Water Meter (1)

Water meters measure the volume of water passing through them and it was this product, accurate to within one percent that made Glenfield and Kennedy famous throughout the world.   The original one was designed in 1824 by Thomas Kennedy with the help of local, Kilmarnock, clockmaker, John Cameron. 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.
