Shandong photoelectric direct reading wired remote water meter, Beijing photoelectric remote water meter, Jiangsu MBUS remote water meter, Hebei remote water meter charging system.
1、 Overview:
This series of products can be used to measure the amount of water flowing through a household or a residential unit's water pipeline. Its working mode fully complies with the metrological method. It has high reliability, strong anti-interference ability, energy-saving and durable meter reading system. The automatic meter reading system is a new remote control and billing management system designed for the water supply department. This system is divided into three layers: meters, concentrators, and terminal processors (management center). use
The communication method of MBUS bus, combined with GPRS for remote reading, realizes the automation and intelligence of water meter charging management.

2、 System diagram of photoelectric direct reading water meter
The photoelectric direct reading water meter system consists of a meter, a concentrator (capable of managing and reading 80 water meters), a computer system, and an MBUS meter reading network that does not differentiate polarity.
3、 Performance characteristics:
1. Completely solve the phenomenon of encoding errors during character wheel carry;
2. Daily work does not require power supply, only power supply during meter reading, avoiding measurement errors and extensive maintenance work caused by unstable, unreliable or faulty power supply;
3. Automatically memorize the position of the code wheel. Not pulse accumulation metering, no initialization required;
4. Digital transmission. The terminal processor can automatically verify the digits and perform error code judgment. If an error code occurs, the water meter can be requested to resend. If the error persists after multiple verifications, it will automatically prompt. So it can achieve stable, accurate, and reliable measurement in complex usage environments;
5. The mechanical reading and electronic reading remain completely consistent. There is no inconsistency in mechanical and electrical readings caused by cumulative errors or water meter reversals;
6. The sensor is non-magnetic and non-contact. There is no situation where external magnetic interference causes inaccurate readings, and the electronic reading device does not affect the measurement accuracy of the original instrument.
