摘要：
A method of dispensing fluid includes three processes. A first one of theseprocesses includes pumping fluid into a resilient variable-volume dispensingchamber. The dispensing chamber is in series with a normally present finitefluid impedance and an output. The impedance is sufficient so as to causeexpansion of the dispensing chamber as it receives pumped fluid even whilesome fluid flows through the output. Another one of these processes includesrepeatedly measuring a parameter related to volume of the dispensing chamberover time. A third one of these processes includes controlling the pumping offluid based on repeated measurements of the parameter to produce a desiredfluid flow through the output. A corresponding system for dispensing fluidimplements these processes.
