Jiwei 80GHz Radar Level Transmitter: Digital Level Measurement for Dairy Storage Tanks

Introduction: Digital Challenges in Dairy Processing, Storage, and Transportation

In the modern food industry, especially in dairy manufacturing, the continuity of the production process and the precision of material management directly determine the ultimate quality consistency of the products. For large dairy plants, every step from raw milk reception and standardized blending to buffering before finished product filling highly depends on the stable operation of various stainless steel storage tanks.

In a large dairy enterprise in Inner Mongolia, which operates 11 fully automated production lines, the daily processing capacity is massive. The factory features widely distributed stainless steel tank clusters used to store dairy products at different stages, concentrated auxiliary materials, and process water generated during system operation. In the past, due to the lack of highly reliable continuous level monitoring methods, the enterprise often faced tank overflow risks or material shortage downtimes caused by inaccurate manual measurement.

Taking the digital upgrade of this dairy plant as the background, this article will focus on exploring how the JWrada®-34 80 GHz high-frequency radar level transmitter, independently developed by Jiwei Automation, achieves precise and intelligent digital transformation of level monitoring in stainless steel tank clusters for dairy production through its leading physical characteristics and smart connection technology.

Analysis of Traditional Pain Points in Dairy Storage Tank Level Measurement

At the dairy production site, level measurement in stainless steel tanks is by no means an easy task. Before introducing the JWrada®-34, the dairy plant was plagued by the following types of problems for a long time:

1. Interference of Complex Process Environments on Measurement StabilityIn the dairy processing process, the internal environment of stainless steel storage tanks is exceptionally complex:High Temperature and Steam: After raw milk is heat-treated or sterilized, it enters the storage tank, generating a large amount of steam inside. This causes traditional ultrasonic level transmitters to frequently lose accuracy due to sound wave obstruction.Liquid Level Fluctuation and Foam: High-speed stirring processes cause violent liquid level fluctuations or even foaming. Traditional hydrostatic sensors struggle to distinguish the true height.Condensation Phenomenon: The temperature difference between the stainless steel tank wall and the top roof often causes condensation on the sensor surface, interfering with signal emission.
2. Inefficiency and Errors of Manual InspectionWithin the massive 140,000-square-foot plant area, relying on manual observation through sight glasses or manual inventory not only consumes a vast amount of human resources but also presents significant data lag. For critical auxiliary material tanks, manual recording errors often lead to deviations in formula proportions, thereby affecting product taste and qualification rates.
3. Physical Limitations of Installation and MaintenanceDairy storage tanks are usually compactly designed, leaving limited installation space on the tank roof. Internally, there are often welded mixing blades, heating/cooling coils, and feed spray balls. Due to their wide beam angles, traditional low-frequency radars emit microwave signals that easily hit these internal components, generating false echoes and causing the instrument display to jump or even crash.

Core Selection Logic – Why 80 GHz Narrow Beam Technology?

Addressing the particularities of the dairy production process, upgrading the level measurement technology from traditional contact-type or low-frequency radar to 80 GHz high-frequency narrow beam radar is a technological necessity for achieving industrial automation.

1. Narrow Beam: The “Scalpel” to Evade Complex InternalsJWrada®-34 adopts advanced high-frequency signal processing technology, with a beam angle of only 3 degrees. In dairy stainless steel storage tanks, this 3-degree narrow beam acts like a precise scalpel, capable of passing through narrow installation positions on the tank roof, perfectly bypassing mixing shafts and coils, and directly targeting the material liquid level. This characteristic solves the long-standing problem of radar level transmitters losing accuracy due to “misreading” internals.
2. 80 GHz: The Physical Advantage of Penetrating Steam and CondensationThe higher the frequency of the microwave signal, the stronger its anti-interference capability and measurement accuracy. The 80 GHz high-frequency microwave has extremely strong penetrating power in the high-humidity environment inside stainless steel storage tanks. Even with slight foam on the liquid surface, the high-frequency signal can still capture the true liquid level reflection wave, ensuring the accuracy of level data during continuous dairy production.

Technological Depth of JWrada®-34 Radar Level Transmitter and the Advantages of Domestic Substitution

As the only national brand in the Chinese market capable of competing head-on with international giants like VEGA, the widespread application of Jiwei JWrada®-34 in the dairy industry marks the rise of domestic sensors in the high-end sector.

1. Jiwei Smart Control APP: Opening a New Dimension of Bluetooth DebuggingJWrada®-34 features a built-in industrial-grade Bluetooth communication module. In complex dairy workshops, engineers no longer need to climb to the tank roof for tedious button operations. Through the Jiwei Smart Control APP, Chinese technicians can extract the instrument’s echo curve in real-time from a safe ground area. This intelligent interaction method significantly improves the safety factor of on-site maintenance.
2. “Fast-Paced” Deployment: 2-5 Minutes for Parameter Setting with MaterialsUnder the high-frequency alternating production rhythm of dairy plants, equipment debugging cannot take up too much time. JWrada®-34 supports parameter setting while materials are present. Even if the storage tank currently holds dairy products or additives, through the algorithm compensation within the APP, the parameter setting for each device takes only 2 to 5 minutes. Furthermore, for similar tank clusters, the system supports one-click parameter copying, greatly shortening the integration cycle of the entire plant system.
3. Hardware Dual Control: Reliable Guarantee of LCD Screen and Physical ButtonsJiwei does not blindly pursue sole wirelessization but retains a high-brightness LCD screen and industrial-grade physical buttons on the instrument body itself. In certain special areas or signal blind spots where mobile terminals cannot be used, this fully manual control mode provides a baseline guarantee, ensuring that level monitoring never goes offline.

