Common mistakes in selecting external level gauges – 80% of people make them; check it out!

With the advancement and development of non-invasive measurement technologies, as well as the convenience and economic benefits they offer, more and more users opt for non-invasive level gauges that do not require drilling holes, starting fires, or emptying the tank when measuring liquid levels in tank areas (also known as sonar-based non-invasive level gauges, external-mounted level gauges, or non-invasive ultrasonic level gauges). Faced with the large number of manufacturers of such non-invasive level gauges available on the market, users often feel confused about which one to choose Which one to choose? As the inventor of external level gauges with 25 years of field experience, I’ll guide you all in conducting an analysis. Does more functionality lead to more accurate measurements? The measurement range of external level gauges is between 0.1 and 30 meters. Different models are available for various measurement ranges; for example, in the case of large spherical tanks where high measurement stability is required, the CE type of gauge, which is capable of handling strong level signal variations, is chosen ； For small horizontal tanks with a measurement range of a few meters, higher precision is required. In such cases, high-precision CE and PE type gauges are more suitable. Moreover, since different models have different focuses and slightly varying design approaches, it is necessary to choose the appropriate model based on specific requirements in order to meet the measurement needs to the best possible extent; it’s not sufficient to simply pursue products with as many functions as possible. Some features are not very useful for your measurement needs; for example, with smartphones, the functions we use most often are just making calls and using WeChat. For products based on the same principle, aren’t the differences minimal? In terms of their working principle, they are identical – all use ultrasonic waves to measure liquid levels from outside the tank wall, enabling continuous level detection. However, there are significant differences beyond that; factors such as product quality, the stability of measurements, the reliability of the instrument’s signal processing technology, and the manufacturer’s after-sales service all vary from one product to another. The most crucial technology in external level measurement is the ability to analyze level signals. Dinghua Company’s external level gauges utilize advanced \"micro-vibration analysis\" techniques for processing acoustic signals from such measurements. These techniques stem from over ten thousand units of external level gauges, hundreds of different operating conditions, as well as more than 20 years of data collected from industrial sites. Through in-depth analysis of this data, sophisticated capabilities for analyzing level signals and calculating levels have been developed. The software is continuously upgraded to ensure that the reliability and stability of these external level gauges remain at the highest level. Do high product prices mean good quality? As the saying goes, you get what you pay for. The harms of winning bids at the lowest price are something we truly despise! Just because the price is high doesn’t mean the quality is good; it can’t be generalized – it depends on the product type. But this is the case for external level gauges used in industrial instruments. There’s a saying: You feel pain when buying an expensive item, but the excellent experience that comes from its high quality, performance, and service is incomparable ； You buy something cheap, and it doesn’t hurt at the time, but once you start using it, you have to deal with the problems caused by its poor quality. These problems persist until you decide to replace it, and it requires great mental strength to endure them! It’s like the difference between Mercedes and Zotye (a knockoff sedan).
