<p>There is disclosed a control apparatus for a fluid delivery system. A first input signal corresponding to a desired flow rate of fluid is input into the control apparatus. A control signal is then sent to the fluid delivery system on the basis of the input signal for the duration of a calibration test. After the test, a second input signal, corresponding to the actual flow rate obtained during the test, is input to the control apparatus. The control signal is then amended in view of the second input. Also disclosed is spraying equipment incorporating such a control apparatus. The fluid delivery system may be a pump, or may alternatively be a fluid container, having a flexible bag within a rigid box and being connected to a supply of pressurised air for forcing fluid out of the bag. <IMAGE></p> |
