Measuring wheels are a very cost-effective way to use rotary encoders to measure linear motion such as a cut to length applications. Measuring wheels are also useful when it is inconvenient to mount the encoder directly to the motion device. It is common to have one or two measuring wheels mounted on an encoder shaft. The two most important factors in selecting the best measuring wheel for a given application are the circumference and the surface material. The surface material must be chosen to give optimal traction without unduly compromising wear, while the circumference should be selected to give the best accuracy within the mounting constraints available.

EPC offers two types of measuring wheels in both english and metric circumferences. The first type, Faced Measuring Wheels, has a wide contact surface with a variety of faced coatings, one of which will be suitable for nearly every specialized application. The second, Rubber Insert Measuring Wheels, uses a replaceable rubber insert, or "spare tire", that is easier to set up and maintain, and fits most general-purpose requirements.
