Product Models
A portable water leak detector is a handheld or compact electronic device designed to identify and locate water leaks in plumbing systems, pipelines, buildings, or industrial infrastructure. These devices typically use acoustic sensors, ultrasonic detection, moisture sensing, or pressure analysis to detect abnormal water flow or leak sounds.
Active leak detectors are systems that continuously monitor pipelines or plumbing systems using sensors such as acoustic microphones, ultrasonic sensors, or pressure analysis tools. They actively search for leaks or automatically trigger alerts and sometimes shut off water supply when a leak is detected. These systems can identify hidden leaks before visible damage occurs. Notable products include:
HL 7000 SebaKMT: Professional electro-acoustic ground microphone system used by municipal water utilities to pinpoint underground pipe leaks with high sensitivity sensors. Price range: USD 6,00010,000. Typical users: water utilities, infrastructure maintenance teams.
AQUASCAN 760T Gutermann AG: Advanced acoustic correlator that uses multiple wireless sensors to calculate the exact leak position along pipelines. Price range: USD 12,00020,000. Typical users: municipal water networks and large infrastructure operators.
SDT340 Ultrasonic Leak Detector SDT Ultrasound: Ultrasonic handheld device designed for compressed air and water leak detection in industrial systems. Price range: USD 2,000 to 4,000. Typical users: factories and industrial plants.
LeakSmart Wi-Fi Leak Detection Kit LeakSmart: Smart home system with sensors and automatic shut-off valve to prevent water damage. Price range: USD 300 to 700. Typical users: homeowners and property managers.
FloLogic System 3.5 FloLogic: Whole-house leak detection and automatic water shutoff system that monitors water flow continuously. Price range: USD 500 to 1,200. Typical users: residential buildings and insurance-driven installations.
Passive leak detectors are simple devices that detect the presence of water at a specific location using moisture or conductivity sensors. They do not actively search for leaks; instead, they trigger an alarm, LED indicator, or smartphone notification once water reaches the sensor. These devices are typically inexpensive and battery-powered. Notable products include:
Smart Leak Sensor Siemens AG: Industrial IoT sensor used in facilities and smart buildings to detect water presence and integrate with building management systems. Price range: USD 200 to 500. Typical users: commercial buildings and industrial facilities.
Honeywell Lyric Wi-Fi Leak Detector Honeywell International Inc.: Smart water sensor with temperature monitoring and mobile alerts. Price range: USD 80 to 150. Typical users: homeowners and property managers.
TECHNO-AC Leak Monitoring Sensor TECHNO-AC: Compact moisture-based leak alarm designed for industrial or utility infrastructure monitoring. Price range: USD 120300. Typical users: infrastructure maintenance teams.
Aqara Water Leak Sensor Aqara: Small Zigbee smart home water sensor that alerts users through home automation hubs. Price range: USD 20 to 40. Typical users: smart home owners.
