Measuring wheels
Description
When selecting a measuring wheel the kind of material to
be measured has to be taken into consideration prior to
any decision on wheel surface respectively cover lining.
The wheel circumference depends on the space available
as well as on the size of counter or encoder. The smaller
the measuring wheel, the more force required at the wheel
circumference and consequently the higher the risk of slippage and incorrect measuring results. Also the width of the
measuring wheel has an impact on the result.

Precise measuring results of a meter counter with measuring wheel depend on:
– Kind of measured material
– Contact angle
– Torque of counter or encoder
– Feeding speed
– Strain of measured material
– Surface roughness
– Contact pressure of material against measuring wheel
– Elastictiy of measured material
– Diametrical tolerance of the measuring wheel
