Abstract
With the gradual development of the superior performance of the ultrasonic water meter, the use of the water meter gradually occupies most of the market due to its unique advantages. Through the analysis of the influencing factors of the ultrasonic water meter, the Kalman filter is used to analyze the influencing factors, and the differences are obtained. In this paper, combined with the application scope of the Kalman filter, it is introduced. Combined with the method of data fusion, the influencing factors of the ultrasonic water meter are analyzed. They are the flow rate, temperature, speed of sound, time difference, etc. The appropriate sensor is selected through the sensor selection method, and the corresponding data is obtained by the method of the corresponding sensor. We combine the data fusion method and use Kalman’s method to filter the data. By comparing the data before and after the processing, it is found that the data before and after the filtering of different influencing factors are small. Among them, the flow speed factor has the greatest impact on the accuracy of the ultrasonic water meter; temperature and sound velocity have little effect on the performance of the ultrasonic water meter. When designing an ultrasonic water meter, it is mainly necessary to consider the impact of flow rate and time difference on the performance of the ultrasonic water meter.
Highlights
The ultrasonic water meter is a new type of water meter that detects the time difference caused by the speed change when the ultrasonic sound beam propagates in the water upstream and downstream and analyzes and processes the water velocity to further calculate the water flow rate
This article analyzes the influencing factors of the accuracy of the ultrasonic water meter and consults relevant information to find that the influencing factors are mainly the flow rate, temperature, speed of sound, and time difference
The corresponding sensor method is used to obtain the corresponding data, and the Kalman method is used to carry out the data
Summary
The ultrasonic water meter is a new type of water meter that detects the time difference caused by the speed change when the ultrasonic sound beam propagates in the water upstream and downstream and analyzes and processes the water velocity to further calculate the water flow rate. It is characterized by a low starting flow rate, wide range ratio, high measurement accuracy, and stable work. Compared with mechanical water meters, it has the characteristics of high accuracy, good reliability, wide range ratio, long service life, no moving parts, no need to set parameters, and installation at any angle
