The photoelectric direct reading counter code is characterized by transmissive photoelectric conversion, reading the position of the counter counter wheel position, adopting the principle of photoelectric encoder, using each character wheel as one code wheel, and five infrared receiving tubes sensing the light transmission groove on the character wheel. The level change caused by the infrared light incident is composed of a set of five digits. After decoding, it is transmitted to the system computer. The data on the meter reading interface is exactly the same as the reading value of the meter window.
