Truck Loading Overfill Prevention / Ground Verification Controller

Truck Loading Overfill Prevention and Ground Verification Controller

At Assentech Sales Limited, we are proud to offer the OPW Model 3205E ROM (Retain Overfill Monitoring) system. This advanced secondary overfill prevention solution is designed specifically for tank truck loading operations. The system not only monitors retained product, but also provides indicators for wet/dry conditions, wire short cuts, grounding conditions, and shorted sensors, using LED indicators and a separate display for clear and immediate status updates.

Since the shift from top to bottom loading in the early 1980s, ‘rack’ monitors like the OPW Model 3205E ROM have become commonplace in tank loading bays around the world. This transition to bottom loading has revolutionised safety levels during tanker filling by eliminating the risks associated with working at height, exposure to volatile organic compounds (VOCs), and flashover. The term ‘rack monitor’ is a general term for ground verification overfill monitors that are designed to comply with EN 13922 standards. As a trusted intermediary, we ensure you receive this high-quality equipment to enhance the safety and efficiency of your operations.
