Photoelectric direct reading technology is adopted for the photoelectric direct reading water meter. Compared with the traditional pulse meters, it can reduce the reading error to zero.
Product overview
Photoelectric direct reading technology is adopted for the photoelectric direct reading water meter. Compared with the traditional pulse meters, it can reduce the reading error to zero. It is an electronic remote water meter with zero error of electromechanical conversion in automatic meter reading system.
The photoelectric direct reading water meter generally adopts M-BUS communication, and the meter does not need a built-in battery. Usually, power supply is not needed for the meter, except metering reading or valve operation, which greatly reduces meter reading rate. So, this kind of meter mainly applied in new buildings.
