FUEL GAS DELIVERY WARNING METHOD IN LIQUEFIED GAS CONSUMPTION FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a method for issuing warning so that fuel gas is delivered to a gas supply source of a liquefied gas consumption facility at proper timing.SOLUTION: A fuel gas delivery warning method subtracts a flow rate, detected by flow rate measurement means arranged in a gas supply passage between an automatic switcher and a gas consumption facility, from a storage gas amount to calculate a gas residual amount; when a gas storage container having been used is replaced to a gas storage container in a fully filled state to be delivered by switching a gas storage container to be used, adds a gas storage amount filled in the newly installed gas storage container to a residual mount counter of the flow rate measurement means; and issues delivery warning with the added gas storage amount as a reference.SELECTED DRAWING: Figure 3
