FITTING SELECTION
Check the part number to determine the required fitting mount size and thread type. EchoSonic
®
is commonly
installed in tank adapters, flanges, brackets or standpipes. Note: Always include the gasket when installing the
EchoSonic
®
.
1.
Tank Adapter:
Select a tank adapter fitting, such as the LM52-1890 for the LU27 series or the LM52-
2890 for the LU23, LU28 & LU29 series.
a. For best results, select a 2” tank adapter and add a reducer bushing such as the LM52-1400,
thread x thread, reducer bushing.
b. Avoid tank adapter (thread x thread) styles and/or pipe stops forward of the installed transducer.
c. Always mount the tank adapter so the majority of fitting is outside the tank.
i. Note:
Never mount the tank adapter upside down or where the bulk of the material is
inside the tank.

Riser:
Installations with tall, narrow risers can impede the acoustic signal.
a.
Core Out Concrete:
Applications where tank with a concrete ceiling that has been cored out
can also be considered as a riser type application. In these applications follow a 2:1 ratio (Core
Height to Inner Diameter) for the diameter of the core.
a.
LU23, LU28 & LU29 Series:
2” (5 cm) diameter risers should be no taller than 4” (10 cm).
Larger diameter risers should be no taller than 12” (30.5 cm).
b.
LU27 Series:

Note:
Do not exceed the dimensions listed above.
Note:
If attempting to raise the
sensor above the top of the tank
to allow for a higher fill capacity,
avoid the use of tall and narrow
risers. The example to the left
exceeds the dimensions listed in
the
Riser Specifications
chart.
Use a larger tank adapter which
takes into account the
Riser
Specifications
