Instead of using a pump to deliver intravenous fluids in exact quantities or at precise flow rates, a simpler device may be used which only monitors the quantity and rate of fluid being infused. It usually works by counting the number or rate of drops passing through the drip chamber on the standard giving set (drip-set), and using this signal to operate a gate to stop and start the flow process. This type of controller has the advantage that the pressure applied cannot be greater than the head of the reservoir bag or bottle and so air is unlikely to be passed into the patient since there is no motive force once the infusion source is exhausted.
