1. An integrated intravenous (IV) administration set, comprising:
a flow stop comprising a tubing fitment and a housing, the flow stop configured, in a first position, to prevent a flow of a fluid through a tubing, and in a second position, to permit the flow of the fluid through the tubing, the tubing fitment comprising a protrusion configured to receive a tubing;
an electronic flow sensor disposed within the housing, the electronic flow sensor configured to measure the flow of the fluid in the tubing; and
one or more conductive connections configured within the housing and configured to provide electrical power to the electronic flow sensor; wherein the flow stop is shaped to be loaded and engaged to a receptacle of an infusion device, and shaped to cause, when loaded and engaged, the one or more conductive connections to engage with a corresponding conductive connection provided by the infusion device to activate the electronic flow sensor based on a power flow from the infusion device.
