2500 Automatic Tank Gauge
54 Installation and Operations Manual
5. Tighten the adjustment nut until the guide cable is tensioned by the spring. Trim excess
cable.
6. Use pipe thread compound and install top anchor nipples and cap.
Warning Whenever the back cover of the gauge head is removed, stand to one side as
the last bolt is removed. If the negator motor spring is broken, the broken pieces may
cause injury when the cover is removed.
7. Remove the back cover and gasket from the gauge head.
8. Remove the bolts, covers, and gaskets from the elbows.
9. Apply pipe thread compound and attach the gauge head to the exterior vertical pipe. Posi-
tion it for convenient reading. The weight of the gauge head is supported by the pipe and
brackets.
10. Using the box that the tape came in, pull the tape out like a measuring tape. This keeps the
tape from becoming twisted or kinked. At the elbow on the tank entry pipe, unroll one or
two turns of the perforated tape and start to feed it into the horizontal pipe.
Caution If the tape binds in the pipe during threading, check the pipe for corrosion and
other obstructions. Check the tape to make certain that it did not kink. Friction in the pipe
will affect accuracy and may break the tape.
11. Install the gauge tape and 'U' piece to the tape connector with the tape clamps and screws
provided.

12. Attach the tape connector to the float, pass it through the hatch and attach the eyes to the
guide cables.
Caution Do not allow the float to fall back to the floor of the tank! Damage to the float
or tank may result. If necessary, use an assistant to help secure the float so it does not fall.
13. Lower the float until it is hanging from the tape. Inspect the tape and cables for twists and
kinks. Make sure that the cables are parallel, then lower the float to the surface of the
product.
