Remote Reading Water Meter with M-bus
1) PIC series low consumption microchips is adopted from American MicroChip company, and reduce the static power consumption.
2) Photoelectric reading technology is used and there is no power supply in meter and and direct reading device only in the moment of electric meter reading work.
3) Read meter rapidly and collect the water consumption within 0.3s.
4) Read the cyclometer data directly to ensure the Mechanical and electrical data are consistent.
5) Adopt national and international standard non-polarity two-wire bus technique, the bus transfer the signal and energy at the same time to make sure of the reliability of communication and also simple in wiring.
6) Safety Protection Class
7) High non magnetic elements and magnetic interference have no influence on measurements.
8) No battery, no memory.
9) Full-sealed waterproof, and protection class reaches IP 56.
Maximum permissible error:
1)in trie lower zone from qmin inclusive up to but excluding qt is ±5%
2)in tbe upper zone from qt inclusive up to and including qs is ±2% for (cold water meter); ±3% for hot water meten
3)Max. working pressure : <1.0Mpa. Loss of pressure:<0.1 Mp
4)Water température: 0.1 °C ~ 40°C for cold water meter 40°C ~ 90°C for hot water meter.
