2.5.2 Installing devices in flange design
• Use bolts and fastening nuts 2 to attach the measuring device to one side of the flange.
• While doing so, insert the gaskets 1 between measuring sensor and flange and align them.
• Check that the gasket is concentric and that it is not protruding into the pipe cross-section.
• Install the gasket, bolts and fastening nuts on the other side of the flange.
• Align the measuring device and the gaskets so they are concentric.
• Now tighten all nuts bit by bit alternately across the diagonal.
