5.12 Mounting NMT81 on a floating roof tank
There are three ways to mount NMT81 on to a floating roof tank.
• Top anchor method
• Stilling well method
• Guide ring and anchor weight method
If a heating coil is attached to the bottom of the tank, install NMT81 so that the bottom
hook of a temperature probe or a WB probe is not too close to the heating coil.
5.12.1 Top anchor method
Insert a temperature probe or a WB probe into a fixed pipe and secure it with a top anchor.
To prevent damage to temperature probe and WB probe, ensure that they do not touch
anything during insertion through the installation nozzle.
