The Sensus WP-Dynamic (WPD) is a Woltmann/turbine water meter built for the measurement of high, relatively constant flow rates of cold water up to 50 °C — typically behind pumps and on trunk and bulk-supply mains. A patented hydrodynamically balanced rotor and symmetrical calibration adjustment give a high overload capability and stable accuracy, while the hermetically sealed register can be read regardless of orientation.
