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.

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:
