3.4.5 Flange Mounting
Figure 9 shows a typical tank-flange mount installation, with the Transmitter flange mounted to the
pipe on the wall of the tank.
On insulated tanks, remove enough insulaiton to accommodate the flange extension.
When flange-mounting to a tank, note the following:
The End User is responsible for providing a flange gasket and mounting hardware suitable for
the Transmitter service conditions.
To avoid degrading performance in flush-mounted flanged Transmitters, exercise care to
ensure that the internal diameter of the flange gasket does not obstruct the sensing diaphragm.
To prevent performance degradation in extended-mount flanged Transmitters, ensure that
sufficient clearance exists in front of the sensing diaphragm body.
