Types of Volumetric Rotary Piston Water Meter
Single Jet Meter
Designed for small-scale domestic water measurement, the single jet rotary piston water meter operates by directing a single stream of water onto the piston mechanism. This controlled flow causes the piston to rotate in a precise manner, allowing accurate measurement of water consumption.
Multi Jet Meter
The multi-jet rotary piston water meter improves flow distribution by introducing water through multiple inlets around the chamber. This multi-directional flow ensures even pressure on the piston, promoting smoother rotation and enhanced measurement accuracy across varying flow conditions.
Heat Meters
While not a direct variant of the rotary piston water meter, heat meters often incorporate rotary piston mechanisms to measure flow in heating and cooling systems.
Ice Prevention Meter
Designed for cold climates, ice prevention water meters are specialized rotary piston meters that incorporate temperature monitoring and flow regulation to prevent freezing in water supply lines.

• Low-Usage Systems (annual consumption < 100 m³): Perform flushing or backwashing once per year to remove sediment buildup and maintain flow dynamics.
• High-Usage or Contaminated Systems (annual consumption > 100 m³ or presence of sand/sediment): Conduct flushing every six months to prevent clogging and mechanical wear.
• Never install a non-return (check) valve downstream of the water meter, as it can create backpressure and lead to inaccurate readings or damage to the measuring mechanism.
• If chemicals (e.g., chlorine, softeners, or fertilizers) are introduced into the water downstream of the meter, ensure that all wetted parts—including the piston, chamber, and seals—are made from corrosion-resistant materials such as stainless steel or specialized polymers.
• Periodically inspect the register for fogging, condensation, or physical damage that may affect readability.
