In the event the transmitter does not receive an
echo, the Select Fail Safety Output setting can be
set either to 22mA, 21mA, 20mA or HOLD the last
value to achieve the desired fail-safe condition.
During fail-safe, the display will read LOST.

Part#: 200129 (2”)
The transmitter allows you to switch the 4-20 mA value at the top and bottom of the
application. By default, 4mA is configured as the bottom and 20mA is configured as
the top. The transmitter displays this as NORM. Follow these instructions to reverse
this setting:
1)
Enter the configuration menu

Set Units
Mounting the Transmitter
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.
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.
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.
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.
Setting Units
Follow these instructions to set how units are displayed:
1)
Mounting with a Tank Adapter: Select a tank adapter fitting, such as the LM522890.
Enter the configuration menu (as
discussed previously),
2)
Select UNITS from the menu,
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".
3)
Select the type of unit or the type of
DISPLAY you desire, and
Mounting with a Side Mount Bracket: Use Flowline's LM50-1001 side mount
bracket.
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:
Riser Mounting
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.

Setting Fill Height
Side Mounting
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.

Mounting with a Standpipe
IMPORTANT MOUNTING GUIDELINES:
1)
2)
3)
4)
5)
6)
Never mount the sensor at an angle.
Liquid should never enter the dead band.
Mount at least 3” from the side wall.
Never mount in a vacuum.
Do not obstruct the sensor’s 3” beam width.
Isolate air gaps between inner and outer threads for best performance.
Some final notes on safety:
Where personal safety or significant property damage can occur due to
a spill, the installation must have a redundant backup safety system.
Wiring should always be completed by a licensed electrician.
Supply voltage should never exceed 28 VDC.
The sensor must be chemically compatible with the application.
Design a fail-safe system for possible sensor and/or power failure.
Never use the sensor in classified hazardous environments.
Configuring the Transmitter
Wiring the Transmitter
The following wiring diagrams can be used when wiring the transmitter.
The transmitter features a non-volatile memory,
and can be configured prior to installation. Your
configuration will not be lost when the transmitter is
powered down.
Before configuring, be sure to have the following
information:
Height. This is the distance from the transducer
face to the bottom of the tank.
Fill Height (Fill-H). This is the distance from the
highest level of liquid to the bottom of the tank

appears. Once you've made your configuration changes,
press SELECT again when “Exit” appears to scroll through
the options and once more while RUN appears in the display.
This will return the transmitter to its operational mode.
