| Abstract: | At present, gas medium ultrasonic water level gauge has a lower measurement precision. Through an analysis on factors affecting precision of the gauge, the article points out countermeasures for eliminating the influence factors, and a high-precision gas medium ultrasonic water level gauge is developed by using digital collection technology for analysis and compensation of ultrasonic echo frontier to improve measurement precision. The article elaborates hardware and software designs of the gauge and its disposal to interference signal. Its application at Luojiaqiao in Zhejiang illustrates that water level data collected by the gauge can meet requirements of relevant specifications, and error are within the allowable range. |
| Keywords: | high-precision ultrasonic water level gauge gas medium error analysis |
