The 1518M/1519M Mechanical Gauge is designed to be used to measure liquid level in an aboveground storage
tank. The gauge mounts to the top of the tank and is activated by a oat connected to a cable. The 1519M
provides a single level alarm relay output, NO or NC, congurable to the desired level. The alarm relay output
requires an external alarm box, such as the 918 or 918AC series alarm boxes.
Failure to follow any or all of the warnings and instructions in this document could result in a hazardous
liquid spill, which could result in property damage, environmental contamination, re, explosion, serious
injury or death.
NOTE: The most accurate method to calibrate the tank is with uid in it. This will take into account variables
associated with the oat position, the mechanism, and the uid density.
Installation
WARNINGS
• Fire Hazard – Death or serious injury could result from spilled liquids.
• Any modication to this gauge other than those stated in these installation instructions will void the product
warranty.
• This device is intended to be used as a liquid level indicator to the operator and should not be the only system
in place to prevent a tank from overlling. It is the sole responsibility of the operator to continuously prevent
any spillage regardless of the situation or status of the gauge.
• Install in accordance with all applicable local, state and federal laws.
• For your safety, it is important to follow local, state, federal and/or OSHA rules that apply to working inside,
above, or around the storage tank and piping area. Use all personal protective equipment required for
working in the specic environment.
• Tanks could be under pressure. Vapors could be expelled from tank vents, piping, valves or ttings while
performing installation. Vapors could catch re or cause an explosion. Avoid sparks, open ame, or hot tools
when working on gauge.
• Use a dampened cloth when cleaning the clear front cover of the gauge to prevent static buildup and
discharge.
• In the event of malfunction, contact Morrison Bros. Customer Service.
Steps
1. Verify contents of box. You should have received the gauge, oat, and a small tube of adhesive (See Figure
1). Inspect the items for shipping damage. DO NOT use if damage is found.
2. Remove the front cover of gauge and remove foam under cover. NOTE: The Philips screws in the front
cover are captive fasteners that aren’t meant to be removed. Place the front
cover back on gauge. Place the front cover back on gauge. The gauge
should be reading approximately 111 centimeters. If not, the gauge could
be damages or dysfunctional. Inspect the internals for any damage. DO
NOT use if damage is found. Find the cable sticking out of the end of the
gauge connection pipe. Slowly pull on cable to ensure gauge is functioning
properly. DO NOT pull and release cable uncontrollably. This can cause
damage to the internal mechanism and render the gauge inoperable.
ALWAYS hold onto cable and allow it to move in
a slow steady motion.
3. Remove the red warning tag
4. If installing a 1519M gauge, refer to page 3 for calibrating alarm set point.
5. Locate the opening on the top of the tank where the gauge is to be installed (minimum opening size is 2”
schedule 40 pipe). If possible, select a location away from the ll port to avoid excessive turbulence that
could aect the oat. Also make certain that there are no objects inside the tank, near the selected opening,
upon which the oat and cable could get tangled and that the gauge location will not interfere with normal
operation of the tank.

