Suitable water meter for domestic use

Volumetric Meter

Due to the volumetric rotary piston measurement principle. This meters can achieve the highest levels of reading accuracy even at the lowest flow rate.

also known as rotary piston or semi-positive displacement meters, are the most common flow measurement devices in the world and are used for almost all meter sizes up to and including 40 mm (1 1/2").

The piston meter operates on the principle of a piston rotating within a chamber of known volume. For each rotation, an amount of water passes through the piston chamber. Through a gear mechanism and, sometimes, a magnetic drive, a needle dial and odometer type display are advanced.

Most suitable water meter for domestic use.
