The user, Shandong A New Materials Co., Ltd., is a high-tech enterprise that specializes in the production of PS series products (EPS, HIPS), polyisobutylene, and petroleum fracturing materials. To comprehensively improve the safety standards of its facility, the company launched a project to relocate and upgrade the tank area in June 2024. According to the design specifications, new level measurement instruments need to be added to the styrene tank farm. Considering that the styrene storage tank on site is a carbon steel internal floating disk tank (φ17000mm, H15500mm), and due to the poor ultrasonic propagation properties of styrene itself, the measurement signals from conventional external level gauges are weak (see Figure 1), resulting in unsatisfactory stability over long periods of use. Through research, the company got in touch with Dinghua Electronics and had in-depth discussions with its technical staff. The customer chose the next-generation energy-gathering external level gauge, whose features of strong signal strength, high precision, excellent stability, and maintenance-free operation fully met the customer’s requirements for safe, accurate, and reliable level measurement. https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/7419c07eeaec437a85a80df41edd3352~tplv-tt-shrink:640:0.image?lk3s=06827d14&traceid=2025121014553595714F244D477F2AD7F7&x-expires=2147483647&x-signature=nuCcSFWODNyzegF6%2BgL97swcROg%3D (Figure 1: Signal table for vertical styrene storage tanks) Challenge * Due to the properties of the medium, the ultrasonic echo signals are weak. * The tank is 15,500 mm high, and long-distance propagation results in weaker ultrasonic signals. * Prolonged use causes impurities deposited at the bottom of the tank to form self-polymers, which affect the reflection of ultrasonic signals. Dinghua Solution: Utilizing a next-generation energy-focused external level gauge, Dinghua’s electronic technology team formulates the solution after thoroughly understanding the client’s operational conditions and the properties of the medium involved. Energetic external level gauges are installed on all five vertical storage tanks, in combination with energetic deflectors, to enable contactless level measurement while ensuring a strong measurement signal and stable data. https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/39f6bd573fc04114824e0f24acf79da4~tplv-tt-shrink:640:0.image?lk3s=06827d14&traceid=2025121014553595714F244D477F2AD7F7&x-expires=2147483647&x-signature=ouRWoRCSgCusj3YBsz5OqmAVmjw%3D Image 2: Site of the tank area https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/d795d93676344d6b88d98a886365ec9a~tplv-tt-shrink:640:0.image?lk3s=06827d14&traceid=2025121014553595714F244D477F2AD7F7&x-expires=2147483647&x-signature=gAhDo%2FdUYsx2jdOGWCOLoXo6VZI%3D Image 3: Energy-concentrating steering device https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/a8ffdd6ae6e04b7aa4f43ad90e3e45b0~tplv-tt-shrink:640:0.image?lk3s=06827d14&traceid=2025121014553595714F244D477F2AD7F7&x-expires=2147483647&x-signature=yq7DeNRL91q6ifl7tbNw8PB2BJ8%3D Image 4: Site of instrument application. Performance of the energy-concentrating external level gauge: Signal strength increases by several dozen times (see Image 5), and the instrument operates stably. From December 2024 to February 2025, the five vertical storage tanks were successively upgraded and fed with material, and they have been operating very stably since then. https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/6b711f3a54274485a9ad664b02df8298~tplv-tt-shrink:640:0.image?lk3s=06827d14&traceid=2025121014553595714F244D477F2AD7F7&x-expires=2147483647&x-signature=aj0aKLWNND8aLVjJU4vqKGCiwck%3DFigure 5: Signal comparison chart. Customer review: “It has been very stable since it was put into use in February 2025; compared with differential pressure level gauges, it offers high accuracy, fast after-sales support, and strong professional capabilities.” ” ——Dongying New Materials Co., Ltd. https://p3-sign.toutiaoimg.com/tos-cn-i-6w9my0ksvp/9e844241840640379e7d6bf9822dcac8~tplv-tt-shrink:640:0.image?lk3s=06827d14&traceid=2025121014553595714F244D477F2AD7F7&x-expires=2147483647&x-signature=uVwtGIpW00fbCXUeN%2BPQp7XnsHY%3D Figure 6: User product usage report. It can be concluded that the energy-concentrating external level gauge provides a high signal strength and good data stability when used in styrene storage tanks; it has helped Shandong’s New Materials Co., Ltd. to achieve safe, accurate, and continuous monitoring of tank levels. Therefore, it is an ideal choice for level measurement in industries such as petroleum, chemicals, and storage and transportation.
