Leakplotter

Leakplotter - Methane Gas Detection Survey Solution

The Leakplotter is a vehicle conception which complies with the requirements for an economic survey in pipe distribution networks by driving above a burried gas pipeline.

The total system is designed in a modular way, and therefore practically every type of base vehicle is suitable for this purpose.

Light gases escape from a leak - funnel-shaped - within the ground and diffund through the surface as well.

While driving above the gas pipes a sample is taken and passed on to the measuring insert. As a result leakages within the spreading funnel are being indicated and recorded by the notebook.

Leakplotter FEATURES

System control

• Automatic survey of connection to measuring insert
  
• Permanent survey of pump flow and flame status of the FID
  
• Permanent survey and display of pressure inside the fuel- and test-gas bottle
  
• Automatic zero-point adjustment
  
• Automatic first ignition
  
• Manual ignition after "flame out" signal due to high gas concentration

Data collection

• Permanent record of actual speed and concentration
  
• Display of all relevant data on the main screen such as speed, concentration and alarm level
  
• Comments can be entered directly during the measurement
  
• Actual measured concentration displayed permanently

Data archive

• The viewer mode allows comparing different measurements taken
  
• Recorded data are stored in a data base for subsequent treatment
  
• Identification of measurements by location, date and controler
  
• Suitable sorting to be selected
  
• Search function is implemented

Measuring insert

• Flame-Ionisation-Detector (FID), selective for detection of hydrocarbon gases
  
• Oxidiser to eliminate disturbances caused by environmental pollution or humidity
  
• 40% hydrogen / 60% nitrogen fuel gas and 10 ppm methane / synth. air test gas bottles
  
• Bypass and water-separator for probe inlet
  
• Remote operation in case of PC breakdown
  
• Mounted into 19" rack, installed in the vehicle

Suction unit

• Suction beam with 8 bells inclusive hose connection
  
• Dust filters in every bell to avoid damage to the FID unit
  
• Additional hose filters
• Adjustable in height
• Mounted at bumper of the measuring vehicle
• Two sections to fit into the vehicle without wasting useful space
