Water Meter

Water meters measure the volume of water passing through them and it was this product, accurate to within one percent, that made Glenfield & Kennedy famous throughout the world.   This meter has its cover removed so that the working parts can be seen.  Water coming into the meter is directed by a small valve either above or below a piston in a cylinder of known volume. The rise and fall of the piston apart from expelling the measured quantities of water also drives a counting mechanism and recording dials.  This mechanism is missing from this meter but would be viewed through a small window.