In-depth Analysis of Application Examples in Dairy Storage and Transportation Scenarios

In the actual transformation of this Heilongjiang dairy plant, we widely applied the JWrada®-34 to the following two core storage tank scenarios:

Scenario 1: Raw Milk Storage and Standardized Blending Stainless Steel Tanks

Working Condition Difficulties: Large tank volume, frequent material entry and exit, accompanied by continuous low-speed stirring.

Application Performance: JWrada®-34 utilizes its 3-degree ultra-narrow beam to perfectly avoid mixing shaft interference. Its high-frequency continuous measurement characteristic (multiple signal refreshes per second) reflects minute fluctuations of the liquid level in real-time, providing an accurate volume base for subsequent standardized blending.

Scenario 2: Production Process Condensate Recovery Stainless Steel Tanks

Working Condition Difficulties: The temperature inside the tank reaches up to 95 degrees Celsius, representing a typical high-temperature, high-humidity, and condensation-prone working environment.

Application Performance: The 80 GHz signal is completely unaffected by temperature and humidity fluctuations. Through remote settings via the APP, Chinese engineers quickly completed signal shielding processing for the condensation water on the tank roof, achieving all-weather monitoring of the condensate level in extreme environments.

Core Competitiveness Benchmarked Against International Brands (VEGA)

For a long time, the radar level transmitter procurement lists of global high-end dairy enterprises have been monopolized by foreign multinational companies, with international giants like VEGA dominating the level monitoring of core stainless steel tank clusters. Because dairy processing has almost rigorous requirements for hygiene levels, anti-interference capabilities, and measurement accuracy, it was difficult for domestic brands to penetrate this high-end market in the past. However, the emergence of the Jiwei JWrada® series radar level transmitters, relying on hard-core strength comparable to first-tier international brands, has completely broken this passive foreign monopoly pattern, becoming the only iconic product in the Chinese market capable of competing head-on with VEGA and achieving domestic substitution in benchmark projects.

In terms of equivalence in technical parameters, the JWrada®-34 already fully possesses the hard strength to keep pace with top-tier international brands. Its 3-degree ultra-narrow beam angle control technology can precisely avoid complex mixing shafts, coils, and feed spray balls inside dairy storage tanks like a scalpel, solving the long-standing signal jump problem caused by low-frequency radars misreading internal components. At the same time, the device features a built-in advanced dynamic echo filtering algorithm. Even when facing violent liquid level fluctuations caused by dairy stirring, as well as severe volatile gases and condensation generated under high-temperature and high-humidity conditions, it can still accurately capture the true material liquid level. Its extremely short dynamic response time further guarantees the real-time nature and continuity of data refreshing during raw milk storage and standardized blending, achieving comprehensive benchmarking against multinational brands in core physical indicators.

In terms of localization of the software ecosystem and intelligent interaction, Jiwei demonstrates agility and service response speed that foreign brands can hardly match. The “Jiwei Smart Control APP,” deeply customized for the operational and logical habits of Chinese engineers, features an intuitive and friendly all-Chinese interface, completely bidding farewell to the tedious and obscure menu hierarchies of foreign instruments. Through seamless connection via an industrial-grade Bluetooth chip, technicians can complete remote real-time debugging, echo curve viewing, and seamless software upgrades of tank-roof instruments from safe ground areas. It is particularly worth mentioning that its unique one-click parameter copying function allows engineers, after debugging the first device, to send the complete configuration in batches to the remaining multiple devices with the same working conditions, without needing to input them repeatedly device by device. This deployment efficiency in large-scale multi-line centralized projects is significantly superior to the slow-iterating general software of foreign brands.

Furthermore, extremely high cost-effectiveness and deep customization capabilities endow Jiwei with a natural competitive advantage in the local market. The dairy industry has extremely strict hygiene chuck or flange interface standards. Foreign giants often only provide standardized specifications, with long customization cycles and high prices. In contrast, Jiwei not only provides highly cost-effective system solutions but can also quickly offer customized sanitary interfaces and material matching based on the specific process installation needs of the dairy plant. Regarding subsequent maintenance costs, spare parts supply, and on-site technical support for Chinese engineers, Jiwei relies on a localized supply chain to show efficiency and service elasticity unmatched by multinational companies, truly allowing enterprises to significantly reduce comprehensive operating costs without sacrificing measurement quality.

Full-Process Revenue Assessment After Digital Transformation

By comprehensively deploying JWrada®-34 radar level transmitters across 11 production lines, the dairy plant has achieved a leap from “experience management” to “data management.”

1. Intuitive Improvement in Operational Efficiency and ROIPrecise continuous level measurement data is directly integrated into the factory’s DCS control system. Management can monitor the incoming and outgoing balance of each batch of dairy products in real-time, reducing auxiliary material waste and bringing the tank overflow risk to zero. This shift to automation directly shortens the Return on Investment (ROI) cycle and improves overall operating gross margins.
2. Structural Adjustment of ProductivityAutomated monitoring completely frees up the labor force previously engaged in repetitive inspection work. Because the JWrada®-34 is equipped with a Bluetooth remote diagnostic function, maintenance costs have been reduced by over 40%, allowing technicians to focus their energy on more complex process optimization and quality control.
