FITTING SELECTION
Check the part number to determine the required fitting mount size and thread type. LVU700 series is
commonly installed in tank adapters, flanges, brackets or standpipes.
Note: Always include the gasket when
installing the “G” threaded LVU700 series.
1. Tank Adapter: Select a tank adapter fitting, such as the LVU800-2B tank adapter for 2” sensors or the
LVU800-3B for 3” sensors.
a. For best results, select a 3” tank adapter (LVU800-3B) and add a reducer bushing such as the
LVU800-3N40, 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.

2. Riser: Installations with tall, narrow risers can impede the acoustic signal.
a. Core Out Concrete: Applications where a 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 (Inner
Diameter to Core Height) for the diameter of the core.
a. 2” (5 cm) diameter risers should be no taller than 4” (10.0 cm). Larger diameter risers should be
no taller than 12” (30.5 cm).

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
