1. A system comprising:
a peristaltic pump comprising:
a plunger configured to move relative to a tube;
a spring configured to bias the plunger toward the tube;
an actuator configured to cause the plunger to move away from the tube, wherein the actuator is further configured to disengage from the plunger;
a position sensor configured to sense a position of the plunger; and
a processor configured to estimate fluid flow within the tube using the position sensor; and
a monitoring client configured to control fluid flow of the peristaltic pump.
