TRANSPORT “PASSIVE” SYSTEM AUTOMATIC LEAK DETECTION
Model # LDS 100
An automatic leak detection and shut down system designed by professional engineers specifically for LPG and Anhydrous Ammonia bulk transfer. Intrinsically safe unit continually monitors the offloading process for “rate of change” parameters signifying broken or damaged hoses, fittings and piping. A leak is instantly detected and stopped by the closure of the tank internal valve(s). The truck’s engine can also be stopped and PTO disengaged if desired. This system automatically activates at the end of each load. This ensures that the system is fully operational and helps reduce the possibility of a damaged cargo pump due to product run out. This unit also “fails safe” and closes the internal valve with a loss of power or the release of the trailer parking brakes.
An optional “Attendance Timer” is available. This query feature stops the off-loading process if the operator fails to press the “GO” button within a five minute window. A 30 second warning will sound followed by delivery shut down. This feature helps ensure operator attendance during the loading/off-loading process
