Customer specific designs for the measuring flange can be supplied by AMO (Type WMF) or the measuring flange will be supplied by the customer for mounting the measuring ring at AMO (Type WMB). In this case the diameter for mounting the measuring ring can be calculated as shown in the table on the next page.
The accuracies shown below can be increased by a factor of 4 using MHS or CHS as a measuring system (see page 57).
The production drawing for the carrier flange can be released by AMO.
For applications with large diameters or significant variations in temperature during operation the system must be designed accordingly.
