1. A method for measuring fluid properties of a sequence of fluids, including at least a first fluid and a second fluid, comprising:
a) providing a monitoring assembly, comprising a fluid-properties measurement device that includes a resonator, and a set of resonator extensions, each one adapted to attach to said resonator in a manner such that said resonator's response to excitation is affected by immersion of said resonator extension;
b) attaching a first one of said resonator extensions to said resonator;
c) using said fluid-properties measurement device to measure at least one fluid property of said first fluid;
d) removing said first one of said resonator extensions from said resonator;
e) attaching a second one of said resonator extensions to said resonator;
f) using said fluid-properties measurement device to measure at least one fluid property of said second fluid.
