Abstract:
A line break detector for detecting a break in a transfer line transporting a fluid product from a supplying vessel to a receiving vessel, the supplying vessel having an outlet for transferring fluid product from the supplying vessel, the flow of fluid product from the outlet being controlled by a fluid product shut off valve, the outlet being in fluid communication with the transfer line during transfer of fluid product from the supplying vessel to the receiving vessel, the transfer line being coupled to the receiving vessel for effecting transfer of the fluid product to the receiving vessel, the line break detector comprising a sensor/activator, the sensor/activator comprising at least one movable element operably couplable with the transfer line, the sensor/activator being constructed to sense a current pressure of the fluid product, to continually track a highest sensed pressure of the fluid product, and to define a trip pressure, the sensor/activator causing the trip pressure to increase when the highest sensed pressure increases, the sensor/activator being operably couplable to the fluid product shut off valve and being constructed to activate the fluid product shut off valve when the current sensed pressure drops below the trip pressure.
