Advantages of concentrated-energy external level measurement products: 1- The isolated, contactless level measurement technology is highly safe and environmentally friendly. 2-Rapid online installation and debugging, thereby reducing construction costs and maintenance expenses. The 3-energy-concentrating external level gauge has a wide range of applications, features a \"zero blind zone,\" produces \"strong\" signals, and is stable and accurate. Application: Level measurement in vertical gasoline floating roof storage tanks. Customer: A certain railway transportation limited liability company. Challenge: In the customer’s initial project, the storage tanks were equipped with level gauges based on two different measurement principles – high-precision radar and servo technology. The servo-based level gauges frequently malfunctioned, forcing the maintenance team to spend a lot of time troubleshooting these issues. The customer needed a reliable and proven level measurement solution to prevent such problems from occurring again. The customer was cited in the \"On-site Inspection Opinion on the Change of the Safety Production License\" issued by the relevant authorities as having broken servo level gauges at all storage tanks in the railway loading/unloading tank farm, and was required to make corrections within a specified time frame. https://img.wanwang.xin/contents/sitefiles2057/10285453/images/173696112.png Comparison of measurement trends between the high-precision radar level gauge (red) and the servo level gauge (blue). In traditional external level gauges, the sensing elements are installed at the bottom of vertical storage tanks; over time, impurities and deposits can accumulate in such tanks, affecting the accuracy of measurements. Dinghua Solutions: Dinghua’s electronic technical support team is deeply involved, working closely with customers to understand their needs as well as the challenges they face. We recommend that customers choose the next-generation energy-concentrating external level gauge offered by Dinghua Electronics. This product is designed for harsh operating conditions such as those in vertical storage tanks. Compared to traditional external-type level gauges, it provides a significantly improved measurement signal; it can effectively overcome sediment at the bottom of the tank, reduce measurement blind spots, and offers markedly enhanced stability and accuracy. https://img.wanwang.xin/contents/sitefiles2057/10285453/images/173696114.jpg Image of the application site for the focused-type external level gauge.

Summary: With the successful implementation of reliable and proven measurement solutions, the customer has eliminated potential hazards to safe production and is able to carry out operations smoothly. The measurement accuracy and stability of the focused external level gauge are on par with those of high-precision radar gauges, as shown in the figure: a comparison of the signals from the focused external level gauge (red) and the high-precision radar level gauge (blue). Source: User usage report. After the implementation of the focused external level gauge: 1. The level signal increased significantly from 100 mV to around 1500 mV, with its intensity rising by a factor of 15. 2. Before use, the blind zone is about 1.5m ； After use, there are no blind spots. The measurement accuracy and stability have been significantly improved; liquid inlet shock, as well as the impact of liquid level fluctuations on level measurement, have been completely eliminated ； It completely eliminates the impact on level measurement caused by the gradual thickening of the sediment layer at the bottom of the tank as a result of its long-term use. https://img.wanwang.xin/contents/sitefiles2057/10285453/images/173696117.png Signal diagram of a conventional level gauge.
