In precise liquid level measurement for the chemical industry, the GUiDEPULS 62 radar level meter has become the preferred choice for project managers thanks to its outstanding performance. This article provides an in-depth analysis of the successful application cases of this product in 5 typical chemical scenarios, showing how the GUiDEPULS series (including GUiDEPULS 61/62/63/64 solid versions and 69 B solid version) solves measurement challenges under complex working conditions such as high temperatures and corrosive media, providing an authoritative reference for technical evaluation and procurement decision-making.

I. Precise Monitoring of Storage Tanks for Highly Corrosive Media

A hydrochloric acid storage tank at a large chemical enterprise originally used a float-type level meter, which suffered frequent failures due to corrosion. After being replaced with the GUiDEPULS 62 radar level meter, its PTFE antenna and 316L stainless steel housing perfectly resisted corrosion, with the measurement error remaining stable within ±2mm. Key technical advantages include:

• Using 80GHz high-frequency radar waves to effectively penetrate acid mist interference
• Built-in temperature compensation algorithm, adaptable to working conditions from -40℃~200℃
• SIL2 certified, meeting chemical industry safety standards

After project implementation, annual maintenance costs were reduced by 67%, making it a benchmark case for the GUiDEPULS series in corrosive scenarios.

II. Safety Control of High-Temperature Asphalt Storage and Transportation Systems

On the asphalt production line, the GUiDEPULS 64 solid radar level meter solved the challenge of measuring 180℃ high-temperature materials. Its unique design includes:

This solution was successfully applied to 3 ten-thousand-ton-class asphalt storage tanks, enabling liquid level interlock control and avoiding tank overflow accidents.

III. Process Optimization of Polymerization Reactors

A new materials enterprise used GUiDEPULS 63 to monitor the MMA polymerization reaction process, with its advantages reflected in:

1. Dynamic response time ＜1 second, enabling real-time tracking of reaction liquid level changes
2. Built-in foam suppression algorithm for accurate identification of the true liquid surface
3. Seamless integration with the DCS system via Modbus RTU

After project implementation, product batch stability increased by 23%, with annual added production benefits exceeding 5 million yuan.

IV. Intelligent Management of Powder Material Silos

For the measurement challenges of PE powder silos, the GUiDEPULS 69 B solid radar level meter demonstrated outstanding performance:

• 26GHz low-frequency radar waves effectively penetrate dust
• Patented waveguide tube design eliminates false echoes
• Equipped with an automatic self-cleaning probe to prevent material adhesion

After system integration, precise inventory metering was achieved, and stocktaking error was reduced from ±5% to ±0.8%.

V. Loading and Unloading Monitoring at Hazardous Chemicals Terminals

In styrene unloading vessel applications, the explosion-proof design of GUiDEPULS 61 (Ex ia IIC T6 Ga) ensures operational safety, with the main features being:

This system has been successfully deployed at 12 berths, with cumulative safe unloading exceeding 2 million tons of hazardous chemicals.

Industry Solutions and Value Summary

From the above cases, it can be seen that the key value of the GUiDEPULS series radar level meters in the chemical industry lies in:

• Improved reliability: Average trouble-free operation time ＞5 years
• Cost optimization: Overall maintenance costs reduced by 40-60%
• Safety compliance: Meets standards such as GB/T 34036-2017
