ABSTRACT:
Fluid delivery equipment comprises calibration circuitry which, in a calibration mode of operation, detects a time at which fluid is first caused to flow in the equipment, and provides an output signal a predetermined time thereafter. The output signal may be audible. The equipment is of the hand-held type, including a handset (2), incorporating a manually operable trigger (3), and a distribution head (8) connected to the handset and incorporating a manually operable variable flow restrictor.
The equipment may include means for setting a desired width of land which is to be sprayed, in which case, during a calibration mode, this desired width is used as an indicator of the desired flow rate and the predetermined time is adjusted accordingly.
