter and the water meter bottom shell can effectively prevent water and also can play a role in shock prevention for a circuit board; the circuit board and the battery are provided with a specially-made waterproof cover, after the battery and the circuit board are installed, the circuit board waterproof cover and the battery waterproof cover are installed, and electronic sealant is filled in the waterproof groove.

The above technical problem of the present invention is solved by the following technical solutions: the utility model discloses a by ultrasonic wave base table, water gauge drain pan, water gauge upper cover, battery cover, circuit board waterproof cover, battery waterproof cover, circuit board, battery, the waterproof pad of toper silica gel, waterproof pad clamp plate and screw are constituteed. The base meter is an ultrasonic base meter and consists of an ultrasonic measuring pipe section, a temperature sensor, two ultrasonic transducers and a fixing piece. The ultrasonic base meter is arranged at the lower part of the bottom shell of the water meter, all sensor signal wires are transmitted into the bottom shell of the water meter from the appointed wire through holes, and the ultrasonic base meter and the bottom shell of the water meter are fixed by screws sleeved with tapered silica gel waterproof pads; signal wires of the temperature sensor and the ultrasonic transducer penetrate through the conical silica gel waterproof pad and the waterproof pad pressing plate in sequence, and the pressing plate is pressed tightly by screws; the circuit board is arranged in the bottom shell of the water meter, and the upper surface of the circuit board is covered with a circuit board waterproof cover; the battery is arranged in the battery compartment, and the battery compartment is provided with a battery waterproof cover; after the waterproof cover and the water meter are installed, a circle of glue groove is formed by the waterproof cover and the upper edge of the bottom shell of the water meter, electronic sealant is injected into the glue groove, and the water meter is completely sealed.

The utility model has the advantages that: the waterproof and moistureproof structure can effectively prevent water and damp, and the conical silica gel waterproof pad is adopted, is tightly contacted with the shell and the signal wire by virtue of strong extrusion of the pressing plate, and has a large contact surface; and the circuit board waterproof cover and the battery waterproof cover are adopted, so that the circuit board and the battery are prevented from contacting silica gel, and the follow-up maintenance and the battery replacement are facilitated.
