Abstract:
1. A supervisory Independent Secondary Shutoff Control System (system) that interfaces with at least one stream of fluid transfer in a fluid transfer facility, each stream of fluid transfer with (i) flow control device that is either an start/stop switch or a batch controller system (BCS) that includes an optional preset in communication with a meter, and a flow control valve connected to the meter; (ii) a pump and valve controller system (PVS), in communication with the BCS, the PVS with a secondary flow control valve connected to the flow control valve, a pump connected to the secondary flow control valve and to a product storage tank, and a motor control connected to the pump; (iii) a Emergency Shut Down or Emergency Fuel Shut Off circuit (ESD) connected to the PVS; (iv) a ground detection unit connected to the PVS; and (v) an overfill detection system connected to the PVS, wherein the BCS is adapted to send operation signals to the PVS and the PVS is adapted to respond to operation signals from the BCS wherein the operation signals include signals to start the pump, signals to open the secondary flow control valve, or both of these signals, the system comprising (A) a monitoring system (MS) in communication with (B) a supervisory pump and valve control system (SPVS), or (C) the ESD circuit, or both
