The ATD uses 2 microwave probes to monitor water levels in the tank. When the probe detects the emulsion layer, it signals the closing of the MOV valve on the dewatering line. Should the valve fail to close for any reason, the second probe in the tank sets off an alarm as well as triggering the closing of the MOV valve.
Tank dewatering is vital for maximizing crude oil storage and minimizing tank corrosion, but manual operations can be costly in terms of inaccuracy, manpower and environmental liabilities. The KAM ATD Automatic Tank Dewatering system ensures maximum storage efficiency without the danger of hydrocarbons contaminating the draw-off line.
Sold as a complete system or as individual units that users can connect to an existing PLC, the ATD uses two microwave probes to monitor water levels in the tank. Communicating with a PLC, the system controls an MOV (motor operated valve) on the draw off line–opening when water levels rise, and closing when the emulsion layer has descended to the bottom of the tank.
The KAM ATD probe is also unique in its solid body design, preventing the accumulation of paraffin or other contaminants on the probe which prevent the probe from accurately registering rising water levels.
