12.5.4 Flange Mounting – ST 700 Basic Transmitter
Figure 50 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.
