GAS FILLING MONITOR CONTROLLER, HIGH-PRESSURE LIQUEFIED GAS CONTAINER FOR GAS FILLING MONITOR, AND GAS FILLING MONITORING SYSTEM

摘要

PROBLEM TO BE SOLVED: To prevent over-filling in liquefied gas container and to enable filling at eaves for small-sized gas container that gas delivery has been executed by exchange of containers.;SOLUTION: A liquefied gas container 1 is provided with an ultrasonic sensor 4 for detecting liquid level, and its detection signal is put out to a gas filling monitor controller 20. When filling liquefied gas in the container 1, the controller detects that the liquid level inside the container 1 reaches a predetermined level and reports the fact or puts out a signal for directing a filling pump to stop to a tank trunk via radio. The controller 20 can be removed by a connector part 21 on the controller side, and filling work can be accomplished rationally with less cost by having a filling worker carry this controller.;COPYRIGHT: (C)2002,JPO
