RMU1-ER: Remote Monitor for ER Probes

Description

The RMU1-ER is an ideal solution for automated remote monitoring of an ER corrosion probe which is commonly utilized to measure corrosion rates. The self-contained battery-powered device is small enough to be housed in an industry standard 3” CP test station. Measurement data is remotely accessible through an intuitive Internet web interface called corView.

Key Features

  • Low capital equipment cost and high product reliability
  • Economical fixed rate operational communication costs
  • High measurement accuracy specified over full temperature range
  • Operation in -40 to +60°C (-40 to +140°F) temperatures
  • IP65 waterproof non-submersible enclosure
  • Primary battery will last for seven to ten years (reporting plan dependent)

Features

  • Simple and very quick to install (typically under 20 minutes)
  • Measures most types of electrical resistance (ER) corrosion probes
  • Configurable ER probe geometry and thickness
  • Measures metal loss and ER probe AC & DC potential
  • Direct calculation and display of probe metal loss in mil
  • Auto-ranging measurement system provides high accuracy readings
  • Configurable alarm limits with alarm report exception transmission
  • Test station GPS position information transmitted to corView host
  • High measurement accuracy specified over full temperature range
  • Lightning and surge protected
  • Internal temperature measurement and reporting
  • 50/60Hz AC rejection for stable and accurate readings
  • True RMS AC potential measurements
  • 3½ digit wide-temperature LCD for local measurement display
  • Easy configuration using a free PC, iOS or Android application
  • Powered from a low-cost user replaceable internal battery
  • Battery will last for 7 to 10 years (reporting plan dependent)
  • Low capital equipment cost and high product reliability
  • Economical fixed rate operational communications costs
  • Satellite (RMU1ER-I) or LTE cellular (RMU1ER-G) communications
  • Small size 3.1” diameter x 4.4” (79mm diameter x 112mm) allows use within most standard CP test stations with optional cap extender
  • Optional test station cover removal alarm transmission to corView
  • IP65 waterproof non-submersible enclosure
  • Operating temperature range -40°F to +140°F (-40°C to +60°C)
