1、 What is a large-diameter water meter
Large caliber wireless remote water meters generally work in main water supply pipelines, self owned well users, industrial and commercial users with large water consumption, and total meter measurement at the end of water supply. Therefore, the total amount of water flowing through the water meter is relatively large, which has a significant impact on users and operators. In addition, the working environment of water meters is relatively harsh, and some pipelines have significant changes in working pressure. Therefore, for large-diameter water meters, intelligent valve controlled water meters need to be carefully considered and designed.
At present, with the rapid development of communication technology, it is no longer difficult to transmit the working status of water meters over long distances. With the improvement of production processes and the application of new materials and technologies in recent years, this technology has become increasingly mature, and the failure rate has significantly decreased. Large caliber water meters generally use a single meter GPRS system for data remote transmission.

2、 Main functional features
1) Users pay first before using water;
2) Magnetic attack valve closing alarm, Chinese characters prompt alarm information;
3) Two level valve closing alarm for battery undervoltage, with Chinese characters indicating the alarm information;
4) When the remaining water level is lower than the set alarm water level, close the valve and trigger an alarm, with Chinese characters indicating the alarm information;
5) Split type handheld device LCD display, which can query the accumulated water consumption and remaining water in the table;
6) Low power design, extending the lifespan of water meters;
7) Interactive between tables and cards;
8) The water meter information is transmitted back to the management system through an IC card for easy statistics and management;
9) The protection level of the valve can reach IP68;
10) Large circulation capacity and low pressure loss.
