HOW IT WORKS
When the trigger is depressed, high intensity bursts of focused infrared light are transmitted by a solid state LED  (Light Emitting Diode) across a probe gap, which contains either liquid or sludge. The highly penetrating infrared beam is received by a sensitive phototransistor on the other side of the gap. This pulsing is repeated many times per second by the electronic control circuit. If the gap contains air or clear liquid, nothing happens. However, when suspended solids are encountered in the gap, some beam energy is absorbed, and the rear-facing loudspeaker on the butt of the gun starts to howl. As the percent solids content increases, both the pitch and volume of the sound increase which gives the operator a clear indication of where the thickest sludge is located. By holding the trigger and listening to the note while slowly moving the probe up and down, the operator can observe the depth markers on the cable and establish the location of both the sludge blanket and the overlying unsettled layer.

EASY TO USE
Markland's popular Sludge Gun® makes even an inexperienced operator an expert at sludge level detection. A trigger turns on the gun, and a thumb adjustable sensitivity control compensates for thin or thick sludges. There can be no mistaking the loud howl of the speaker as the probe enters the sludge bed. Variable pitch sound (higher pitch for higher % solids) permits locating both the upper and lower limits of the settling zone above the sludge bed. After use, the cable is wound on the self-storing spool at the front of the gun. The one hand, one piece, Sludge Gun® detector is easy for an operator to carry from tank to tank. Use it in the rain or snow, day or night. This rugged tool is a valuable addition to any plant.
