The Eliminator

Rotogauge Replacement
For LP Gas & NH

Service
Application
The Eliminator
™
direct-reading float gauge is a direct re place ment
for 1" NPT rotary-type gauges in LP and NH
3
storage 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°.
