Abstract
A method can include obtaining a first weight measurement of a receptacle and obtaining a second weight measurement of the receptacle. The method can further include calculating a first difference between the first weight measurement and the second weight measurement, resulting in a reference dispensation value. The method can further include obtaining dispensation data, the dispensation data including a measured dispensation value. The measured dispensation value can correspond to a quantity of a substance dispensed from the receptacle, the quantity of the substance passing through a dispensation monitor coupled to the receptacle. The method can further include calculating a second difference between the reference dispensation value and the measured dispensation value. The method can further include determining that the second difference exceeds a threshold and adjusting the dispensation monitor in response to determining that the second difference exceeds the threshold.
