Overview
Overview: The photoelectric passive direct reading water meter (large caliber) is a large caliber remote transmission water meter specially designed by our company for harsh working environments of large meters. It can be used for measuring water consumption in schools, government agencies, or industries.
Product Details
Due to the direct reading of character wheel data, the mechanical and electronic readings remain completely consistent;
The water meter works normally without a power supply and consumes no power. It can be powered instantly during meter reading;
Adopting advanced data encoding and verification techniques, with high communication reliability;
● High circulation capacity, low pressure loss, detachable structure for easy maintenance;
Compatible with multiple communication protocols including DL/T 645, CJ/T 188, Modbus, or customer specified communication protocols;
● Meet the design requirements for electromagnetic compatibility of electronic products such as EMC, ESD, EMI, etc., and achieve industry-leading levels;
The product complies with the national standard GB/T 778.1-3-2007 and the Ministry of Urban Construction standard CJ/T 224-2012;
● Optional GPRS monitoring equipment from our company can be used to achieve long-distance data transmission through the GPRS network;
The electronic unit and counting components are sealed in a sealed space composed of copper cover and glass, which is not corroded by external water and moisture, and has a waterproof rating of IP68.
● Network communication through wired RS485 or wireless NB IoT.
