Stainless steel direct reading remote transmission large-diameter intelligent water meter is 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.
Stainless steel water meter is corrosion resistant, acid and alkali resistant, anti-aging, pollution-free, with high precision, large range, and no corrosion and seepage at high temperature and low temperature. It is a new product of environmental protection and energy conservation.
PRODUCT FEATURES
Built in CPU, storage chip, and communication module (RS485/M-BUS)
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
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
Stainless steel watch body is corrosion resistant, acid and alkali resistant, aging resistant and pollution-free
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 rate: 1200BPS, 2400BPS, 4800BPS, 9600BPS.
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.
