Accuracy estimations of testing of infusion devices using weighing balances.
The role of gravimetric balances in the evaluation of infusion devices is considered from a perspective of accuracy for such evaluations and the actual physical and interface characteristics of such balances as specialist measurement devices. In particular, the dynamic properties of weighing balances are discussed in relation to observations of variation of response times and stability settings. This work has identified characteristics, which may influence flow measurement techniques as defined by measurement protocols adopted by relevant standards and those developed independently. While a dominant error is introduced due to balance resolution error, consideration of timing errors associated with data capture is also essential.
