Abstract
Method for detecting anomalies during the filling of a liquid metering device with a liquid to be measured out, said metering device comprising at least one suction member and at least one pressure monitoring means arranged for measuring a pressure in relation to said suction member. The detection method comprises steps consisting of: performing a prior pressure calibration of the filling of the device, calculating for a desired volume a tolerance range having an upper limit and a lower limit on the basis of the prior pressure calibration and checking whether the pressure remains within the tolerance range during the filling of the metering device with the liquid to be measured out.
