The Eliminator direct-reading float gauge is a direct replacement for 1″ NPT rotary-type dip-tube gauges in LPG, NH3 and NGL storage tanks. These gauges are designed for larger tanks up to 96″ [2134 mm] in diameter. The Eliminator is not intended for use in filling tanks – its use is restricted to tanks with fixed liquid level gauges, used to determine when the maximum fill level has been reached.
