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

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).
