DESCRIPTION

Photoelectric direct reading water meter is an advanced smart water meter which adopts photoelectric technology to monitor the change of water flow in real time through photoelectric sensors and convert the data to electrical signals.This technology can read the digital display on the character wheel without manual meter reading,greatly improving the efficiency and accuracy of water usage management.

FEATURE

● High precision measurement:Photoelectric direct reading water meter adopts advanced photoelectric technology,which can achieve high-precision water measurement and avoid data drift or errors that may occur in traditional mechanical water meters.

● Remote monitoring:This water meter has the function of remote monitoring,which can read water usage data in real time by network connection,making it convenient for the users and managers to check the water usage situation in any time.

● Energy saving and environmental protection:Photoelectric direct reading water meter uses low power design,which doesn’t need batteries or external power supply,avoid the problem of traditional mechanical water meters requiring regular replacement batteries.
