Software developed for the Gas Distribution NetworkOperator(DNO)
PROSoft integrates with the METREX
DNO’s using these instruments can acquire the following data

  • Data linked by time
  • Geographic location
  • Detected gas levels

Visualise Hard Data
Customisable graphical view of leak detection surveys where the recorded data are shown overlaid on Open Street Map views. DNO digital cartographies can easily be overlaid

  • Detailed street views
  • Locations of pipe network
  • GPS points surveyed

Operators can visualise their complete survey and see where leaks occur relative to gas infrastructure and plan.

Realtime Connection and Communication
Data exported into various spatial formats, KMZ, ESRI & .shp
