ABSTRACT:
An inexpensive fluid flow indicator capable of use in low flow conditions in a variety of environments, including but not limited to laboratory, industry, and medical applications. Flows are visually indicated by the rotation of balls loosely retained in a longitudinal passageway of the indicator's transparent housing by a flow guide and an outlet port. The flow guide imparts a circumferential or transverse direction to the axial flow of the fluid which causes the balls to revolve about the center line of the indicator.
