Comparison of advantages of intelligent ultrasonic water meter
In the era of lack of social energy resources and increasing energy demand, the role of flow measurement in the national economy is becoming more and more obvious. In recent decades, with the rapid development of various communication technologies and new electronic devices, micro-power and high-energy power supplies, and with the increasing maturity of high-speed digital control chips, ultrasonic flow measurement technology has made great progress. . At present, there are many manufacturers at home and abroad that develop and produce ultrasonic water meters. It is believed that the application of ultrasonic water meters will become more and more extensive.
★ Modern information management
At present, most of the water supply enterprises adopt the management mode of mechanical water meter measurement, regular manual meter reading and inspection on site. However, this model has disadvantages in metering and management. Factors such as high initial flow rate, high pressure loss and inevitable natural wear and tear of mechanical water meters lead to inaccuracy in metering; manual regular meter reading and inspection cannot find and solve water meter faults in time. problems, etc. Therefore, many urban water companies are actively building their own water resource information management systems that can automatically read meters, monitor and manage in real time, measure correctly, and calculate water sales. The ultrasonic water meter cooperates with GPRS/GSM wireless communication technology and related software to make the construction of water resources information management system more easily realized. Now
The staff of the Water Supply Department just need to sit in front of the computer in the office, and through the geographic information system (GIS) platform of the water supply pipe network, they can check the water consumption information of users in the area and the running status information of the pipe network.
Through the information displayed in real time, you can know where the water pressure is insufficient, where the pipe is prone to burst or is bursting. Through the ultrasonic water meter and the corresponding hardware software, the flow data and pressure data of the user's water meter and large meter are sent back to the information center, and displayed on the map in real time. If the instantaneous flow rate is 0L/h and the pressure is 0Pa at the monitoring point, an alarm will be automatically issued, so that the nearby water company staff can be notified in time to rush to the site for maintenance. Because of its GPS positioning function, it saves a lot of maintenance time, reduces disputes between water companies and users because they cannot find and deal with abnormal conditions in the pipe network in time, and saves a lot of water resources.
The water consumption of residents in a day is not static, there are peak and low peak periods. The ultrasonic water meter can easily determine the peak period and the low peak period. The ultrasonic water meter has the function of instantaneous flow, which can collect 4, 8 or 16 instantaneous flow or more in 1s. By collecting a large amount of flow data, and then performing statistical analysis, point data or other important data during high and low peak periods can be obtained, which can provide data support for the water company's reasonable scheduling, ensure the balance of supply and demand water pressure, and ensure the realization of its functions. convoy. Whether it is GIS, SCADA system or water supply scientific dispatching system, the premise of making these systems run stably and reliably is the support of a large amount of data, and these important data are obtained by smart water meters, and ultrasonic water meters are superior in smart water meters. Sex is prominent.
Ultrasonic water meters have the incomparable advantages of other water meters, such as small initial flow, high precision, wide turndown ratio, and easy maintenance, which all meet the new standards of modern measurement. In the modern society with the rapid development of information technology. The use of ultrasonic water meters, combined with electronic communication technology, can make a qualitative leap in the economic, social and scientific management level of the water company.
