FUEL FEEDER

PROBLEM TO BE SOLVED: To make an indication of an indicator mounted on a liquid feeding nozzle legible. SOLUTION: When a predetermined time T1 passes after starting a liquid feed, an automatic valve-closing mechanism closes a valve based on a detection of a liquid level by a liquid level-detecting mechanism of the liquid feeding nozzle, and a flow velocity becomes zero. An operator operates a nozzle lever of the liquid feeding nozzle and opens the valve to conduct a finishing liquid feed to a preset value, and the flow velocity increases from zero. When a predetermined time T2 passes, the automatic valve-closing mechanism closes the valve based on the second detection of the liquid level by the liquid level-detecting mechanism of the liquid feeding nozzle, and by this the flow velocity becomes zero again. A control circuit of a measuring instrument sends indication data of a "01" indication code from a radio transmitter at the time (T1) when the automatic valve-closing mechanism closes the valve for the first time. The control part of the liquid feeding nozzle receives the indication data, and shifts the indication of the indicator of a nozzle indication unit to a magnification mode. COPYRIGHT: (C)2009,JPO&INPIT
