Description:

Photoelectric direct reading wired remote transmission water meter is based on ordinary water meter with photoelectric direct reading sensor, adopts character wheel scale recognition technology and photoelectric coding principle to read the position of the meter wheel at the moment of meter reading. The electronic part and the mechanical part of the base meter are not in direct contact, which does not affect the metering performance of the base meter. It supports M-Bus/RS-485 wired remote transmission, and can also integrate NB-IOT/LORA wireless communication module to realize remote meter reading.

Features:

Direct reading of character wheel data
No pulse accumulation error
No initialization required
Power supply required only when reading
No power supply inside the meter
No contact between the electronic part and the base meter
Optional wireless communication module
