摘要： 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.

摘要： A method of detecting a break in a transfer line transporting a fluid product between a first vessel and a second vessel includes sensing a current pressure of fluid product associated with the transfer line. A highest sensed pressure of the fluid product is continually tracked, and a trip pressure is defined. The trip pressure increases to new multiple value(s) at any or many of a possible multiple number of times when the highest sensed pressure increases. The method further includes detecting when the current sensed pressure drops below the trip pressure to detect a break in the transfer line, via use of a pressure sensor in or in fluid communication with the transfer line. A method of automatically shutting off transfer of fluid product between a first vessel and a second vessel includes a step for shutting off the transfer of fluid product between the first vessel and the second vessel.
