5.5 One Point Level Control for Low Level Shut-Off for Drums, Totes, or Day Tanks
One point level control can be used with drums, totes, or day tanks for low level
shutoff of mixers or pumps. The bottom of the probe should be located 1” up from
the bottom of the container. The level control adjustment screw should be turned
full counterclockwise.
Use tubing in place of the immersion air probe when inserting into drums due to
the small drum openings. The tubing needs to be securely fastened to the foot
valve assembly for the chemical feed pump prior to insertion.
