1. A method of calibrating a flow rate of an IV pump infusion system, comprising:
setting a flow rate for an IV pump of the IV pump infusion system;
administering medicinal fluid to the IV pump infusion system;
measuring an amount of time taken for the medicinal fluid to rise from a first position to a second position in a chamber of the IV pump infusion system via a sensor and a floating detection object, wherein the medicinal fluid exits the chamber via an outlet when the medicinal fluid fills the chamber past the second position;
calculating a flow rate of the medicinal fluid inside the chamber based on a volume of the chamber and a measured amount of time taken for the medicinal fluid to rise from the first position to the second position;
comparing the calculated flow rate of the medicinal fluid inside the chamber with the set flow rate of the IV pump; and
adjusting the IV infusion system flow rate and volume of the medicinal fluid administered by IV pump infusion system based on the comparing.
