ABSTRACT A device for determining the volume of spraying liquid applied to unit area of ground by spraying equipment. The device includes means for generating first and second electrical signals respectively representing the rate of supply of liquid and the ground speed of the equipment. A comparator compares the two signals and produces an output signal representing the ratio between the signals. The output signal from the comparator is applied to a meter which provides a visual indication of the output signal, this ratio representing the volume of liquid applied to unit area of the ground. An automatic speed control unit can be coupled to an output from the comparator or to the means for generating the second electrical signal. This unit is actuated by an operator when the visual indicator indicates that a predetermined supply of liquid to unit area has been achieved. The unit then maintains the ground speed at a constant value. - 1 -
