Never come up empty—reads to ±0.50 gallon (1 liter).

• Resists temperature fluctuations
• Ideal for applications involving diesel fuel, oils, hydraulic fluid, and water†
• Works with 15, 30, or 55 gallon (57, 114, or 208 liter) vertical drums
• Digital display indicates volume in gallons or liters numerically and as an analog bar graph

Ultrasonic drum level gauges feature all laser-welded design and custom integrated signal conditioning for calibration and temperature compensation.

Connects directly to the 3/4" and 2" bungholes of a drum. Digital display indicates volume in gallons or liters numerically and as an analog bar graph. A red, low-level warning light also illuminates when total volume drops below 10%.
Can operate on two 9 V batteries (not included) to display a static reading; update the level readings by pushing the "Refresh/Select" button. Model 68349-53 can also be powered by 24 VDC to obtain continuously updated level measurements and to take advantage of the 4 to 20 mA output. Auto shut-off feature prolongs battery life.