6. NOTE: Once an opening is selected, use a tank stick or
gauging tape to determine the current liquid level height in the
tank. Record this liquid level as you need it to set the gauge
once it is installed.
7. Carefully lay the gauge on the top of the tank, near your
selected tank opening.
8. Attach the necessary pipe bushing to adapt the 1” gauge
connection pipe to the connection on the tank opening. Apply
PTFE tape to the male threads on the gauge connection
pipe and thread into your pipe bushing. DO NOT use any
pipe dope as this may get on the gauge cable and cause a
malfunction.
9. Next you need to attach the oat to the cable screw on the
end of the gauge cable. Unscrew the cable bullet exposing the cable screw threads. The cable bullet is now
no longer needed and can be discarded. Using the small tube of adhesive provided, place a drop or two of
the adhesive onto the male threads, of the cable screw. Thread the oat onto the cable screw and, while using
pliers to carefully hold the oat connector, snug the oat onto the cable screw (See Figure 2). NOTE: Make
sure to do not damage the cable with the pliers.
10. SLOWLY lower the oat into the tank. Guide the cable through your ngers letting the cable slide through
slowly. DO NOT allow the oat to free fall into the tank as this will cause the cable to come o of the pulley
mechanism and render the gauge inoperable. NOTE: make certain that when lowering the oat, that the
cable DOES NOT rub on the edge of the tank opening.
11. Once the oat is resting on the liquid level (or tank bottom if the tank is empty) apply PTFE tape to the pipe
bushing on the bottom of the gauge connection pipe. DO NOT use pipe dope as this may get on the gauge
cable and cause a malfunction.
12. Lift the gauge to the vertical position and thread the pipe bushing into your tank opening. Make certain
that you do not allow any excess slack in the cable or kink the cable in any way. Once you have threaded
the gauge into the tank opening hand tight, use a pipe wrench or strap wrench, on the 1” gauge connection
pipe, to complete tightening. Torque threads to 75-85 ft-lbs.
13. Now the gauge can be calibrated to the liquid level you found in step 4. Calibration is done one indicator
wheel at a time (See Figure 3). Start with the ones’ centimeter indicator wheel. Grab the indicator wheel and
push it to the left to clear the drive gear. The ones’ centimeter indicator wheel must be fully disengaged from
the drive gear. The indicator wheel should now freely spin. Spin the wheel UPWARDS so that the numbers
are counting up. Once at the correct
setting, slowly let indicator wheel seat
back into the drive gear. Failure to
follow this procedure can cause damage
to the internal mechanism and render the
gauge inoperable. Note: desired level
reading needs to be in the center of
the viewing window.
14. Calibration for the tens’ and hundreds’
centimeter readings is done in a similar
manner pushing the indicator wheels to
the left so they clear the gears that are
oset below the indicator wheels (See
Figure 3.) Calibrate the tens’ centimeter
indicator wheel and then the hundreds’
centimeter indicator wheel. Note:
desired level readings need to be in
the center of the viewing window.
15. Reinstall the front cover, the correct
settings should be clearly centered in
viewing windows. If needed, adjust the
indicator wheels.
16. The tank manufacturer’s chart will be
required to translate uid height into uid volume.

Failure to follow any or all of the warnings and instructions in this document could result in a hazardous
liquid spill, which could result in property damage, environmental contamination, re, explosion, serious
injury or death.
1519M Calibrating the Alarm Set Point
1. Each gauge’s alarm set point will be factory defaulted to
at 111cm.
2. The alarm set point uses a magnet that is attached to the
indicator wheel using a magnet positioner. The alarm set
points are activated when the magnet is above the circuit
board that is located behind the indicator wheels.
3. There are two magnet positioners. The hundreds’ and
tens’ magnet positioner has two unique ends, see Figure
8. The rst end is the target end that will point to the desired set
point level, and the second end has a pocket for the magnet to set
into. The ones’ cm magnet positioner has three magnet pockets
along with one target arrow, see Figure 9.
4. Start with the ones’ cm indicator wheel rst. While holding the
indicator wheel, remove the magnet screw along with the magnet
and place aside.
5. Push the ones’ cm indicator wheel to the left so that it disengages
the drive gear and rotate the wheel upwards until you reach the
next magnet see Figure 10. Now let the indicator wheel seat back
into the drive gear. While holding the indicator wheel, remove the
magnet along with the screw and set these items aside.
6. Push the ones’ cm indicator wheel to the left so that it disengages
the drive gear and rotate the wheel upwards until you reach the
last magnet see Figure 10. Now let the indicator wheel seat back
into the drive gear. While holding the indicator wheel, remove the
magnet, screw and positioner and set these items aside.
7. Now push the indicator wheel to the left again to disengage from
the drive gear. Rotate the indicator wheel upwards to the desired
set point and allow the indicator wheel to seat into the drive gear.
8. Place the magnet positioner onto the indicator wheel with the target
arrow aligned with the desired alarm set point, as shown in Figure
11. While holding the indicator wheel, thread the screw through the
target end hole and into the matching hole in the indicator wheel. DO NOT OVER TIGHTEN, only snug up
the screw.

