Thank you for purchasing Loop-Powered Meter (LI25). The LI25 Series is a multipurpose, easy to use digital process meter ideal for
level, flow rate, temperature, or pressure transmitter applications. It accepts current and voltage signals (e.g. 4-20 mA, 0-10 V) and has
three front panel buttons that can be programmed for specific operation.
Ordering Information
Installing the Loop-Powered Meter
When unpacking the Loop-Powered Meter, thoroughly inspect the unit for any damage that may have occurred during shipping. Be sure
to report any damage, as well as any missing parts or malfunctions to your supplier or Flowline.
Mounting the Panel
When mounting the panel, first prepare a standard 1/8 DIN panel cutout – 3.622" x 1.772"
(92 mm x 45 mm), as shown in the following diagram.
Allow at least 4.0" (102 mm) clearance behind the panel for wiring.
Be sure to maintain a minimum panel thickness of 0.04" - 0.25" (1.0 mm - 6.4 mm) to
maintain type 4X rating. This would equal 0.06" (1.5 mm) for a steel panel and 0.16"
(4.1 mm) for a plastic panel.
Remove the Loop-Powered Meter’s two mounting brackets. Back-off
the two screws so that there is ¼" (6.4 mm) or less through the bracket.
Slide the bracket toward the front of the case and remove it.
Insert the Loop-Powered Meter into the panel cutout.
Install the mounting brackets and tighten the screws against the panel.
To achieve a proper seal, tighten the mounting bracket screws evenly
until Loop-Powered Meter fits snug against the panel along its short side.
DO NOT OVER TIGHTEN or the rear of the panel may be damaged.

Observe all safety regulations. Electrical wiring should be performed in accordance with all
agency requirements and applicable national, state, and local codes to prevent damage to
the meter and ensure personnel safety.

Signal connections are made via a removal, four-terminal
connector.
This section is intended for the LI25-1001 only. LI25-2001
installation must be performed in accordance with Control
Drawing QS301034-1 in order to meet agency approval.
Signal Connections
Signal connections are made via the four-terminal connector on the LI25
back panel. The loop-powered backlight is an optional configuration and
requires a total maximum voltage drop of 5.7 V. The backlight is
recommended for dim lighting conditions and is enabled when wired as
shown in the following diagram.
The backlight may be bypassed if installed in bright lighting conditions to
reduce the maximum voltage drop to 2.0 V as shown in the following
diagram.
The Loop-Powered Meter Interface
The Loop-Powered Meter is factory calibrated to read in milliamps prior to shipment. You will not need to recalibrate the meter. The
calibration equipment is certified to NIST standards.
Overview
There are no jumpers to set for the meter input selection.
All setup and programming is performed through the front panel interface.
After power and input signal connections have been completed and verified, apply power to the meter.
Front Panel Operation
Display
The display shows the units for the level or volume of the tank. It also
includes the unit of measurement being displayed. A graphical
representation of the percent full is displayed along the bottom of the screen.
Buttons
Down the right side of the Loop-Powered Meter’s front panel are four
buttons. It is through these buttons that you will set up and configure the
Loop-Powered Meter. These buttons are explained as follows:

Menu. Use this button to enter or exit the Loop-Powered Meter’s Programming Mode, view settings, or access advanced features.
Method #1
0% to 100%
Reads to the ones place and is not very accurate
Method #2
0.0% to 100.0%
Reads to the 1/10’s place and provides good
accuracy
Method #3
0.00% to 100.00%
Reads to the 1/100’s place. The accuracy is very
good but may not be practical

Right Arrow/Reset. Use this button to move to the next digit during digit or decimal point programming. This is also used to reset the
max/min readings or other parameter/function assigned through the User menu
Up Arrow/Max. Use this button to scroll through the menus, decimal point, or to change the value of a digit. This is also used to display
max/min readings or other parameter/function assigned through the User menu
ACK. This functions as an ENTER key. Use this button to access a menu or to accept a setting. Programming changes are only saved
after this is pressed.
Programming the Loop-Powered Meter
To enter the Loop-Powered Meter’s Programming menu, press the MENU button. With the UP arrow, you can scroll through three
menu options: Setup, Program, and Password. Each of these options is explained
below.
Setup. This selects: 1. Decimal point position, 2. Units displayed.
Program. This changes Scale options, allows for Calibration and sets the graph.
The display has been calibrated to NIST and will not need to be re-calibrated.
Password. Set or change password access through this option.
QUICK SETUP AND PROGRAMMING
This section will take you through the key steps in setting up and programming the Loop-Powered Meter:
1) Decide on units of measure
2) Select decimal points
3) Set the SCALE function
4) Set the unit in the display
5) Adjust the bar graph
Decide on units of measure
The LI25 series can show level (ex. inches, centimeters, feet, meters, etc) or Volume (gallons, liters, etc.) or any other engineering
units. Please determine the units of operation that you want to appear on the display. This will give you a set point for the environment
you are measuring.
Select decimal points
The decimal point may be set to as many as five decimal places. Use the Decimal Point feature to position the decimal point for all
values displayed. Placement of the Decimal Point can influence the displayed output of your process. For example, setting a scale of 0
to 100% can be show in three different methods:
When selecting a decimal point, take into account the practical scale for reading the level of liquid.

1) Press the MENU button to bring up the Setup screen.
2) Press the ACK button to bring up the decPT screen.
3) Press the ACK button and the decimal point display screen will appear
as “dd.ddd”. This screen allows you to set the decimal point in your display.
Use the Right Arrow/Reset button to move the decimal point on the screen
from left to right. When it is in the position you desire, press the ACK button
to save that choice.
4) Press the MENU button to close the programming menu.
Setting the SCALE function
The Loop-Powered Meter displays information about tank contents in engineering units. Typically, this means that a full tank is
displayed with a value of 4 mA and an empty tank is displayed with a value of 20 mA. You can scale this information to the levels of full
and empty that you wish. A signal source is not needed to scale the meter.
Enter the value you wish the 4 mA signal to reflect and the value you wish the 20 mA signal to reflect. By configuring the transmitter to 4
mA when the tank is empty and 20 mA when the tank is full, this will show the Empty Display setting (Display 1) as 0 units and the Full
Display setting (Display 2) as the full value of the tank.
The Loop-Powered Meter’s default setting is for 2-point linear configuration.. Each point of the 2-point linear configuration has two
settings, the Input and Display. The Input refers to the current and the Display refers to the display value for the current. For example,
with an Input of 20.0 mA and a display of 100.0, the Loop-Powered Meter will show 100.0
when 20.0 mA is supplied to the device.
In the examples above, the 4 mA/Empty reading could represent 0 Gallons, 0 Feet, 0 Inches or 0.0%. The 20 mA/Full reading could
represent 5,000 Gallons, 10.00 Feet, 120.0 Inches or 100.0%. Setting 4mA for an empty tank and 20 mA for a full tank simplifies
configuration.
