Factory Free sample Surge Arrestors - LXSGY Photoelectric remote valve-controlled water meter – Haimei

An intelligent water meter with valve control is used as the base meter, and an optoelectronic device and a single chip microcomputer, a communication module, and a control circuit are embedded in the water meter counter box. There is no battery in the meter. Optoelectronic devices are inserted on both sides of the character wheel, and the character wheel is provided with an identification hole for an electronic code. There are 5 pairs of optoelectronic devices on each character wheel to read the electronic code on the character wheel, and the single-chip microcomputer analyzes the read electronic code and converts it into data. Remote transmission valve-controlled photoelectric direct-reading water meter products comply with GB/T778.1[Measurement of water flow in closed full pipes. Drinking cold water meters and hot water meters. Part1: Specifications], CJ/T188[Data transmission technical requirements for household metering instruments], CJ/T224[Electronic remote water meter]and other standards.

Features of remote transmission valve-controlled water meter

1. Achieve pre-paid functions: meter reading, metering and deduction by day. The pre-stored funds are zero or the valve closes automatically. The charging system and meter reading control system realize intelligent management. The household meter amount is greater than 0, and the valve opens automatically;

2. No battery in the table, the power failure rate is 0;

3. Adapt to harsh environment, as long as it is not immersed in water for a long time, the remote valve-controlled photoelectric direct-reading water meter operation will not be affected;

4. When the pre-stored water fee in the table is insufficient, a method can be used to notify the user to come to pay the recharge.

5. Household meter can realize pre-paid function and post-paid function, which is flexible and convenient to use.

6. The life of remote transmission valve-controlled photoelectric direct-reading water meters is only greater than 10 years if the measurement accuracy is accurate.

7. Read the word wheel data directly, compared with the traditional pulse meter, it can reduce the reading error to zero;

8. Using low power design, only power supply is required when reading and valve opening and closing;

9. Adopting advanced data coding and verification technology, high communication reliability;

10. Adopting rotary wing type measuring structure, with high measuring accuracy, convenient meter reading, and beautiful appearance,

11. Flow performance complies with GB/T0778.1- 3- 2007 standard, accuracy level 2;

12. Compatible with multiple communication protocols; DL/T645, CJ/T188 and internal protocols;

13. Meet EMC, ESD, EMI and other electronic products’ electromagnetic compatibility design requirements, and reach industry-leading level;

14. In combination with the host computer system, a remote automatic meter reading management system is established to truly realize meter reading and monitoring automation.
