All values are theoretical and are calculated making the following assumptions:
1) All bolts are new and material selection is according to EN 1515-1 table 2
2) Gasket material not exceeding 75 shore A durometer is used between the flowmeter and
mating flanges
3) All bolts are galvanized and adequately lubricated
4) The values are calculated for use with carbon steel flanges
5) Flowmeter and mating flanges are correctly aligned
Standard bolts must be well lubricated and
tightened evenly around the gasket. Leakage/
damage to the flowmeter or piping may arise if
bolts are overtightened.
