[The latest patent of the meter] The installation structure of the water meter sensor

Content Description

The utility model relates to the field of water meter devices, in particular to a mounting structure of a water meter sensor.

Background of the invention

With the continuous promotion of smart card technology, non-contact smart cards have been widely used in bus, taxi, oil and other small payment applications for their convenience and security. In the intelligent water fee charging application where the water meter and the smart card reader are integrated, the user pre-stores a certain amount of money in the smart card. When paying, the user only needs to use the smart card, and the reader integrated with the water meter is provided according to the water meter. The use of water resources data, deducting the corresponding amount from the money deposited in the smart card, completes the process of paying the water fee.

At present, in the prior art, the sensors of the water meter are all installed inside the water meter. Such a structure is installed during the water meter manufacturing process. Since the space inside the water meter itself is relatively small, some values ​​will be blocked, and it is difficult to read the meter. In addition, the assembly is also more complicated and the assembly efficiency of workers is at the bottom.

Summary of the Invention

The purpose of the utility model is to overcome the deficiencies of the above technology and provide a water meter sensor mounting structure, which is easy to assemble.

In order to achieve the above object, the utility model adopts the following technical solutions: a mounting structure of a water meter sensor, which is characterized by comprising a water meter body and a shell buckled on the water meter body, and a sensor sealing box is fixed on the inner side of the shell. The sensor is installed in the sensor sealing box, and two sides of the sensor installation box are provided with connecting ears, and the connecting ears are connected with the shell through bolts.

The figure shows the structure of the utility model

In order to enable the sensor to be completely sealed, the upper part of the sensor capsule has a sealing cap. In the present invention, the sensor is a tunnel sensor. It has a simple structure and low energy consumption. It has high sensitivity and is not limited by size. It shows good prospects in terms of miniaturization and integration.

The beneficial effects of the utility model are: Compared with the prior art, the device seals the sensor separately, takes the position of the sensor out of the interior of the water meter, and sets a sensor that can be connected and connected by a corresponding position on the external housing. The box and the sensor can be placed in the sensor box, eliminating the space occupied by the water meter, and can be installed separately on the outside of the water meter, so the worker can assemble it very conveniently and greatly improve work efficiency.
