6.9 Hottap Type Drive Unit Removal
The drive unit (retractable assembly including the handwheel and screw axis) can be separated. It is beneficial
in applications where line vibration is great, or where a single drive unit is shared by multiple flowmeters.
Drive unit removal procedure
(1) Installing the shaft fitting bolts [Fig. A]
Secure the adapter A to the cover with shaft fitting bolts and hex nuts A. (This prevents the shaft from being
forced upward under line pressure.)
(2) Separating the shaft from its connection [Fig. B]
Taking off two hex nuts, turn the handwheel to extract the connecting studs from the adapter A.
(3) Removing the drive unit [Fig. C]
Taking off three hex bolts, remove the drive unit. Exercise care not to bump against the preamplifier or other
components.
Drive unit installation is the reverse of the removal instructions.
