Overflow prevention system and method using laminar-to-turbulent flow transition

摘要: An overflow prevention system and method for storage tanks includes a flow disturber situated in the tank fill tube, fluid level sensor sensing tank, an actuator that causes to move toward tube inlet response rising sensed by sensor. The is arranged travel between first position which it does not cause turbulent second flow. responsive when predetermined reached. transition triggers automatic shut-off feature of dispensing nozzle prevent from being filled beyond level.
