Protect Your Facility with BAPI's Industry-Leading Leak Detection Systems

When it comes to water leak detection in mission-critical environments, you need more than just a simple sensor. You need a dependable, intelligent system that responds quickly and integrates seamlessly with your building automation system. That’s why we recommend BAPI’s Water Leak Detection Sensors—the gold standard in commercial leak detection.

Whether you're managing a data center, mechanical room, solar storage tank, greenhouse, or any facility with sensitive equipment and systems, BAPI provides the advanced protection and flexibility your site needs. In this article, we’ll explore why BAPI’s lineup stands above the rest, outline the sensor options available, and share real-world use cases and customer feedback.

What Makes BAPI Leak Detectors the Best Choice?

BAPI (Building Automation Products, Inc.) has a reputation for designing HVAC and automation peripherals that are reliable, easy to integrate, and purpose-built for commercial environments. Their water leak detection system is no exception.

Key Features:

• Rapid Detection: Responds to leaks in less than 5 seconds.
• Multiple Sensor Options: Choose from probe sensors, remote sensors, or rope sensors depending on the application.
• Flexible Mounting: Mount sensors to drip pans, floors, or around piping using adhesive, brackets, or screws.
• Dual SPDT Relays: Two 5 Amp output relays for integration into your BAS or alarm system.
• Manual or Auto Reset: Field-configurable reset logic makes it adaptable to your monitoring protocols.
• Durable Design: NEMA 4 (IP66) polycarbonate enclosure suitable for tough conditions.
• Universal Power: Accepts 24VAC or 24VDC with built-in isolation circuitry.
• Visual Indicators: Green power LED and red alarm LED for local status verification.
• 5-Year Warranty: Long-term reliability backed by one of the best warranties in the industry.

Sensor Types and Their Ideal Applications

• Attached Sensor - The attached sensor is integrated into the enclosure, ideal for mounting to drip pans or in small equipment cabinets. Bendable metal blades allow you to set the detection depth.
• Remote Spot Sensor - This sensor includes a 5-, 10-, or 25-foot cable and can be mounted on flat surfaces or pan rims. An adjustable depth screw provides precise detection levels.
• Rope Sensor - Perfect for wide-area coverage, rope sensors can run up to 100 feet under raised floors, around tank bases, or alongside mechanical equipment. Multiple ropes can be daisy-chained.

Sensor Combinations

BAPI systems support combining different sensor types, such as a rope sensor plus a spot detector, allowing coverage of multiple risk zones in one system.

Use Case Scenarios

1. Data Centers - Water near servers is a high-risk event. Rope sensors beneath raised floors and remote probes near HVAC equipment give full coverage and fast response.
2. Mechanical Rooms - Install attached or remote sensors beneath boilers, pumps, or chillers to instantly catch leaks or pan overflows before damage spreads.
3. Solar Hot Water Tanks - Pressure fluctuations can lead to leaks. Place rope sensors at the base of tanks and use spot detectors at connection points or valves.
4. Greenhouses - Prevent flooding and protect sensitive controls with rope sensors along the perimeter and under benches.
5. Condenser Drain Pans - Catch overflow due to clogged lines using attached or remote sensors mounted inside the pan rim.

Easy Integration with Building Automation Systems

With dual SPDT relay outputs and field-selectable settings, BAPI leak detectors easily integrate into your existing BAS, enabling automatic shutdowns, alerts, or redundancy triggers.

Customize relay logic using onboard DIP switches to:

• Select between normally open or normally closed alarm contact
• Choose relay inversion or mirrored behavior
• Configure manual or automatic reset actions

Customer Testimonials

“The rope sensor saved our entire backup room. The line failed at 2 AM and the system tripped the alarm and shut off pumps. Without it, we would’ve been underwater by morning.”
— Facilities Manager, Jacksonville, FL

“We've used BAPI leak detectors in four greenhouse installs now. Zero false alarms. Installation is quick, and they just work.”
— Mechanical Contractor, St. Louis, MO

“Very clean relay logic. Our team integrated three of these into a legacy BAS with no issues.”
— Controls Integrator, Los Angeles, CA

Maintenance and Reliability

BAPI sensors require minimal upkeep. Annual inspection and occasional cleaning are sufficient. Rope sensors can be wiped down or even cleaned in a dishwasher. Sensors are built to withstand wide environmental conditions and maintain performance in humid or dusty spaces.
