Abstract
In a method of determining a flow rate of a flow of a fluid of interest in a fluidic system, a raw flow rate signal (Q) is determined using a flow rate sensor. The raw flow rate signal is corrected using a flow rate correction function (Δ) to obtain a corrected flow rate signal (Q). The flow rate correction compensates for a flow rate signal error that is caused by integration of the flow rate sensor into the fluidic system. It is based on a reference correction function (δ) that is indicative of a flow rate signal error for a flow of a reference fluid due to the integration of the flow rate sensor into the fluidic system.
