Product use

Used to measure the total amount of drinking water flowing through the water pipe and through the M-BUS bus or 485 bus to the secondary instrument.


Product features



Built-in CPU, memory chip and communication module (RS485 \ M-BUS)

Just when the meter data collection power supply, read by the photoelectric meter word round wheel coding, the CPU to determine the number generated by the M_BUS bus or 485 bus output。

The meter uses a detachable screw-wing water meter, the counter is separated from the underlying structure, the reading remains clear, the counter can be replaced without stopping the water.

Maintenance of the meter need not be removed from the pipe。


Use condition

Water temperature ≤30 ℃ (cold water meter)
Water temperature ≤ 90 ℃ (hot water meter)
Water pressure ≤ 1Mpa water meter can not be immersed in water

Signal type

Optical encoding passive direct reading technology, support for DL / T 645, CJ-T188, MODBUS, industry-specific or user-specified protocol protocol; Communication transmission maximum distance: 300m; Communication transmission rate: 1200bps, 2400bps, 4800bps, 9600bps。

Maximum allowable error

1, the maximum allowable error is ± 5% in the low zone from the minimum flow rate (Q1) to the lower flow rate (Q2).
2, The maximum allowable error is ± 2% (hot water meter) ± 2。5% from the upper zone including flow rate (Q2) to overload zone (Q4)。
