• A stilling well is required in a floating roof tank and a covered floating roof tank.
• Guide wires cannot be installed in a floating roof tank. When the measuring wire is exposed to free
space, it may break due to an external shock.
• Installing guide wires is not allowed in pressurized tanks because the wires would prevent closing
the valve for replacing the wire, wire drum, or displacer. NMS5 installation position is important for
applications without the guide wire system in order to prevent the measuring wire from being bro-
ken (refer to Alignment of NMS5 for details).
