ABSTRACT:
A linear mechanical line break detector for use on a mobile transport, the mobile transport having a supplying vessel disposed thereon for transporting a fluid product, the 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 coupled to a transfer line during transfer of fluid product under pressure from the supplying vessel to a receiving vessel, the transfer line being coupled to the receiving vessel for effecting transfer of the fluid product to the receiving vessel, includes a sensor/actuator that is in fluid communication with the transfer line for sensing the pressure of the fluid product therein. A valve actuator has a set disposition related to a set disposition pressure and has a trip disposition related to a trip disposition pressure, a selectable pressure differential being defined between the set disposition pressure and the trip disposition pressure, the valve actuator being operably coupled to the sensor/actuator for actuation thereby to the set disposition.
