Set Units
The transmitter displays information in inches,
feet, centimeters, meters, or percentages. This
can be displayed to represent the amount of air
or the amount of liquid in a tank.
Air Display Mode shows the distance from the
bottom of the sensor to the liquid surface. Liquid
Display mode show the distance from the liquid
surface to the bottom of the tank.
Follow these instructions to set how units are displayed:
1) Enter the configuration menu (as
discussed previously),
2) Select UNITS from the menu,
3) Select the type of unit or the type of
DISPLAY you desire, and
4) Select EXIT to return to the Configuration
menu.
Set Height and Fill Height
This setting customizes the reading for your installation. Follow these instructions to
set the height and fill height for your tank:
1) Enter the configuration menu (as discussed previously),
2) Select TANK from the menu,
3) Select HEIGHT. Use the UP and DOWN buttons to set the height of your tank. Then,
hold down the SELECT button to save this setting,
4) Select FILL-H for the fill
height. Use the UP and
DOWN buttons to set the fill
height of your tank. Then, hold
down the SELECT button to
save this setting, and
5) Select EXIT to return to the
Configuration menu.
Mounting the Transmitter
The transmitter should always be mounted perpendicular to the liquid surface using the
provided Viton® mounting gasket. Insure that there are no restrictions or obstacles in the
path of the ultrasonic signal.. Further mounting information can be found on the Flowline
website at www.flowline.com.
The LU81, 83, & 84 has a 2” NPT or G fitting that can be installed in standard 2” tank
adapters. It is best to keep the height of any adapter to a minimum with 6” being the
absolute maximum for a 2” riser. The LM-1001 is a good choice for sidewall mount
applications.
Mounting with a Tank Adapter: Select a tank adapter fitting, such as the LM52-
2890.
Mounting with a Riser: As installations with tall, narrow risers can impede the
acoustic signal. 2" diameter risers should be no taller than 5". Larger diameter risers
should be no taller than 12".
Mounting with a Side Mount Bracket: Use Flowline's LM50-1001 side mount
bracket.
Mounting with a Stand Pipe: A standpipe may be used
to
dampen turbulence, separate surface foam from the point
of measurement or increase performance in heavy vapor.
Select a 2” pipe and attach the transmitter with a coupling
and reducer bushing. 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. Cut the bottom end of the pipe at 45°
and drill a 1/4”pressure equalization hole high in the dead
band. The pumps should not drive liquid past
the open end of the standpipe which causes the liquid in
the pipe to oscillate.
