In rural areas, large-diameter water meters are often located in fields at the entrance of villages and underwater in wells. The installation locations are relatively scattered and the installation environment is relatively humid.

It is very difficult for managers to grasp the operation status and usage data of each large-diameter water meter in real time. Usually, full-time staff are assigned to visit the rural fields regularly every month to read and record the readings of each meter, and then enter them into the water management system to know the usage data and operation status of the water meters.

Large-caliber water meters in underground wells are time-consuming and laborious to read

Such scheduled on-site water readings are obviously delayed. When there are abnormal conditions such as burst pipes and water leaks, large water consumption data are usually not reflected until the next month. At the same time, leak detection lacks timeliness. Sometimes water leaks all over the floor and no one has repaired it.

With the gradual application of GPRS Internet of Things technology in the field of water meters, the above problems are solved!

We can install a GPRS transmitter on the basis of ordinary mechanical meters, and send water consumption data on a daily basis through the built-in GPRS chip. Managers can easily read the consumption data of each large-caliber water meter by sitting in the office or using a mobile phone APP.

The modified large meter has the function of automatically sending data via GPRS. Through software settings, the water consumption data can be automatically sent to the management center server at a fixed time every day. Managers can query daily water consumption data by themselves, and can also view water consumption curves over a period of time. Through usage analysis, water resource waste can be reduced and the level of scientific management can be effectively improved.

Of course, water meters installed in humid environments must pass the IP68 water immersion test, the GPRS transmitter must also be waterproof, and the GPRS antenna must have a certain length to ensure stable signal reception and transmission.
