2.9.1 Torques and pressures
The maximum pressure and torques values for the flowmeter are theoretical and calculated for
optimum conditions and use with carbon steel flanges.
• Always tighten the bolts uniformely and in diagonally opposite sequence.
• Do not exceed the maximum torque value.
• Step 1: Apply approx. 50% of max. torque given in table.
• Step 2: Apply approx. 80% of max. torque given in table.
• Step 3: Apply 100% of max. torque given in table.
