摘要： PROBLEM TO BE SOLVED: To solve such a problem that the flow rate of gas exhausted from a detachable coupler by pressure removing operation is displayed. SOLUTION: A control circuit 29 of a gas supply device 1 has a flow rate accumulation counter 29a. The flow rate accumulation counter 29a accumulates only the flow rate that, after the flow rate obtained until gas is filled to a detachable coupler 34 is reset, a manually selector valve 43 of a car 2 is opened and gas supply to a fuel tank 3 is started, and the flow rate pulses outputted from a flow meter 24 are accumulated, then supplied to the fuel tank 3. Even if pressure removing operation is conducted after gas filling to the fuel tank 3 is finished, gas supplied to the upstream part than the manually selector valve 43 is exhausted outside, the amount of pressure removed gas is not accumulated in the flow rate accumulation counter 29a, and only the amount of gas filled in the fuel tank 3 is displayed on a display 30.

摘要： PURPOSE:To obtain a sampling device which can take out liquid by an exact amount. CONSTITUTION:A pump 5, a flow rate meter 7 and a taking-out valve 8 are arranged in a taking-out pipe 3. When operation pressure is applied by opening a solenoid valve 12, the taking-out valve 8 is switched, so that oil is poured into a sampling container 15. At the same time when sampling is started, a controller 9 counts flow rate pulses sent from the flow rate meter 7, and the constant volume of oil which is set by a constant volume setting switch 14b is poured into the sampling container 15. When pulse count value reaches a target one, a three-way solenoid valve 12 is switched to a valve closing side, so that the sampling valve 8 is closed.

摘要： PURPOSE:To prevent misconnection of an oil supply hose and to prevent unloading from a hatch of different oil type by a method wherein an oil type exclusive key corresponding to an oil type to be unloaded is taken out from a key taking-out machine and thus taken-out oil type exclusive key unlocks a tank lock for connecting an oil supply hose. CONSTITUTION:When gasoline is unloaded into an underground tank of a gas station, a driver pushes down a key selection button 19A of a gasoline hatch 2A. When the button 19A is pushed down, an engagement of a locking mechanism is released and at the same time a key taking-out mechanism corresponding to the hatch 2A is driven, so that a key 16A inserted into a key insertion port 18A is taken out. Thus taken-out key 16A from a key taking-out machine 18 is used to unlock a tank lock 15A of an underground tank and unchain a chain 25, whereby a lid 14 is opened and an oil sending hose is connected to an oil pouring port for gasoline and an oil sending port 3A of the hatch 2A.
