Installation
5. Verify the sensor tip made contact with the pipe wall by removing the pipe and
ensuring that some of the marker has been rubbed off. For special-cleaned Annubar
sensors, look for wear marks on the tip. If the tip did not touch the wall, verify pipe
dimensions and the height of mounting body from the outer diameter of the pipe and
re-insert.
6. Align the flow arrow with the direction of flow. Re-insert the flowmeter into the Pak-Lok
body and install the first packing ring on the sensor between the lock ring and the
packing follower. Take care not to damage the split packing rings.
7. Push the packing ring into the Pak-Lok body and against the weld lock ring. Repeat this
process for the two remaining rings, alternating the location of the packing ring split by
180°.
