Abstract
A flow meter comprises an inflow chamber having a first fluid inlet, an outflow chamber housed in the inflow chamber and having a second fluid inlet, which is in fluid communication with the inflow chamber, and a fluid outlet by which fluid can drain from the outflow chamber, and a sensing device having a elongate sensor which is positioned at, or adjacent to and downstream of, the second fluid inlet. The second fluid inlet is of limited dimensions so that, in use, a head of fluid is formed in the inflow chamber and the flow rate of the fluid passing through the second fluid inlet is monitored based on the extent of the elongate sensor which is covered by the fluid.
