title: [A sterile, regulated, pulsation-dampened precision dosing system for biomedical technics].
abstract: For sterile continuous metering of small and very small flow rates delivered by peristaltic pump, a gravimetric control system which permits a high accuracy of mass flow is described. This is achieved by a digital PI controller and a digital filter with which the very accurate signal from a high precision electronic scale is filtered. In addition proposals are made for solving the problem of refilling the reservoir and for compensating the pulsations caused by the peristaltic pump.
