Remote Monitoring equipment is used to monitor Cathodic Protection Systems, gathering data and providing valuable information for CP System management.

The M.C. Miller Remote Monitoring Unit provides remote monitoring and control of the Rectifier Unit. This Monitoring Unit uses GSM and GPRS to navigate & monitor corrosion around pipelines and tank structures. This enables personnel to request and collect Cathodic Protection performance information from any location around the world using cellular networks. Personnel no longer need to travel to a site, not only is this ideal in that it saves time and travel expenses but it can also be beneficial where sites are not easily accessible. The RMU does not only measure the performance of the Cathodic Protection System, it can also pick up any faults that might occur so that it can be repaired quickly.

Features
  • Request for instantaneous values for control mode and alarm
  • Request for 24hr log
  • Can operate individually or integrated with a rectifier
  • Ability to change some control settings remotely
  • 12V SLA Rechargeable battery provides up to 150 hours backup power supply
  • Transmit an SMS/Text to the master station if there is any kind of fault or tampering
  • Uses newest technology
  • Can receive instantaneous values of your cathodic protected system anywhere around the world over an SMS/Text
