Project: Plastic AA Bucket Wheels

Plastic Bucketwheel

The plastic bucket wheel is designed to be a direct replacement for the chrome plated metal wheels currently in use on the Type AA USGS velocity meter. The goals for the plastic bucket wheel are to reduce costs and to produce a more uniform bucket wheel than is currently possible with the metal version. The current design employs a plastic frame and individual cups that are made from the same mold cavity. Six cups are fixed to the frame to produce a complete bucketwheel. Being made of plastic, the bucket wheel is lighter taking less torque to begin rotation. When used with a magnetic switch head assembly, the plastic bucket wheel can very accurately measure slow velocities.
