Valve Sense

Inspection System for Leak Detection

Valve Sense

Introducing the Valve Sense mobile inspection system, the ultimate solution for efficient and precise leak detection in valves. By integrating top-of-the-line acoustic emission sensors, the cutting-edge 5G smartphone IS540.1 and the state-of-the-art Senseven software, we bring you an intuitive, automatic, and reliable leak detection tool.

This unparalleled system offers structured data management and boasts a high-quality processor for lightning-fast data processing, making it the go-to gas leak detection tool for demanding industrial environments.

The IS-VS1A.1 is powered by connecting the device to the IS540.1 smartphone.

How Does it Work? 


Four Quick Steps to Instantly Identify and

Generate a Report on Gas Leaks

Identify The Valve

Scan a Barcode, RFID tag, QR Code or enter the identifying code for the valve you wish to inspect. This enables you to maintain consistency and accountability throughout your inspection process.


Collect the aucoustic emission signals by following the step-by-step guide as to where to measure on the valve.

Instant Results

The algorithm will automatically detect whether a valve is leaking or not.

Instant Reporting

Derive further maintenance measures and create action plans based on Sensevens’ reports.
