Product Description

 

                                              Modbus Rs485/Mbus Water Meter

1. Introduction of MBUS Or Rs485 Modbus Water Meter  

The wired remote water meter uses a cable to transmit the metering data of the water meter to the electronic data collector, and then the data collector transmits it to the concentrator, which uploads it to the terminal management system through the network.
Wired remote transmission valve controlled water meter adds valve control function on the basis of the wired remote transmission water meter. We provide wired remote water meter computer management systems for customers for free. The system functions include water price setting, rate setting, quick query and recharge, resetting the balance, changing password, query history, overdraft, print receipt, etc

2.Technical parameters
.
As the word wheel data is directly read, the mechanical reading and electronic reading are completely consistent;
The water meter usually works without power supply and power consumption, and it can be powered instantaneously during meter reading;
The M-Bus bus water meter adopts the plug type waterproof plug bus, which is extremely convenient for construction, commissioning and meter replacement. It is not only reliable, but also greatly reduces the construction difficulty and workload.
 Adopt advanced data coding and verification technology, with high communication reliability
 The rotor type metering structure is adopted, with high metering accuracy, convenient meter reading and beautiful appearance;
 Compatible with a variety of communication protocols, including DL/T645, CJ/T188, Modbus or customer specified communication protocols;
 Meet the design requirements of EMC, ESD, EMI and other electronic products in terms of electromagnetic compatibility, and reach the industry-leading level;
 The product complies with the national standard GB/T 778.1~3-2007 and the standard CJ/T 224-2012 of the Ministry of Urban Construction;
 Combined with the upper computer system, establish a remote automatic meter reading management system to truly realize meter reading and monitoring automation.

6.Installation, use and maintenance methods 

6.1. A wireless remote water meter of appropriate caliber should be selected based on the pipe diameter and water consumption at the installation location.
6.2. The installation location should avoid exposure, freezing, pollution, moisture and flooding to facilitate disassembly and meter reading. During the freezing period, in addition to wrapping the water meter and water pipes, close the inlet valve of the water meter and open the outlet valve and faucet when not in use. This can prevent the water meter from being damaged due to freezing expansion. It is recommended to install it in a special water meter box.
6.3. The water meter should be installed horizontally, with the letter facing up and the arrow direction in the same direction as the water flow.
6.4. It is necessary to wash away the gravel, sediment and other debris in the newly installed pipes before installing the water meter to avoid causing water meter failure.
6.5. For accurate measurement, the faucet should be higher than the water meter.
6.6. If the water meter is installed at the boiler water inlet pipe, prevent the backflow of hot water from scalding the water meter.
6.7. The water meter should not be directly connected to the pipeline. The water meter and the pipeline should be connected through pipes, sealing washers, and connecting nuts. When disassembling the water meter, do not use hard plates to avoid twisting the case.
6.8. The water meter should be protected from excessive stress caused by pipes and fittings. If necessary, the water meter should be installed on a base or bracket.
6.9. Valves should be installed before and after the water meter to facilitate maintenance and replacement.
6.10. Do not install the water meter in a metal water meter box to avoid signal shielding and preventing remote meter reading.
