Riser:
Installations with tall, narrow risers can impede the acoustic signal. Select a
fitting with the right riser height versus inner diameter geometry.
3.
Flange:
If installing on a flange, select a flange with a thread that is above the plane of
the flange, such as the Spears 2” One Piece Flange (series 852-020). 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 2" Poly ANSI Flange (series AF200).

Do not use thread in plane
If the installation requires the use of a blind flange, tap a thread 1” larger than the sensors
thread and add a Reducer Bushing such as a Spears thread x thread Reducer Bushing [Use
the 839-338 (3” x 2”) for LU78 series or 839-249 (2” x 1”) for LU77 series].
4.
Side Mount Bracket:
The LM50-1001 side mount bracket or equivalent can be used for
open tank top installations against the sidewall. For the LU77 series, order the LM50-
1001-1, which includes a 2”x 1” Reducer Bushing.
