Carefully follow the instructions given in the diagrams. Check the correct centering of the sensor before you
tighten the flanges and proceed following the steps described here.
Step 1. ≈ 50% of the maximum tightening torque
Step 2. ≈ 80% of the maximum tightening torque
Step 3. 100% of the maximum tightening torque given in the diagram
All the values are theoretical and have been calculated for optimal conditions and with the use of carbon steel
flanges.
