Positive displacement Water Meters

A rotary piston water meter is a high-accuracy positive displacement meter that measures water by capturing fixed volumes with a rotating piston, offering precise readings even at low flow rates.

Operating Principle

Rotary piston water meters operate on the positive displacement principle, where water enters a chamber and rotates a piston, displacing a fixed volume per revolution. Each rotation advances the register by a set amount, ensuring high accuracy and sensitivity, particularly at low and intermittent flow rates. This makes them ideal for applications where precise measurement is critical, such as residential apartments, small commercial buildings, and multi-unit complexes.
