ABSTRACT:
Multi-channel metering apparatus with automatic calibration, where the individual dispensing channels1, the micro-valves4of which are connected with the outlets of a distributor8, 13or15whose inlet is filled with fluid by a vessel9, 14or17thus connected, are able to be calibrated in relation to each other in that between the vessel9, 14or17and the inlet of the distributor8, 13or15a flow sensor10is arranged which for calibration during delivery of the fluid via a respective nozzle2of a respective dispensing channel1records the flow and generates signals which are respectively assigned to a defined opening time of a micro-valve4and a specific dispensing channel1and thus stored allows for individual control of the micro-valves4in order to equalize the tolerances of the dispensing channels1.
