Overview
Built-in photoelectricity direct reading module is provided on basis of common wet type base meter to form photoelectricity direct reading remote transmission water meter which adopts character wheel scale identification technology and phototube coding principle, reads the position state of digital wheel at the moment of reading, and transfers the reading to the water meter data collector. It owns the advantages such as advanced structure, accurate metering, convenient maintenance and strong interference resistance capacity etc. The product satisfies the National Standard GB/T778.1~3-2007 Measurement on Water Flow in Enclosed Pipelines, Cold Drinking Water and Hot Water Meter and Standard of Construction Ministry CJ/T188-2004 Indoor-applied Metering Meter Data Transmission Technical Conditions and CJ/T224-2012 Electronic Remote Water Meter.

Features:

• It only requires the power supply at the moment of reading, but no electrical consumption in remaining period, which can be used for a long time.
• No fault source. It generates no fault because of vibration resulting from pipes and other factors, and generates no fault because of magnetic interference.
• It adopts photoelectricity direct reading technique, with accurate reading, hardly generating the electronic and mechanical deviations.
• The product has low power consumption. Multiple meters are connected on same bus, which is convenient for networking.
• It has high protection grade. Character wheel inside meter is treated with liquid seal, with the clear reading, which is not easy to be polluted by water quality.
• It uses M-BUS communication method, which is convenient for networking and reading, without the operation for home-entry reading.

Each water meter has its own electronic identity code which is convenient for management and maintenance.
