Overview
Introduction: Used to measure the total amount of drinking water flowing through the tap water pipeline and transmit it to the secondary instrument through M-BUS bus or 485 bus
Product Details
application
Product use
Used to measure the total amount of drinking water flowing through the tap water pipeline and transmit it to the secondary instrument through M-BUS bus or 485 bus.
Product Features
Product features
Just need to supply power when collecting water meter data, read the water meter character wheel code by the photoelectric tube, generate a number through CPU judgment, and output it through the M-BUS bus or 485 bus
Built in CPU, storage chip, and communication module (RS485 \ \ M-BUS)
This water meter adopts a detachable screw wing type water meter, with the counter separated from the lower structure to maintain clear readings. The counter can be replaced without stopping the water supply
Water meter maintenance does not require disassembly from the pipeline
Conditions of Use
Use condition
Water temperature ≤ 30 ℃ (cold water meter)
Water temperature ≤ 90 ℃ (hot water meter)
Water pressure ≤ 1Mpa, water meter cannot be immersed in water
signal type
Signal type
Optoelectronic coding passive direct reading technology, supporting DL/T 645, CJ-T188, MODBUS, industry standard or user specified communication protocol specifications; Communication transmission distance: 300m; Communication transmission rates: 1200bps, 2400bps, 4800bps, 9600bps.
Allowable error
Maximum allowable error
1. The allowable error in the low zone from including flow rate (Q1) to excluding boundary flow rate (Q2) is ± 5%.
2. The allowable error in the high zone, including flow rate (Q2) and overload flow rate (Q4), is ± 2% and ± 2.5% for the hot water meter.
