Problems solved by technology
The existing magnetic sensor installation structure occupies almost 1 / 3 of the area of the dial, causing a large area of the dial to be blocked, which brings great inconvenience to the on-site observation and reading
Moreover, since the magnetic sensor outside the watch glass will inevitably block a counting axis below it, the counting axis cannot be fully displayed like the other counting axes
If it is still indicated by installing a pointer at the end of the counting shaft and making a scale on the concentric outer peripheral dial of the pointer, it is difficult to observe the hidden scale and the precise position of the pointer

The invention relates to a mechanical remote water meter counting structure. The mechanical remote water meter counting structure comprises a group of counting shafts installed on a dial plate of a base meter, a magnetic needle installed on one counting shaft and a sensor mechanism installed on the upper portion of meter glass; the sensor mechanism comprises a PCB, two magnetic-sensing sensors and a magnetic shield, and the PCB is put inside the magnetic shield; the mechanical remote water meter counting structure is characterized in that two magnets which have opposite magnetic poles are installed on the magnetic needle, the PCB is vertically installed, the two magnetic-sensing sensors are vertically fixed on the PCB, the vertical face where the PCB is located and the position where the midpoint of a connecting line of the two magnets are located are set in an eccentric mode, the vertical faces where the magnetic-sensing sensors are located are parallel to any diameter of circumferences formed by the magnets, and the distances between the magnetic-sensing sensors and the center of the connecting line of the magnets are the same. According to the mechanical remote water meter counting structure, convenience of on-site reading operation of the remote water meter dial plate can be improved to the maximum extent, and use is extremely convenient.
Description
Technical field [0001] The invention belongs to the field of water meters, in particular to a mechanical remote water meter counting structure. Background technique [0002] Most of the existing remote water meters realize electronic counting through the cooperation of a magnetic needle installed on a counting shaft inside the dial and a magnetic sensor on an external control module on the surface. In addition, the forward and reverse counting is realized through the cooperation of the two magnets on the counting axis and the two magnetic sensors on the control module. [0003] The existing magnetic sensor usually adopts a tiled structure, that is, the sensing axis of the magnetic sensor is parallel to the magnet. At the same time, a certain distance must be maintained between the two sensors to prevent mutual interference. The existing magnetic sensor installation structure occupies almost 1 / 3 of the area of the dial, which causes a large area of obstruction to the dial, whi...
