Abstract:
A method for automatically shutting off a delivery system for a transfer of caustic or volatile liquids from a delivery container to a destination container when a leak occurs in the delivery system, the method comprising:a) determining if the liquid is pressurized in the delivery system; b) starting a flow of the liquid if the liquid is pressurized; c) setting a timer for a period of time to allow the flow of the liquid to reach an optimum flow rate level for a particular delivery; d) recording the optimum flow rate level on a micro controller; e) monitoring a flow rate of the liquid with a flow transducer; f) comparing the monitored flow rate of the liquid with the recorded optimum flow rate level; and g) terminating the flow of the liquid if the monitored flow rate exceeds the recorded optimum flow rate level.