9. Push the indicator wheel to the left again, disengaging the wheel from the drive gear. Rotate the wheel
upwards to the other magnet pockets. Place a screw through the magnet into the positioner and while
holding the indicator wheel, thread into the indicator wheel. DO NOT OVER TIGHTEN, only snug up the
screw.
10. Push the Ten’s indicator wheel to the left so that it disengages the drive gear and rotate the wheel upwards
until you reach the magnet see Figure 10. Now let the indicator wheel seat back into the drive gear. While
holding the indicator wheel, remove the magnet, screw and positioner and set these items aside.
11. Now push the indicator wheel to the left again to disengage from the drive gear. Rotate the indicator wheel
upwards to the desired set point and allow the indicator wheel to seat into the drive gear.
12. Place the magnet positioner onto the indicator wheel with the target end aligned with the desired alarm set
point, as shown in Figure 12. While holding the indicator wheel, thread the screw through the target end
hole and into the matching hole in the indicator wheel. DO NOT OVER TIGHTEN, only snug up the
screw.
13. Push the indicator wheel to the left again, disengaging the wheel from the drive gear. Rotate the wheel
upwards to the magnet end. Place a screw through the magnet into the positioner and while holding the
indicator wheel, thread into the indicator wheel. DO NOT OVER TIGHTEN, only snug up the screw.
14. These steps are repeated for the hundreds’ cm wheel, see Figure 10.
15. Magnet positioners must be evenly placed on the wheels as in Figure 9 and Figure 10.
16. Setting of the alarm point is now complete, return to page 2 and proceed with step 5 of Installation.
1519M Mounting the Power Module
IMPORTANT: The maximum wiring distance between the Gauge
Head and the Power Module is 200 feet. Do not exceed this distance.
We recommend that the Power Module be mounted in close proximity to
the associated Tank Alarm for the convenience of the operator to verify
the operation of both before performing a ll operation.
NOTE: The Power Module MUST be mounted with the conduit
opening on the bottom to prevent water ingress.
NOTE: The enclosure appears to be square, but it is not symmetrical
in how the cover mounts to the base. Do NOT turn the enclosure 90
degrees and attempt to install the cover; it will not seal properly.
Mount the Power Module on a suitable surface with the wiring opening
on the bottom using the holes provided in the mounting anges of the
enclosure.
1519M Wiring the Gauge Head
IMPORTANT: Do NOT wire the Gauge Head to the Power
module with the battery connected to the Power Module Board.
1. Loosen the four corner screw holding the front cover of the Power
Module in place.
NOTE: These are captive screws and are not intended to be removed.
2. Separate the Power Module’s front cover from the base.
3. Verify that the battery is NOT connected to the Power Module
Board. If it is connected, disconnect it before proceeding.
4. Install conduit between the Gauge Head and the Power Module.
5. Pull the recommended cable between the Gauge Head and the
Power Module not to exceed 200 wiring feet.

8. Run wires between the Dry Contact output of the Gauge Head and the associated Tank Alarm (see Table 1).
Choose the contact type as is appropriate for the Tank Alarm to be used.
NOTE: There are eight (8) wires available in the junction box attached to the bottom of the gauge head.
Five (5) of these are wired to the Power Module.
Three (3) are the dry contact outputs that may be wired to your alarm system. One is Common, one is
Normally Closed contacts and the other is Normally Open contacts. These are a bit longer than the ones
that are wired to the Power Module.
1519M Initial Setup of Power Module
IMPORTANT: In order to accomplish the initial setup of the gauge head, the oat level must be below the
indicated set point.
EXAMPLE: If the alarm level was set at 11 feet 1 inch, then the oat level must be below the 11 foot mark
prior to completing this step.
1. Ensure the oat level is below the set alarm level.
2. Loosen the four corner screw holding the front cover of the Power Module in place.
NOTE: These are captive screws and are not intended to be removed.
3. Separate the Power Module’s front cover from the base.

