Installation
Step Seven
Flange (LU27 series):
If installing on a flange, select a flange with a thread that is above the plane of the
flange, such as the LM52-1850.
a. The LU23, LU28 & LU29 series works well with Flange installations.
b. Avoid the use of blind flanges with tapped threads or flanges where the threads are even with
the plane of the flange, such as the Banjo 1" Poly ANSI Flange (series AF100).
c. Use a flange with a 2” thread and add a 2” to 1” reducer bushing to complete the installation for
the LU27 series.

Side Mount Bracket:
For installations in open tanks and sumps, use the LM50 series side mount
bracket.
a. For the LU27 series, order the LM50-1001-1, which includes a 2”x 1” Reducer Bushing.
b. For the LU23, LU28 & LU29, series, order the LM50-1001 side mount bracket.

Note:
The Side Mount Bracket (LM50 series) is not designed for use with stand pipes or as a method
to secure stand pipes. There are too few threads to properly hold the sensor and the stand pipe.
