Introduction
This device is used to measure the cumulative flow and instantaneous flow of drinking water flowing through the tap water pipe. It is suitable for large-scale meter monitoring systems and secondary metering systems such as enterprises and universities.
Product features
1. Long service life.
2. Accurate reading: using infrared photoelectric direct reading technology, free from external interference.
2. Low power consumption: only connected to the power supply when collecting data, photoelectric passive direct reading code, the number is generated by the CPU and output through M-BUS or RS 485 BUS.
3. Unique structure: using dry detachable propeller mechanical structure, the counter is separated from the lower structure, and the reading remains clear permanently.
4. Easy maintenance: no need to disassemble from the pipeline, the replacement of the counter can be completed without stopping the water
Deployment conditions
1. Water temperature <50℃ (cold water meter)
2. Water temperature ≤90℃ (hot water meter)
3. Water pressure ≤1Mpa
4. The water meter cannot be immersed in water
