It
was a famous female journalist-turned-inventor who gets credit for creating
something so widely used in many industries today. Nellie Bly, along with employee
Henry Wehrhahn received patents in the early 1900’s that led to the modern
55-gallon steel drum. The American Oil and Gas Historical Society recounts how
the invention solved a problem that plagued oil transportation in the early
days; leaking wooden barrels. http://aoghs.org/transportation/nellie-bly-oil-drum/
But
one problem, or at least challenge, has followed the 55 gallon drum since its
invention. You can’t see how much fluid is in there. FNTM 55 Gallon Drum Gauge takes
the guesswork out of it as the first drum gauge that tracks liquid level intervals
in 55 gallon steel drums. FNTM measures oil, transmission fluid, anti-freeze
and other liquids at intervals ranging from 95 percent of capacity down to five
percent.
FNTM: Removing the Guesswork
The battery operated FNTM is in sleep mode until
activated by someone touching either side of the device console. Capacitor
technology then determines and displays the current liquid level inside the
drum for 20 seconds. A siren activates when the fluid level falls below five
percent of capacity. Three LEDs and an additional light at the top of the
console illuminate, as constant indicators that action is required. The FNTM
operates using standard AA batteries.
“The FNTM makes it possible to anticipate when 55
gallon drums will get low on fluid. The interval measurements prompt operators
to take action to make sure they have inventory on hand to serve their
customers,” said Roger Wiersma, BJE Product Engineer.
The FNTM is recommended for automotive repair
facilities and other customers dispensing non-caustic liquids from 55 gallon steel
drums that require more information than high or low level alarms provide.
