ROM III Monitor

ROM III On-Board Monitor

Companies involved in the transportation and handling of hazardous bulk commodities rely on real world safeguarding against costly overfills every day and they rely on Civacon to provide it. The ROM™ III Overfill Detection Monitor is manufactured to deliver years of worry-free performance under the most rigorous conditions.

The ROM™ III, in the same small and lightweight housing footprint as the ROM II, adds two additional compartments (up to 8-total), while retaining the same straightforward layout and operation. Plus includes new enhanced features to address today’s market needs. This new unit has internationally safety approvals to North American, IECEx and ATEX standards; plus works on both 12v and 24v systems and can monitor up to eight compartments of 2-wire overfill detection and retained product sensors.

The ROM™ III continues to offer the industry standard socket outputs for 2-wire (green) “thermistor” sockets, 5-wire (blue) "optic" sockets as well as a “float” Loading Rack relay output. Still featured is our unique three separate, AUX inputs for additional tanker loading safety interlocks. Plus, new to the ROM™ III is a dedicated NON I.S. relay output to control an on-truck pump, control valve, PTO, etc.

The ROM™ III Onboard Monitor has been designed for use with any Civacon 2-wire overfill sensor.
