ABSTRACT:
A liquid meter with an enlarged range of indication mechanism for indicating a residual quantity provided with a fuel sender gage fitted with a float working to detect the quantity of liquid. The float has a suitable number of contacts arranged thereon to change the effective resistance values of resistors built in the fuel sender gage as the float lowers with a decrease in the quantity of liquid. The meter ranges are changed over two stages or three stages automatically and the current to a fuel meter connected to the fuel sender gage, comprising an ammeter, is controlled. Changeover of the meter ranges is indicated through a lamp to enable an enlarged indication of the residual quantity to be made.