4. Connect the Battery Cable to the Power Module Board’s J4 connector in the upper right hand corner of
the board. The front panel LED should ash momentarily if the system is alive. If this does not happen,
disconnect the battery and check all wiring connections in the system before proceeding.
5. Press and hold the Test button for more than three (3) seconds. The Low Battery indicator on the front panel
should ash momentarily and then extinguish. If this does not happen, disconnect the battery and check all
wiring connections in the system before proceeding.
6. Locate the small pushbutton, SW1. Right next to the pushbutton is a small, green LED.
7. Press and hold the pushbutton until the LED ashes twice.
8. Release the pushbutton.
9. Replace the front cover back on the base being careful to establish the right registration of cover to base.
10. Secure the cover in place with the four corner screws.

PIPE PLUG
1519M Verify Installation
For a 1519M, gauge the system must be tested before installation is completed.
1. Remove the pipe plug and grab onto the cable (See Figure 20.)
2. To test a high-level alarm, slowly begin pulling downwards on the cable causing the oat to rise in the tank,
this whole time the gauge should be taking up the slack in the cable. To test a low-level alarm begin pulling
the cable upwards causing the cable to fall into the tank.
3. Observe the reading on the gauge, if the alarm device alarms at the desired set point the test is completed;
now slowly allow the oat to drop and the cable back into the gauge. If the alarm device does not alarm,
recheck the wiring, the calibration, and the alarm set point.
Operation
IMPORTANT: Prior to each use, it is imperative that the operation of BOTH the Gauge Head and the Tank
Alarm be veried.
1519M Test the Operation of the Gauge Head
To verify the operation of the Gauge Head electronics and health of the battery, press and hold the “Test” button
on the Power Module for at least 3 seconds.
If all is well, the “Battery Low” indicator will ash
momentarily.
If the “Battery Low” indicator either does not ash at
all or remains illuminated, then do not use the system
or ll the tank until this is corrected. After this is
corrected, the electronics must be reinitialized as
described above in the “Initial Setup” section.
1519M Test the Operation of the
Associated Tank Alarm
In addition to checking the operation of the gauge
head, the attached alarm system would also have to
be veried as functional. Follow the manufacturer’s
instructions for verication of the attached alarm
system prior to any ll operation.
If the Tank Alarm does not respond appropriately per its manufacturer’s instructions, do not use the system or
ll the tank until this is corrected.

Maintenance
WARNINGS
• Fire Hazard – Death or serious injury could result from spilled liquids.
• You must be trained to maintain this gauge. Stop now if you have not been trained.
• For your safety, it is important to follow local, state, federal and/or OSHA rules that apply to working inside,
above, or around the storage tank and piping area. Use all personal protective equipment required for working
in the specic environment.
• Tanks could be under pressure. Vapors could be expelled from tank vents, piping, valves or ttings while
performing maintenance. Vapors could catch re or cause an explosion. Avoid sparks, open ame, or hot tools
when working on gauge.
• Use a dampened cloth when cleaning the clear front cover to prevent static buildup and discharge.
• In the event of malfunction, contact Morrison Bros. Customer Service.
This gauge should be maintained per applicable codes or at least once each year.
Steps
1. Visually inspect the gauge for damage or excessive wear. If either is found replace the gauge.
2. If necessary, clean the clear front lens with a damp cloth.
3. Measure the uid height and verify the gauge reading. If readings do not match adjust the gauge setting
according to the installation instructions.
4. Remove pipe plug at base/tank bracket to drain any condensation.
Check the Enclosure for water ingress no less than once per year.
Addtional steps for the 1519M
1. Carefully open the Power Module enclosure cover by loosening the Phillips head fasteners at the four corners
of the cover.
2. Inspect the interior of enclosure to determine if any water has inltrated the enclosure. If water has inltrated
the enclosure, take corrective action to seal the points of ingress.
3. Inspect the electronics for corrosion. If there is corrosion present on the electronic assembly(ies)
Take corrective action to seal the enclosure from further water ingress.
Contact Morrison Bros. Co. for further action.
4. Reattach the front cover of the Alarm using the Phillips head fasteners at the four corners of the cover. DO
NOT OVERTIGHTEN. “Snug” the fasteners in place and verify that the cover is fully seated to the enclosure
base.
