FLOW METER FOR CHARGING EQUIPMENT OF GAS CONTAINER CHARGING STATION

摘要

PURPOSE: A flow meter for a charging equipment of a gas container charging station is provided to precisely measure an amount of gas supplied from a storage tank of the charging station regardless of a gas residual amount in the gas tank and conveniently check the charged gas amount by numerical display. CONSTITUTION: A flow meter for a charging equipment of a gas container charging station includes an auxiliary supply tube(12) mounted in parallel with a supply tube(120) connecting a glove valve(122) of the supply tube to a charging area(110) and artificially controlling gas supply, control valves(10) connected at both sides of the supply tube respectively behind the glove valve and in front of the charging area for controlling gas supply, a counterflow blocking valve(20) mounted behind the control valve behind the glove valve for preventing counterflow of supplied gas, a vapour liquid separator(30) connected to a bypass tube(125) for separating gas included in the gas to bypass the separated gas to a storage tank(10), a measuring part(40) for measuring gas supplied via the vapour liquid separator, a solenoid valve(50) for electronically controlling the measured gas to be supplied to the charging area, a signal recognizer for determining a signal generated from the measuring part, and displays(70) for displaying a signal applied from the recognizer.
