Abstract
A flow meter insertable into a riser tube or an intake tube of an aquarium filter includes an insert placed in the tube and along which water flows as it is drawn by means of a power head, impeller or pump. A flow restriction arrangement, defines a flow path with respect to the insert. The insert carries an elongated slot with a scale and has two oppositely directed semi-circular flanges dimensioned so that they block water from flowing through the entire area of the container but allow the water to enter on one side of the insert, then flow into the slot and exit along the opposite side of the insert. A metering float inserted adjacent the scale and is positioned at a level height relative to the flow rate of water passing the insert. This value can be read on the scale.
