A fluid flow indicator consists of a flow chamber having a freely spinning flow rate indictor that rotates in response to fluid flow and rotates in proportion to the rate of flow. A visible indicator allows a medical practitioner to carefully control the flow rate even though the fluid flow is smooth without other visible signs of movement. In one embodiment a plurality of flow holes are provided in the fluid chamber to direct the fluid around the fluid flow indicator rotor causing the rotor to rotate in proportion to the rate of fluid flow. Another embodiment provides a flow opening to direct the fluid past the rotor. The fluid chamber is provided with a connecting nipple on either end to connect the flow indicator with a fluid delivery system.
