Abstract

The invention relates to a flow meter and in particular to a flow meter suitable for connection into a fluid conduit. There is provided a flow meter (1) having an inlet (2) and an outlet (3) for connection into a fluid line and comprising interconnected cylinders (10, 20, 30) each cylinder having a plurality of ports (11-17, 21-27, 31-37) controlled by a piston (100. 200, 300) axially-movable therein such that at any time the inlet and outlet are in fluid communication by a fluid pathway which includes two cylinders characterised in that there are three interconnected cylinders (10, 20, 30).
