Hello, this is Assistant Yoo from Yoohantech.
Today, we would like to introduce a case where we installed a liquid leak detection system at a caustic soda storage facility for the Jeju fish farming cooperative.
This project was carried out for an outdoor caustic soda (NaOH) storage tank operated by the Jeju fish farming cooperative.
It has been a while since we last shared an outdoor tank leak detector installation case, so we are glad to present this project.
We recently traveled by ferry across the sea to Jeju Island.
This site is operated by a cooperative supporting aquaculture and fish farming in Jeju.
At facilities that support or directly operate seawater or freshwater aquaculture systems, such as the Jeju fish farming cooperative, caustic soda is commonly used for the following reasons.
Caustic soda (NaOH) dissolves in water and forms a strong alkaline solution, so it is used to neutralize water and raise pH levels when the acidity of aquaculture water drops below the proper range.
Caustic soda (NaOH) also provides strong cleaning and disinfection performance, making it useful for hygiene management in aquaculture facilities.
Yoohantech built an optimized leak detection system by considering both the environmental conditions around the outdoor storage tank, such as temperature and humidity, and the chemical properties of caustic soda (NaOH), especially its corrosiveness.
1. Sensor selection and placement:
2. Real-time monitoring controller (receiver panel):
Now, let’s take a look at the actual leak detector installation work.

As shown in the photos, our specialist team carried out the work carefully to maximize the completeness and long-term reliability of the system.
Rather than simply installing sensors, we also applied PVC high-piping as the connection piping for the leak detection system to ensure chemical resistance in the field.
This was a professional design decision based on the chemical characteristics of the site and the need for long-term system stability.
This is our Yoohantech specialist team working on the installation with great care.
Because the tank stores caustic soda (NaOH), PVC high-piping was used to prevent corrosion of the piping system.

As shown in the photos, the electronic leak point sensor “YHSP-SAR” was installed on the PVC high-piping system.
This sensor is specially designed to detect specific chemical leaks rather than ordinary water.
🔬 Outstanding Features of the “YHSP-SAR” Leak Detection Sensor
The main reason we selected this sensor was its excellent performance and reliability.
🛡️ Reliable even for outdoor installation
Thanks to its fully waterproof design, there is no need to worry about unnecessary false alarms caused by rain, even when tanks and piping are installed outdoors.
🌧️ It is a dependable solution you can trust in all seasons and in all weather conditions.

For this site, we installed the warning lamp type receiver “YH-100L”.
Because this was an outdoor installation, we applied a customized solution that considered both durability and visibility.
1. Protected safely in a stainless steel enclosure:
2. 105 dB high-output warning beacon:
🔋 Safety monitoring that stays on even during a power outage
Although the internal view is not fully shown here, all Yoohantech leak detector receivers include an important standard feature.
