Parameter’s leak detection system delivers on three core engineering priorities:
Pinpoint Accuracy, Rock-Solid Reliability, and Seamless Integration.
Why Choose Parameter?
Click below to learn why Parameter is the leading solution for leak detection in critical applications.
Accuracy
The Parameter RLE Leak Detection system delivers highly accurate fault detection, pinpointing events to within 0.5% for 10,000 feet of sensing cable.
Our controllers support sensitivity adjustments to minimize unwanted alerts. This lets the user set a low threshold for mission-critical areas while also allowing a higher threshold to suppress nuisance alarms from condensation. Unlike spot detectors or fixed-threshold systems, Parameter RLE distance read controllers report the exact location of fluid contact along their entire run while minimizing unwanted alarms.

Unlike spot detectors or fixed-threshold systems, Parameter RLE distance read controllers report the exact location of fluid contact along their entire run while minimizing unwanted alarms.
This enables precise mapping in distributed architectures, including subfloor, ceiling, or remote infrastructure placements. Whether the cable is 10 feet or 10,000, you’ll know exactly where a leak started. That means faster response, fewer false alarms, and greater confidence that when an alarm triggers, you know where to go and why.
Reliability
Parameter’s leak detection systems are engineered for long-term reliability, and are therefore excellent wherever false alarms and hardware failure are unacceptable. Our distance read technology is designed to minimize disruption and deliver stable performance whether you’re running sensing cable beneath raised floors, on overhead piping, in leak trays, CRACs, CRAHs, CDUs, other HVAC components or UPS systems or anywhere fluids are unwanted.
Accurate Leak Detection in High-Noise Environments
- Each controller actively filters out signal interference, delivering a stable and EMI-resistant design. This provides leak detection integrity in high-noise environments without compromising sensitivity
- With adjustable thresholds, engineers can tune the system to suppress environmental interference while still detecting small fluid events with precision.
Hardware Longevity
The hardware itself is built to last. Parameter controllers with web interfaces have no cloud dependency or subscription lock-ins. Firmware doesn’t expire, and systems don’t require periodic replacements to maintain functionality.
Some of our deployed units have been active for over 15 years. They remain fully operational, and continue to be trusted in the field.
Cables are manufactured to withstand harsh deployment conditions. From chemical-resistant and low-smoke, zero-halogen variants to rodent-resistant options for retrofit or industrial sites, the materials are selected for application-specific durability. Combined with high uptime and minimal required maintenance, Parameter systems are trusted by facilities teams who need infrastructure that works for years, not just through the next product cycle.
Integration
Our leak detection systems are designed to seamlessly integrate into the operational backbone of any facility, without compromising functionality or performance. Each controller supports multiple BMS communication protocols, including BACnet MS/TP (RS-485), BACnet IP, Modbus RTU (RS-485), Modbus TCP, and SNMP ensuring seamless integration that is never limited by legacy infrastructure or proprietary standards.
Because facilities vary widely in how they implement building management, ranging from centralized server-based platforms to distributed field networks, our systems offer flexible deployment options. Whether installed as standalone or fully networked nodes, controllers can relay status, alerts, and location data in real time to the BMS.
This allows operators to effortlessly centralize alarm management, automate facility responses, and easily track everything across floor plans, racks, or facilities—no extra middleware or translation layers are needed.
Compatible Protocols:
BACnet
ModBus
SNMP
TCP/IP
Supported Features Include:
- Support for both direct-to-BMS alerting as well as controller aggregation via master/client controller mode.
- Direct-to-BMS mapping for precise and fast leak identification and location.
- Threshold tuning to reduce false alarms in high-humidity or harsh environments
- Controllers support both latching mode (manual reset required) and non-latching mode (alert clears when cable is dry).
This combination of communication flexibility, architectural adaptability, and real-world install simplicity makes Parameter’s integration approach trusted by OEM partners and enterprise operators alike.
