4532 Mounting
5.3 Mounting on a floating roof tank
There are three methods of mounting the 4532 ATC on a floating roof tank:
Top anchor method
Thermo well method
Guide wire ring method
Note! If the tank bottom has a heating coil, the clearance from the flexible tube or probe
bottom hook to the tank bottom must increase according to the heating coil type.

5.3.1 Top anchor method

The flexible tube is installed in a fixed pipe and stabilized by a top anchor. The 6000
Series Servo Tank Gauge and 4532 ATC can be mounted in the same fixed pipe.

Figure 5-8: Top anchor application

The installation procedure is the same as for mounting on a fixed roof tank using the
top anchor.
