It is a leading enterprise in the private petrochemical industry in the Northwest region, and has been recognized by the Department of Industry and Information Technology of Ningxia ** Autonomous Region as an “Industrial Leader Enterprise of the Autonomous Region” for many consecutive years. https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/4df098a635494549987fcb73a4c53c9c~tplv-tt-shrink:640:0.image?lk3s=06827d14&traceid=202512180942248D85182F346ACC43BC12&x-expires=2147483647&x-signature=lF11p1bjVFDK06DmWLSoPSZOOAg%3D Panoramic view of the tank area. Source: Customer usage report. Application of vertical internal floating disk storage tanks with methanol – liquid level measurement (φ14500mm, H14300mm). Challenge 1: To meet ** and relevant industry standards and ensure the compliance and safety of liquid level monitoring, the customer needs to install a liquid level gauge for each of the 24 vertical internal floating disk storage tanks. https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/64c0f0460e3c4eac9cf70f40d40f2d97~tplv-tt-shrink:640:0.image?lk3s=06827d14&traceid=202512180942248D85182F346ACC43BC12&x-expires=2147483647&x-signature=c%2FnsMykEtRc5T9PFMB385I9Oqcc%3D 2. The medium contained in the customer’s tank is methanol, which is volatile. This leads to the formation of a mixture of methanol vapor and air at high concentrations in the gas space above the floating level in the tank. When microwave signals from ordinary instruments pass through this gas-filled area, they experience attenuation or interference, which affects the stability and accuracy of the measurement data. 3. The customer’s system involves a floating roof tank, where the floating roof is in close contact with the liquid surface and moves up and down within the tank as the liquid level changes. Any contact instruments that need to be installed vertically on the top of the tank (such as steel strips, servos, or floats) may come into mechanical contact with the floating roof, resulting in friction or jamming, which can lead to measurement failures or damage to the floating roof, thereby affecting the accuracy of the instrument readings. 4. Radar level gauges have already been installed in the customer’s tank area; if traditional level gauges such as those based on differential pressure or magnetic flap technology are used instead, it will be necessary to make additional openings in the tank wall or install flanges and waveguides. This not only increases the costs of modification and the workload associated with the installation process, but it may also pose a risk of fluid leakage. Dinghua Solutions’ Dinghua electronic technical support team understands customer needs as well as the challenges they face. We recommend that customers choose the next-generation energy-concentrating external level gauges offered by Dinghua Electronics. Its strong signal, high stability, and maintenance-free nature fully meet customers’ requirements for safe, accurate, and reliable level measurement. The focused external level gauge is designed specifically for harsh operating conditions such as those in vertical storage tanks. Compared to traditional external level measuring instruments, 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://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/ef750fb3f929473fa0a1531b4b770abf~tplv-tt-shrink:640:0.image?lk3s=06827d14&traceid=202512180942248D85182F346ACC43BC12&x-expires=2147483647&x-signature=rIU6GAAyD95WF5eVLRVe5pj8sac%3D Installation diagram of the instrument. Source: Customer usage report. 1. Meets safety specification requirements: Two independent systems serve as backups for each other; any failure does not affect monitoring, and the signals can be integrated into the Safety Instrumented System (SIS). 2. High precision: Unaffected by changes in the gas phase of the medium, it provides continuous and stable high-precision measurements (up to ±1mm). 3. Stable and reliable: It overcomes signal interference caused by internal components (baffles, agitators) and fluctuations in the liquid level, enabling the detection of the true liquid level in complex acoustic fields and ensuring long-term stability of the data without fluctuations. 4. Achieve \"inherent safety\" with zero leakage risk: The measurement system is completely separated from hazardous materials by thick tank walls. It eliminates leakage paths structurally, representing the highest level of intrinsically safe design. In summary, the focused-energy external level gauge has now been successfully installed and calibrated, and is in official operation. Operational experience has shown that it exhibits extremely high reliability and stability: first, it enables non-contact, high-precision, real-time continuous monitoring of the methanol level inside the tank ； Secondly, it provides precise signals with a millisecond-level response for the safety interlock devices, thereby significantly enhancing the intrinsic safety level of the storage tanks ； The successful application of the focused external level gauge represents a solid step forward in tank level management toward greater intelligence and safety.

It can handle complex operating conditions; it is suitable for use in vertical dome tanks, floating roof tanks, sausage-shaped tanks, reaction towers, and other such applications. It can effectively overcome interference factors such as polymer deposits at the bottom of the tank. It can operate stably even in harsh environments with high temperatures, high pressures, strong corrosivity, high viscosity, or highly toxic substances, making it highly versatile. 2. Signal enhancement by 20-50 times: An innovative focused sonar signal director that directs the majority of the transmitted energy back toward the probe. Practical application data show an energy enhancement of at least 20-50 times, ensuring reliable and stable measurements. 3. “Zero blind zone” is achieved by utilizing Xi’an Dinghua Electronics’ patented “small blind zone technology” combined with energy-concentrating technology for blind zone compensation, thus enabling measurement without any blind zones. 4. It is more stable and reliable, capable of measuring liquids with higher viscosity; it is not affected by severe deposits at the bottom of the tank, and it can effectively reduce the impact of bubbles as well as various interfering elements inside the container on the measurement results.
