Set Units
The sensor displays information in inches, feet,
centimeters, meters, or percentages.
This can 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
shows 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) Press SELECT when Tank appears,
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.
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 4". 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 3” or 4” pipe and attach the sensor 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.
IMPORTANT MOUNTING GUIDELINES:
1) Never mount the transmitter at an angle.
2) Liquid should never enter the dead band.
3) Mount at least 3” from the side wall.
4) Never mount in a vacuum.
5) Do not obstruct the transmitter’s beam width.
