Water metering is a relatively new field. Modern water meters were invented in the middle of the 19th century and were widely used only more than 100 years ago. Since then, water metering technology has been greatly improved and will continue to do so. Let us look at the development of water meters and the benefits of each technical improvement.
Manual water meter reading：
If you are of a certain age, you may remember that the instrument crew walked by your neighbor every two or three months. He would walk to each house, look at the water meter, and write the numbers on the notepad. Then, the information must be summarized and analyzed in the municipal department.
Although the use of computer technology has greatly improved the efficiency of this process, the shortcomings of this method are obvious. It is expensive and time-consuming, and there are real human errors.
Walking water metering：
The first major technical improvement of the manual reading device came from the invention of the handheld device. The device allows the meter reader to download information by simply touching the device to the meter without having to open and read each meter separately. This not only saves considerable time and labor costs, but also improves the accuracy of readings.
AMR and autonomous driving metering：
With the invention of AMR (Advanced Meter Reading) technology, meter readers no longer have to walk on the street. The information of each meter is transmitted wirelessly every few seconds, and can be accessed within a short distance, so that the meter reader can easily drive and collect data through the transceiver in the vehicle. Then download the information to the CIS software and then from there to the billing software, which will generate an invoice.
At present, AMR is still the best-selling water metering technology on the market. However, it does have some obvious disadvantages. Since the data transmission from the AMR unit is short distance, the vehicle still needs to be deployed. This increases the cost and environmental impact of metering, and limits the frequency with which readings are actually taken. In addition, it is common to lose some readings for each route. At the end of the day, the meter reader must return and manually collect information from those unreported meters.
Advanced Metering Infrastructure (AMI)：
The latest water metering technology eliminates actual visits to the metering community. With the remote data transmission function of AMI technology, data can now be automatically collected directly from ½ to 5 miles. This has revolutionary significance. AMI makes readings more frequent, for example once every hour or even 15 minutes apart. This will provide a more detailed picture of water usage and help water companies quickly locate and resolve leaks that have not been discovered in the past weeks or months.
AMI can improve communication with customers to solve water problems. Its intelligent software can be programmed to automatically mark abnormal usage. You can also contact customers by phone, email or SMS.
