6. Apply proper thread sealant to the tapered pipe thread on the compression fitting and secure into pipe mounting coupling.
7. Insert the flow element to the insertion depth mark and hand tighten the compression nut. Align the orientation flat parallel to the flow
direction.
8. Tighten the compression nut to the torque specified for the corresponding ferrule material. Compression fitting manufacture recommends
1-1/4 turns past hand tight.
Ferrule Material Torque
Teflon 6 FT-Lbs
316 SST 65 FT-Lbs *
Note:
The metal ferrule configuration can only be tightened one time. Once tightened, the insertion length is no longer adjustable.
Compression Fitting Mounting
1. FCI single point insertion flow meters are calibrated at the centerline of the process pipe. The flow element is properly mounted when
the tip of the flow element is located 0.50 inches (13 mm) past the pipe centerline
2. I = Insertion depth
I.D. = Pipe inside diameter
T = Pipe wall thickness
C = Mounting coupling with and installed compression fitting length
Insertion Depth = I = 0.50 inches + (I.D. / 2) + T + C
3. The scale etched on the side of the insertion pipe indicates the length to the tip of the flow element.
4. Calculate the Insertion depth using the equation in step 2 above.
I = __________
5. Mark the insertion pipe at the calculated insertion depth.
