Abstract:
A cryogenic liquified gas fill station with an automatic programmable delivery cutoff for filling cryogenic liquified gas transfer tanks with a precise weighed amount of cryogenic liquified gas from a bulk cryogenic liquified gas storage tank having a liquified gas pump and a delivery hose, the liquified gas fill station comprising essentially:a support frame; a manifold with an inlet line and a bypass line connecting through a bypass regulator to a return line and an outlet line; a three-way solenoid connected to the outlet line directing a flow of liquified gas to either the return line or a delivery line having a transfer tank connector attached to the transfer tanks; and an electronic control panel connecting to a tare scale upon which the transport tank is placed, wherein the electronic control panel is programmed to deliver a programmed weight of liquified gas to the transfer tanks through the three-way solenoid and the delivery hose and then causing the three-way solenoid to shut off the flow of liquified gas to the transfer tank, diverting the flow of liquified gas to the return line.
