1 INTRODUCTION
The Penberthy Multiview
™
top mount magnetic
gage (TMMG) is designed for applications
requiring visual indication but with the only access
being a single manway in the top of the vessel.
1.1 Theory of operation
The Multiview
™
TMMG tracks the liquid level
in a process vessel or tank by means of a float
located in the vessel. The float is connected
to a tube. At the opposite end of the tube is
a magnet. The magnet is contained in the
standpipe mounted to the vessel connection.
As the float level changes, so does the position
of the magnet. The level change is visually
conveyed to the operator via the indicator
mounted to the standpipe.
Point level control and remote continuous
level measurement are also available. This is
achieved by attaching electronic switches and/
or a 4-20 mA level transmitter to the exterior of
the communicating chamber.
1.2 System description
The Penberthy Multiview™ TMMG unit consists
of three major sections:
Standpipe chamber
The standard chamber consists of 1" Schedule
10 pipe constructed of 304/304L STS,
316/316L STS, Alloy 20, Monel or Hastelloy-C.
Other chamber materials such as Inconel 625
and Titanium may also be used.
Float
The float is constructed of 316L STS, Titanium,
Alloy-20, Monet, Hastelloy-C or Inconel 625.

Indicator
The indicator consists of a series of magnetically
interlocked flags. The flags are black on one
side and gold colored on the other. As the float
rises the flags rotate 180°, changing from black
to gold. Gold denotes where liquid exists, black
where it does not.
