These methods are viable if the speed is such that the blades or key will provide the number
of pulses required at a minimum velocity of 1.5 m/minute (5 ft/minute). In applications where
exposed moving parts are required, safety shields and precautions should be applied.
Where conditions prevent the sensing of buckets, a belt pulley or paddle mounted on an
exposed shaft end, preferably the tail pulley, may be used.
