A flow meter for intravenous liquids compris ing a vertical inlet passage (2), a parallel indicating chamber (9), a U shaped flow- resistant liquid passage (6), and an exit chamber ( 11). Liquid to be dispensed enters the inlet passage (2) via inlet (5) and moves down the passage to a junction with both the U shaped flow-resistant passage (6), and the indicator passage. From the junction, the liquid rises up the indicator passage to a height proportional to the flow rate set by an external flow meter, and also through the flow resistant passage, which has an outlet (8) that delivers the liquid to the exit chamber ( 11) and from there to a patient through an out let (12). The meter may be formed by an assembly of two in jection moulded components, thus reducing manufacturing costs.
