MBUS Or Rs485 Modbus Water Meter Pulse Output
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
Technical Features:
◆ 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.
