Sanchuan's brass-bodied volumetric rotary-piston meter delivers high-precision, low-flow accuracy and tamper-resistant, and ideal for residential water metering.
A rotary piston flow meter operates on the positive displacement principle:
How It Works
Fluid enters a precisely machined measuring chamber and forces a piston (or semi-rotary vane) to move or oscillate, displacing a fixed volume of fluid per cycle.
A magnet attached to the piston transmits motion through the meter body to an external register or electronic sensor.
Each revolution or oscillation corresponds to a known volume, and counting these rotations provides high-accuracy volume measurement, even at low flow rates.
Key Advantages
Exceptional low-flow accuracy—ideal for residential and precious liquid metering.
Insensitive to viscosity or turbulence, since measurement is volumetric and mechanical.
Self-stopping at zero flow; no drift or need for straight pipe runs.
