INJECTION

   Minimize
Consolidation, sealing and backfilling injection... slurry is injected into the ground according to precise technical specifications.

TYPES OF MEASUREMENT

The instrumentation on the job site simply, reliably and accurately controls, measures and records :

  • Pump control.
  • Slurry flow rate and volume.
  • Slurry pressure.

Control is based on the following criteria : pressure, GIN pressure, flow rate and volume which are fixed or vary over time.

 

THE INSTRUMENTS

The LUTIN for single pump operation. The LT3 for 2-pump operation. The BAP, the LUBAP, the DIALOG for controlling up to four pumps and the CINAUT15 for controlling up to twelve injection trains. All these instruments are constructed using particularly sturdy materials and protected by rustproof metal housings.
The DIALOG and the CINAUT can control injections with set points that vary over time.
 

THE SENSORS

Specific sensors are used to record the different parameters: the EDH for slurry flow rate and volume and the SP100 + C1650D for pressure information.

  

THE SOFTWARE

The EXPVD software is used for data application purposes; it generates and provides a simple display of the various injection parameters.
