Working Principle and Core Components of the WPD Water Meter

To understand the superior performance of the WPD Wide Range Horizontal Spiral Wing Water Meter, one must examine its core metering principle and precise structural design. As a velocity-type meter, its operation is based on fluid dynamics, converting the volume of water flowing through the meter into measurable mechanical motion.

Working Principle of the Horizontal Spiral Wing Water Meter: From Water Flow to Measurement

The operation of the WPD Wide Range Horizontal Spiral Wing Water Meter (WPD Water Meter) is based on velocity measurement. Water flows in a specific direction through the meter's internal measuring chamber, driving the rotation of the Spiral Wing impeller installed in the flow path.

Flow Drive: The meter incorporates a special flow guiding structure to ensure that the water flow impacts the vanes evenly and smoothly upon reaching the spiral wing. The higher the water velocity, the faster the spiral wing rotates.

Relationship between Speed and Flow Rate: Within the designated flow range, the rotational speed of the spiral wing is directly proportional to the instantaneous Flow Rate passing through the meter.

Mechanical Conversion and Display: The rotation of the spiral wing is transmitted to the meter's counter via a precise transmission system (typically involving a magnetic coupling or gear train). The magnetic coupling design effectively isolates the water-wetted parts from the counter, ensuring the counter remains dry and clean, and preventing scaling or debris from interfering with readings. The counter accumulates the recorded rotations and converts them into the cumulative volume (e.g., cubic meters) readable by the user.

The key to the WPD Wide Range Horizontal Spiral Wing Water Meter's ability to achieve "wide range" measurement lies in its Horizontal installation and the special geometric shape of its Spiral Wing.
