Medium-caliber photoelectric remote water meter, the water meter is connected and rotated by magnets, with high accuracy, stable transmission by wired remote transmission, and can realize real-time reading of water meter data, and the data presentation method is direct. It is a high-end product in today's society, and the module adopts new waterproof technology. , The waterproof effect is excellent. Compared with the traditional pulse water meter, the reading error can be reduced to zero. It is an electronic remote meter with zero error of electromechanical conversion in the automatic meter reading system. And it adopts low-power design, and usually does not need power supply. It needs to be powered only when reading the meter.
