DRAM™

Distant Reading Acquisition Module

Distant Reading Acquisition Module provides pipeline operators and those responsible for the protection of large structures, with a means of remotely monitoring many security and integrity sensors at distances of up to 5 kms over a single twisted pair cable.

WJEC is able to supply instrumentation packages comprising of:

  • Uniaxial weldable strain gauges with water resistant cabling
     
  • Weldable thermocouple with water resistant cabling
     
  • Data acquisition and conditioning units housed in water resistant enclosures
     
  • High strength assembly mounting fixture used to secure all components to the pipe
     
  • Central processor units housed in water resistant enclosures
     
  • Interconnect cabling designed to transmit power and serial communication between the central processor units and the data acquisition and conditioning units.
Pipelines, in many parts of the world, cross unconsolidated deposits. This unstable material may be weak and water bearing. Structural integrity problems are particularly serious where river crossings are involved due to the undercutting effect on slope by continuous hydraulic erosion, and in regions subject to seismic risk and the resultant slope instability. The downslope soil movement causes the development of tension and compression traction forces on the upper and lower pipeline sections.
 
Weir-Jones Engineering Consultants introduces its Distant Reading Acquisition Module ( DRAM™) to provide comprehensive field-deployed data acquisition and robust storage capabilities. DRAM™ enables pipeline operators to detect even the slightest deformation of a pipe caused by the movement of the surrounding soil. Installed directly onto pipelines, the sensor elements gather strain, displacement, tilt, and pore pressure data which, when combined with broader environmental data collected via other sensors, presents a comprehensive and highly accurate real-time picture of the pipeline’s state-of-health.
