Photoelectric direct-reading technology, direct reading of value indicated on the window of thewater meter, accurate meter reading without accumulative error.

Provided with own patent technologies with independent intellectual knowledge to achieve thezero-error direct-reading without blind area.

No power supply in the meter, and the direct-reading device is only powered on for work at themoment of meter reading, therefore the failure rate of the system is greatly reduced and the servicelife of the product is prolonged.

The electronic parts are not in mechanical contact with the counter and other devices in the meter,free from the interference of mechanical vibration, electromagnetic action and other factors,therefore the measurement is reliable.

Unnecessary for initialization, the meter address can be flexibly set, and the work load of meterreading maintenance is minimized.

M-BUS bus standard (in accordance with EN 13757 standard), in common two-core cableconnection, with no discrimination of positive pole or negative pole, capable of synchronous datacommunication and meter power supply functions.

Wiring in a tree structure to facilitate the construction maintenance.

Provided with remote valve control function to prevent malice arrearage, and achieve thepre-charging in combination with the business management software.
