WHEEL DIAMETER
BOWARROW 330
BOWARROW 330 (13″) caliper calculates the wheel diameter by measuring the versine of the wheel arc encompassed between two tungsten carbide spherical points.
BOWARROW 330 is delivered with two reference wheel blocks:
Measuring length: L (TGV wheels: 70mm)
- Reference wheel blocks diameters: ØA and ØB. (Wheel diameters more often measured)
- These arcs are used to PRESET quickly your Bowarrow to a known diameter. This way allows you to enhance the gauge accuracy.
