• Turn the Delrin protection cap counter clockwise and remove it from the transducer port.
• Prepare the round adapter unit: untighten the bolts (8 pieces) with the 5 mm hexagon key
(each 2 turns counter clockwise).
• Position the adapter to allow the screw thread to engage with the screw thread on the
transducer port. It may be benificial to use some lubricant (should be suitable for stainless
steel). Turn the adapter clockwise as much as possible.
• Tighten the bolts (8 pieces) with the 5 mm hexagon key.
CAUTION!
The square wedge adapter plate is available with two offset angles. For flowmeters with a
nominal size of 6", the adapter must have an offset angle of 18 degrees. For flowmeters with a
nominal size of 8" and larger, the adapter must have an offset angle of 20 degrees.
CAUTION!
Check the front face of the transducer port is free of damages or scratches. It should be smooth
and clean, otherwise there might be a risk of gas leakage when continuing with the procedure.

1 Two M5 bolts (not to be used by customer)
2 Eight M6 bolts to pull both plates to each other.
3 Four threaded holes M8 to mount the retration tool.
INFORMATION!
This should force the clearance between both plates to open to about 1 mm.
