The Eliminator™
Rotogauge Replacement
For LP Gas & NH3Service
Application
The Eliminator™direct-reading float gauge is a direct re place ment
for 1" NPT rotary-type gauges in LP and NH3storage tanks.
These gauges are de signed for larger tanks up to 84"
[2134mm] in diameter. The Elim i na tor™is not intended for use
in filling tanks - its use is re strict ed to tanks with fixed liquid level
gauges, used to determine when the maximum fill level has been
reached. The eliminator can be used in mobile ap pli ca tions up to
72" [1828mm] in diameter.
How To Do The Conversion
1. After the storage tank has been evacuated, remove the ro ta ry gauge
from the 1" NPT open ing at the centerline of the head. Clean and re-
tap the fe male threads.
2. Remove the two screws from the bezel. Put the bezel,
screws and dial chamber aside for the moment. Remove the four
mount ing screws holding the gauge head to the adapt er.
3. Insert the lower portion of the replacement gauge, including the float
bulb, float arm, gear hous ing and counterbalance, into the tank open ing.
4. Apply three wraps of 1⁄2" [12mm] wide Te flon tape, or other suitable thread
seal ant, to the 1" NPT threads on the steel adapt er through which
the gauge support pass es.
5. Screw the adapter into the tank open ing to achieve a leak-tight
joint, and align the gauge mounting holes in the hor i zon tal plane.
6. Using the gasket and four mounting screws supplied, attach the
gauge to the adapter fingertight. Be sure the gauge is right side
up, the bracket tab for lo cat ing dial cham ber should be on the
right. Torque the mounting screws even ly to 140/150 lb.in.,
[16,4Nm] us ing a cross pat tern.
7. Reattach the 4" dial chamber and be zel to the Se nior™
gauge head brackets using the two screws supplied.
8. If you end up with the dial cham ber up side down, you cannot
solve the problem by ro tat ing the brack et. You must ro tate the
en tire gauge 180°.

WARNING: Determine and in stall the appropriate replacement gauge based on system re quire ments. The gasket type
supplied may not be suitable for all applications and for those applications other gas ket materials may be available. The in -
for ma tion contained here in is in tend ed for guideline use only and the suitability of any part for a particular ap pli ca tion must
be de ter mined by the user prior to installation. Improper gauge or gas ket selection or application may re sult in seal failure
and sub se quent release of tank contents.
WARNING: Even if gauge registers empty, tank may contain high pressure and flammable gas. Do not remove gauge or other
pressure containing fittings unless precautions against release of tank contents have been taken. A hazard of fire or explosion
may exist if proper methods are not used when removing or installing the gauge or gasket. Replace gasket if gauge is removed.
Do not reuse gasket. When reinstalling gauge head align head for proper orientation of the float inside tank. Torque head or
mounting screws evenly in several steps based on mounting screw size, gasket material & gauge head size & style.
CAUTION: Improper gauge selection or application may result in in ac cu rate gauge readings. Release of tank
contents as well as damage to equipment and safety hazard may result if tank is overfilled. Fuel exhaustion may
occur if tank contents are less than indicated. This gauge is not a substitute for a fixed liquid level gauge or weight
measurement device that may be required for filling.
WARNING: IMPROPER APPLICATION, INSTALLATION, OR USE OF THIS GAUGE MAY CAUSE SERIOUS IN URY OR
PROPERTY DAMAGE.
