Sensit VMD Vehicle Mounted Leak Survey Detector

he SENSIT® VMD (Vehicle Mounted Methane Detector) is a mobile leak survey solution engineered for natural gas utilities, pipeline operators, and contractors. Mounted on a vehicle's front hitch, the system enables rapid leak detection and location mapping while driving survey routes. It can serve as a primary survey tool or complement existing leak detection programs by covering targeted service areas and hard-to-access locations.

Using methane-selective infrared absorption spectroscopy, the VMD delivers highly sensitive methane detection with near-instantaneous response times. Real-time gas concentration readings are displayed on a tablet interface within the vehicle, while GPS-enabled data logging creates location-based records that streamline reporting, analysis, and leak prioritization.

Its versatile design allows installation on a variety of vehicles, including trucks, vans, ATVs, and utility vehicles, providing flexibility for urban, rural, and off-road survey operations.

Frequently Asked Questions

What does the SENSIT VMD detect?

The system is specifically designed to detect methane during natural gas leak surveys.

How sensitive is the detector?

The VMD can detect methane concentrations with a resolution of 1 PPM per meter, helping operators identify very small leaks.

Can the system be installed on different vehicles?

Yes. The detector is designed to work with vehicles equipped with a front hitch and 12VDC power and can be transferred between compatible vehicles.

Does the unit record survey data?

Yes. The system logs methane readings along with GPS coordinates, allowing users to map and analyze survey results.

How are readings viewed by the operator?

Methane concentrations and system information are displayed on a tablet connected wirelessly via Bluetooth.

Is GPS included?

Yes. The VMD includes integrated GPS with accuracy of less than 3 meters for leak location tracking and mapping.

What industries commonly use the SENSIT VMD?

Natural gas utilities, pipeline operators, leak survey contractors, municipal gas departments, and infrastructure service providers commonly use vehicle-mounted methane detection systems for leak management and compliance-related survey programs.
