NOTICE
Gaskets shall not protrude
Ensure the gaskets fit concentrically. Otherwise the flow profile can get distorted.
NOTICE
Devices with hard rubber or soft rubber liner
• Devices with a hard or soft rubber liner always require additional gaskets.
• Siemens recommends using gaskets made from rubber or rubber-like sealing materials.
• Do not scale up the tightening torques to fit your gasket selection. See Torque values
(Page 33).
Procedure
Fasten screws according to the torques values below
Mounting
Torque sequence
1. Remove the liner protectors, if present. Mounting (Page 28).
2. Position the sensor plane parallel and centered between the pipes.
3. Install gaskets between mating surfaces according to recommendations.
4. Consider the torque values and use approproiate bolts.
5. Tighten the bolts crosswise as shown in the torque sequence. Increase the torque gradually:
– Tighten the bolts to 50 % of maximum torque.
– Tighten the bolts to 80 % of maximum torque.
– Tighten the bolts to maximum torque, but do NOT exceed.
