The principle and design of waterproof transmissive photoelectric direct reading water meter

Today, I will introduce a national invention authorized patent-a waterproof transmissive photoelectric direct reading water meter. The patent was applied for by Nan'an Zhonghui Electromechanical Design and Development Co., Ltd., and the authorization was announced on December 28, 2016.

Content description

The utility model relates to a water meter, in particular to a waterproof transmissive photoelectric direct reading water meter.

Background of the invention

The photoelectric direct-reading water meter adopts a rotary-wing metering structure, which has the characteristics of high metering accuracy, small starting flow, convenient meter reading, beautiful appearance, safety and health, and long life. In recent years, the remote intelligent water meter has continued to mature with its technology. It has been quickly applied and promoted, and more and more adopted by the water supply industry. The photoelectric direct reading water meter uses the photoelectric direct reading technology to read the word wheel data. Compared with the traditional pulse meter, it can reduce the reading error to Zero is an electronic remote water meter with zero error in electromechanical conversion in the automatic meter reading system. It is designed with low power consumption and usually does not need power supply. It is only needed for meter reading or valves. The photoelectric direct-reading water meter cooperates with the intelligent meter reading system equipment to complete the intelligent reading of the water, electricity and gas meter data of the community, and realizes the network data sharing with the settlement center. The existing photoelectric direct-reading water meter has low waterproof performance and cannot be effective To protect the electric board, a combination of black and white paint blocks are used on the roulette, which will fade or fall off under the influence of light, oxidation and other factors, which will directly cause direct reading errors.

Summary of the invention

The utility model provides a waterproof transmissive photoelectric direct reading water meter. By installing an auxiliary circuit board, an infrared luminous tube, an infrared receiving tube and a photoelectric sensor, it solves the problem that the existing water meters cannot be convenient and efficient for meter reading and effective waterproofing. The problem.
