The Pygmy Current Meter is a versatile instrument with a long history of accuracy, reliability, and durability. The precisely balanced Bucket Wheel mounts on a vertical pivot inside a yoke and rotates by water flow. Each rotation of the Bucket Wheel produces an audible click which users monitor either manually with a headset or with digital equipment. Rotation rate is proportional to water velocity. The meter measures streamflow velocities from 0.1 to 25 feet per second (0.03 to 7.6 meters per second).
Users suspend the meter by a wading rod while wading a stream. Use a Pygmy Current Meter for shallow, slow, wading survey applications.
