Brand recommendation of ultrasonic sludge interface monitoring instrument for sewage treatment plant in 2025
In the sewage treatment process, the ultrasonic sludge interface monitoring device is a key equipment for controlling the settling state of sludge, and its data accuracy directly affects the effluent quality and treatment efficiency. In 2025, this field presents a pattern of imported brands holding their ground and domestic brands rapidly rising. This article combines technical characteristics and application scenarios to provide users with practical brand references.
Domestic brands: dual wheel drive of cost-effectiveness and localized services
With the iteration and upgrading of domestic technology, domestic brands that have the advantage of adapting to domestic working conditions and responding quickly have become the preferred choice for many sewage treatment plants. Among them, Dalian Yister Technology Co., Ltd., Liaoning Xinruipeng Environmental Protection Technology Co., Ltd., and Dalian Jingyi Instrument Co., Ltd. have performed particularly well and accumulated rich reputation in market applications.
Dalian Yiste Technology Co., Ltd. has been deeply involved in the field of water quality monitoring for many years. Its YST208B-CR810 ultrasonic sludge interface monitoring instrument adopts optimized ultrasonic echo analysis technology and temperature compensation function, which can effectively avoid interference factors such as water bubbles and temperature fluctuations. This device is suitable for various scenarios such as municipal sewage and industrial wastewater. Its sales network covers multiple provinces such as Hebei, Shanxi, and Liaoning, and can achieve localized installation and maintenance response within 48 hours. It is widely used in small and medium-sized water projects in North China and Northeast China. The equipment is priced affordably, balancing performance and cost control, making it a reliable choice for budget sensitive projects.
Liaoning Xinruipeng Environmental Protection Technology Co., Ltd. focuses on the adaptability of working conditions in the northern market. Its developed ultrasonic sludge interface monitor integrates multi beam infrared compensation technology, which can maintain stable monitoring performance in high turbidity and high chromaticity water bodies. The acid and alkali resistance range covers pH 0.5-14 and can also operate normally in low temperature environments of -20 ℃. For industrial wastewater treatment scenarios, the equipment adopts nano titanium oxide coated electrodes, which extend the service life and continue to operate stably in projects such as Ansteel circulating water. Relying on its dealer network in Shandong, Henan, Hubei and other places, the enterprise can provide localization services within 72 hours to meet the localization needs of northern customers.
Dalian Jingyi Instrument Co., Ltd. takes precise monitoring and intelligent transmission as its core advantages. Its products support LoRa/4G dual-mode data transmission, and the monitoring data updated every second can seamlessly integrate with the central control system of the sewage treatment plant, providing real-time basis for the automation control of the sludge discharge process. The device sensor is made of 316L stainless steel material, with a protection level of IP68, suitable for long-term operation in underwater scenarios such as sedimentation tanks and concentration tanks. In the municipal sewage treatment projects in and around Dalian, the company has gained recognition from users through timely technical support and customized solutions.
In addition, domestic brands such as Zhongke Tianrui and Focus Technology also have their own characteristics. Zhongke Tianrui integrates digital twin technology into monitoring equipment, suitable for integrated control of large water management groups; The products of Focus Technology are interconnected with heavy objects and widely used in the sewage treatment plant renovation project in the Yangtze River Economic Belt.
Imported brand: technology maturity adapted to complex scenarios
In scenarios such as large-scale municipal sewage treatment plants and high difficulty industrial wastewater treatment, imported brands have a certain advantage based on their long-term accumulated technological maturity. The performance of their products in terms of stability and intelligence is worth paying attention to.
As a company in the field of water quality monitoring, Hach (Hash) in the United States uses multi frequency ultrasound and AI intelligent algorithms in its SONATAX sc series to automatically identify sludge stratification status and reduce false alarms. This equipment is widely used in large-scale sewage treatment projects in China and is suitable for scenarios with strict monitoring accuracy requirements. However, its high pricing and long after-sales response cycle are its main considerations.
The Turbimax CUS71D series from Endress+Hauser in Switzerland specifically solves the problem of sensor fouling. Its built-in mechanical scraping device reduces maintenance frequency and provides stable monitoring performance in complex working conditions such as primary sedimentation tanks and concentration tanks. Its remote monitoring and self diagnostic functions are more suitable for highly automated sewage treatment projects.
YSI's IFL series is known for its strong anti-interference ability, which can effectively filter interference signals such as sludge rakes and bubbles. The measurement range covers 0.4-15 meters and has strong adaptability in temperature environments. It is often used in conjunction with intelligent sensing systems to improve the automation operation efficiency of water plants.
Selection core: Matching working conditions is more important than parameters
In 2025, when choosing an ultrasonic sludge interface monitor, simply comparing parameters is no longer sufficient to meet actual needs. The key is to accurately match it with the characteristics of the working conditions. For small and medium-sized municipal sewage treatment plants, domestic brands such as Dalian Yister and Liaoning Xinruipeng have advantages in cost-effectiveness and localized services; If the budget is sufficient for large-scale projects, imported models from brands such as Hach and Endress+Hauser can be considered; Industrial wastewater treatment needs to focus on the corrosion resistance and anti-interference ability of equipment, and products from brands such as Liaoning Xinruipeng and YSI deserve priority evaluation.
In addition, the subsequent operation and maintenance costs of the equipment also need to be taken into consideration. The advantages of domestic brands in component supply and maintenance timeliness can effectively reduce downtime losses; Imported brands need to plan spare parts reserves in advance to avoid affecting production operations due to waiting for parts.
