Street Evaluating Methane Laser Assessment – SELMA Bumper

Selma Bumper - diagnostic tool for the detection of gas leakages in urban areas.

Features:

  • Unrivalled sensitivity of 0.1 ppm
  • Operates in automatic mode
  • Effective for patrolling aboveground and underground gas pipelines
  • Operates without loss of quality at a speed of up to 60 km/h
  • Ideal for monitoring underground gas storages
  • Can be mounted on any vehicle

Application/s

  • Inspection of high and low pressure gas distribution networks
  • Detects very small leakages
  • Based on a pulsed IR laser system
  • Detects leakages by utilising two independent laser detection systems: – Bumper laser for driveway leak inspection
  • GPS registration comes as standard with the SELMA system

Overview:

The SELMA Bumper is a diagnostic tool for the detection of gas in urban areas. The system detects gas leaks by simply driving down the street past the inspection area, even when maintaining a normal driving speed. With two independent laser detectors, the Selma detects leaks in front and at the side of the driving path.

The SELMA Bumper is highly sensitive and utilises a simple operation process and data assessment. It is also suitable for most vehicles.
