The MERLIN CP Hemi Monitor is a compact unit designed to fit invisibly within a CP riser post. It collects Cathodic Protection (CP) data and communicates using the cellular GSM network. MERLIN CP Hemi records pipe-to-soil potentials and current levels, checks that they are within specification and reports immediately if an alarm threshold is exceeded. Alternatively it may simply be that certain measurement points on the pipeline create risks to CP technicians, such as at busy road or rail crossings, or are difficult to access, such as on private land. At these points remote monitoring is very cost-efficient and can improve safety.

Two key features of the Abriox system are:

  • Cellular telephone control, which is all that is required to set up and configure MERLIN CP Hemi monitors. This makes installation really quick and easy (typically just 20 minutes at a test post) without the need for any special equipment.
  • AC monitoring on all channels to identify a possible corrosion threat - and protect the workforce from dangerous voltages or currents.

All data is automatically transmitted in a management report to the system HQ where it is available on-line using Abriox’s MERLIN iCPSM software. ICPSM provides access from any internet-enabled PC to a passwordprotected CP database, unique to each customer.

Users can configure and control MERLIN monitors, view CP data in graphical and numerical formats or export data for further analysis and archiving.
