Product Description

Product introduction:
The photoelectric direct reading water meter adopts the photoelectric direct reading technology to read the word wheel data, which can reduce the reading error to zero compared with the traditional pulse meter, and is an electronic remote water meter with zero error of electromechanical conversion in the automatic meter reading system.

Application Scenarios:
It is suitable for water quantity measurement in factory self-use and newly-built residential areas. It does not need continuous power supply. It reads instantaneous power supply and mechanical values. Remote monitoring and management are carried out through wired network to realize real-time data collection and monitoring, which is convenient for management personnel to master water consumption at any time.

Product features:
• High precision, stable measurement performance, small pressure loss;
• Low power consumption, stable transmission signal, long service life;
• Full range of machine IP68 protection design, long-term immersion work.

Technical advantages:
The product has been deeply cultivated for 20 years, and has the invention patent of photoelectric direct reading and the patent of semi-automatic meter reading;
High precision, directly read the dial value, the accuracy rate of 100;
