Product overview
Sigma float operated, target type tank level indicators gauge the liquid level in vertical storage tanks and underground sumps holding water, oil, solvents and similar liquids. They are simple to build and install, very sturdy, and need no maintenance.
A float rides between guide cables whose ends are fastened to an anchor bar, grouted or welded to the tank base, and kept straight by tension devices. The float cable runs over a set of pulleys in the pulley housing. One end of the cable carries the float and the other carries a pointer assembly with a counterweight, so the pointer follows every change in level.
