OPW Engineered Systems supplies a complete line of Civacon brand rack monitors used in loading and unloading operations. The monitors can detect the type of sensor in the transport, the state of liquid in the tank, an overfill situation, and/or verify the grounding condition.

Many of our rack monitors offer:

• Ability to be used on systems that include many optic and thermistor sensors
• Separate output relays for overfill and ground verification
• Monitoring of overfill status with shut-down signals
