[Leak Detector Installation] Outdoor Hydrochloric Acid (HCl) Tank at a Yeosu Power Plant | YHSP-SAR Point Sensor with No False Alarm from Rainwater

Hello, this is Assistant Yoo from Yoohantech, your industrial leak detection specialist! 👋

It is already mid-December, the final month of 2025. Even in the cold winter weather, Yoohantech continues working with full dedication to protect industrial safety across Korea.

Today’s site is a power plant located in Yeosu, Jeollanam-do. We recently completed a precision leak detection solution for the hydrochloric acid (HCl) storage tank area, which is essential for protecting boilers and turbines, the core equipment of the power plant.

💡 Tech Note: Why Is Hydrochloric Acid (HCl) Needed in a Power Plant?

Before sharing the installation details, let us briefly look at why power plants store large amounts of hydrochloric acid. The key reason is the production of ultra-pure water.

• Ion exchange resin regeneration (primary use): Boiler water in a power plant must be pure water with virtually no minerals. When the performance of ion exchange resin declines, hydrochloric acid (HCl) is used to wash and restore the resin through a regeneration process.
• Chemical cleaning of equipment: It is highly effective for removing rust and scale inside piping systems.
• Wastewater neutralization: It is also used to adjust alkaline wastewater to a neutral pH level.

📍 Leak Detector Installation Overview and Site Environment Analysis

• Site: Power plant in Yeosu, Jeollanam-do
• Target equipment: Hydrochloric acid (HCl) tank in the outdoor storage tank area
• Installation purpose: Fast initial leak detection and alarm for outdoor tank leakage
• Applied model: Electronic leak point sensor (YHSP-SAR)
• Receiver panel: 6-channel receiver (YH-200L) + outdoor stainless steel enclosure + 105 dB warning beacon
• Piping specification: Non-explosion-proof area, using GW flexible conduit

Now, let’s take a look at the actual leak detector installation photos...

✅ Thorough Pre-Inspection

Checking product condition before site deployment is the first basic step. From the moment the box is opened until the leak detector installation is completed, Yoohantech aims for zero defects.

"Site-Optimized Installation by Yoohantech Leak Detection Specialists"

Even in a harsh outdoor environment, Yoohantech’s experienced installation team works carefully to secure reliable safety. Along with installing precision leak detectors around the hydrochloric acid (HCl) tank, we also placed a receiver in a dedicated stainless steel enclosure right beside the tank so that site managers can immediately recognize and respond to emergency situations.

Safety was considered in every wire and connection. Since this area is classified as a non-explosion-proof zone, we used durable and flexible GW flexible conduit for a clean and safe finishing process.

🔬 Sensor Technology: YHSP-SAR (Electronic Leak Detection Point Sensor)

We installed the YHSP-SAR sensor at the points around the hydrochloric acid tank where leakage is most likely to occur. The reason this sensor is optimized for this site is clear.

• Target-responsive sensing: It does not react to water such as rainwater or condensation, and responds selectively only to acids, alkalis, and non-volatile organic solvents. That means no more “cry wolf” false alarms on rainy days.
• Fully waterproof design: Outdoor installation does not suffer failure from rainwater ingress.
• Easy maintenance: Its detachable structure makes installation and replacement convenient.

✅ Stainless Steel Enclosure & Leak Detector Receiver Installation for Outdoor Conditions

The biggest variable at this site was the fact that it was outdoors. The system is directly exposed to rain, wind, and sunlight.

• Stainless steel enclosure applied: We fabricated a corrosion-resistant stainless steel enclosure and mounted the receiver inside it.
• Improved on-site visibility: The receiver panel was placed near the tank so workers can immediately recognize any leak event.
• 105 dB high-output warning beacon: Considering the noisy power plant environment, we added a warning beacon that alerts danger through both visual light and a 105 dB audible siren.

✅ Core Technology: Internal Specifications of the Leak Detector Receiver (YH-200L)

Inside the receiver, the key precision-analysis modules YHSM-04S-AR and YHSM-01S-AR are installed. These modules do more than simple detection, filtering signal noise and supporting accurate situation analysis. In addition, a backup battery is built in so the system remains active even during emergency power interruptions that may occur at a power plant, maintaining continuous 24/7 monitoring.

🧪 On-Site Leak Detector Verification Test

The work does not end with installation. We proceed with testing based on real operating conditions.

• Step 1. Actual hydrochloric acid (HCl) response test: The sensor is immersed in an actual diluted hydrochloric acid solution. The receiver immediately activates a strong alarm, proving that the sensor accurately detects the target chemical.
• Step 2. Washing and reusability check: One of the strengths of the electronic YHSP-SAR sensor is reusability. After activation, the sensor can be washed with clean water and used again like new.
• Step 3. Water non-response test: After washing, we confirm that the alarm does not activate when the sensor remains wet or is immersed in water. As expected, it stays quiet. This proves in the field that the sensor does not respond to water.

🤝 User Training and Handover

After all tests are completed, we provide detailed training to the site safety manager on system operation, emergency response procedures, and sensor maintenance. User understanding is just as important as technical performance. Yoohantech’s specialists explain everything carefully and make sure even small questions are fully addressed.

The construction of the hydrochloric acid tank leak detection system at the Yeosu power plant is a strong example of Yoohantech’s technical direction: precise leak detection with no false alarms even in harsh outdoor conditions.

Yoohantech goes beyond simple product supply. We thoroughly analyze site conditions such as temperature, humidity, indoor or outdoor location, and chemical type to propose the most complete customized safety system.
