5. Stand Pipe: A standpipe maybe used to dampen turbulence or when foam is present in the
application.
a. Pipe can be made of any material.
b. Select a minimum 3" ID pipe for the stand pipe.
i. A 2" pipe is usable with the LVU809 series, but is the minimum.
ii. Pipes larger than 3" can also be used.
c. Use a coupling and reducer bushing to attach the LVU800 Series to the pipe.
i. With the LVU809 series, be sure to use a plastic reducing bushing such as the 2" Thread
ii. With the LVU816, LVU826 or LVU832 series, be sure to use a plastic reducing bushing
d. The pipe length should run the measurement span and the bottom of the pipe should remain
submerged at all times to prevent foam from entering the pipe.
e. Cut a 45°notch at the bottom of the pipe and drill a 1/4"pressure equalization hole in the dead
band.
f. The pumps should not drive liquid past the open end of the stand pipe which causes the liquid
in the pipe to oscillate.
