summary:
The remote transmission valve controlled water meter adopts photoelectric direct reading technology to read the character wheel data. Compared with traditional pulse meters, it can reduce the reading error to zero. It is an electronic remote water meter with zero error in electromechanical conversion in automatic meter reading systems, and is designed with ground power consumption. It usually does not require power supply and only needs to be powered during meter reading or valve operation. The photoelectric direct reading valve controlled water meter adopts a rotor type measuring structure, which has the characteristics of high measurement accuracy, small starting flow rate, beautiful appearance, safety and hygiene.
Product Features:
- Adopting advanced data encoding and validation techniques, the communication reliability is high.
- Adopting a rotary wing metering structure, it has high measurement accuracy, convenient meter reading, and beautiful appearance.
- Compliant with the standard of Electronic Remote Water Meter (CJ/T224-2012).
- The traffic performance meets the GB/T778.1-3-2007 standard, with an accuracy level of 2.
- Compatible with multiple communication protocols: DL/T645, CJ/T188, and internal protocols.
- Meet the design requirements for electromagnetic compatibility of electronic products such as EMC, ESD, EMI, etc., and achieve industry standards.
- Combined with the upper computer system, establish a remote automatic meter reading management system to truly achieve meter reading and monitoring automation.
