1.Zero Error: Reading digital wheel can be measured at 360 degree full circumference, the measurement resolution depends on the actual precision of the analog to digital conversion, the reading accuracy is 100%. there is no critical status and fuzzy status, no pulse cumulative error and visual error;
2.Direct Reading Without Power: No need power supply at ordinary times , only need to supply power at the moment when meter reading. Low failure rate and power consumption and long service life;
3.Strong Anti-interference: Overcoming the reading errors problem caused by the reflection and refraction of light when it path through the water bubble in the liquid seal medium of Photoelectric Wet solution. Problems caused by strong light and strong magnetic interference are overcomed toally;
4.Malfunction Protection: A malfunction protection device is designed for the bus open circuit and short circuit idle;
5.Will Not Affect the Accuracy of Original Meter: The sensor part of the direct reading meter has no mechanical contact with the counter in the water meter, which will not affect the accuracy of original water meter and completely solve the problem about accuracy of direct reading water meter;
6.Electromagnetic Compatibility: EMC testing meets national standards and overcomes the problem of direct reading water meters being affected by external electromagnetic interference.
7.Ingress Protection: IP68;
8.Innovative Structure: The electronic unit module adopts a dry-packed structure, and the electronic unit is completely isolated from the tap water in the pipeline, thereby eliminating the communication failure of the circuit from moisture;
9.Valve Control:Remote valve control(optional).
