SonicView: the next generation of Acoustic Gas Leak Detection System
Monitor large areas with a single sensor and without false alarms.

Keep your plant safe and running with sonic precision
SonicView is an acoustic gas leak detection system that covers large volumes with pinpoint accuracy.
Unlike traditional detectors, which wait for the gas clouds to reach the sensor, SonicView detects leaks instantly using Acoustic Leak Imaging technology (ALI). With zone-specific alerts and seamless integration into existing systems, it delivers the reliability that plant operations demand while minimizing false alarms that shut down plants unnecessarily.
From unmanned sites to complex industrial facilities, SonicView delivers 24/7 gas leak monitoring with intuitive visual confirmation of leaks of any gas type, including invisible and flammable gases like hydrogen, across vast areas.

Avoid false alerts: select critical areas to monitor, ignore others
Cover a wide area, react specifically
Distran SonicView captures gas leak ultrasounds across a 20-meter radius and a 180° angle, even outdoors and in windy conditions.
The system triggers specific actions depending on the leak's location and severity, from mailing the maintenance team for a nitrogen leak to shutting down the installation for major hydrogen leaks.
- Lower infrastructure costs: a single detector covers a 20-meter radius area
- Zone-specific response: configure different actions depending on the location and severity of the leak
- No shutting down of your plant's operations for non-critical leaks
- 2 alert levels: low for maintenance, high for safety

Set up zones to monitor, leak thresholds, and visualize leaks live from the web interface.
Alerts your way: every channel, every team
SonicView integrates seamlessly with your existing infrastructure through multiple output options, from traditional dry contacts to modern SMS notifications.
This flexibility ensures alerts reach the right people through the channels they already use, whether:
- triggering existing alarm systems (Fire and Gas system, PLC, DCS — via relays, 4-20mA or OPC-UA)
- sending direct messages to maintenance teams
- integrating with your facility's control room protocols (Web/TCP, RTSP)

Remote assessment and root cause analysis with ALI
Live & remote visual verification
When an alert triggers, operators can remotely access SonicView's visual interface to see the exact location and characteristics of the detected leak. This remote diagnostic capability allows you to assess the severity and determine whether immediate on-site intervention is required, reducing unnecessary emergency responses.
Thorough root-cause analysis
After a leak happens, SonicView lets you rewind time and replay events to see exactly what occurred when the leak started. This helps you plan corrective actions while the leaky system is offline.
