Product Brief

Optical direct reading meter uses optical direct reading technology to read the wheel data, compared with the traditional pulse table, it can reduce the reading error to zero, automatic meter reading system is the zero-error electromechanical conversion electronic remote meter. Optical direct reading water meter with smart meter reading system equipment to complete the smart copy of the district water, electricity, gas meter data, and network data center and settlement center to share.


Product features



Reading character wheel data directly, it reduces the reading error to zero compared to traditional pulse tables.

Low-power design requires power supply only when reading。

The use of rotor-type metering structure, high precision, easy meter reading, good looks.

The use of rotor-type metering structure, high precision, easy meter reading, good looks。

Conforms to the standard "Electronic Remote Water Meter" (CJ / T 224-2012).

Flow performance in line with GB / T 778.1 ~ 3-2007 standards, accuracy rating: Level 2.
