The Acu Gauge is a float type sensing device good from 0”-64” deep tanks

and accurate to 1/10” of an inch.


It has a 3.5 digit backlit display.  The unit runs on either a nine

volt lithium battery, or it can run off of the remote unit’s power source. 

The display has a push button activation with a battery saving

automatic shutoff.


Unit is contained within a weather proof housing. 

 It is semi waterproof (cannot be submerged),

and is good from 30 to 140 degrees Fahrenheit. 

Standard auxiliary output jack with high quality gold plated connections.




The Remote Display  is an optional add on that retains all of the same properties as the Acu Gauge itself. 


 It also offers remote capability, wall cube power, Hi/Lo level adjustable alarms, computer output compatibility, optional set of dry contacts, and plenty of room for customization.




A. Bushing—Machined aluminum 2” bushing fits standard 2” npt tank flange.


B. Housing—Non corrosive machined PVC housing.


C. Cable—Plastic coated stainless steel cable.


D. Misc—Stainless steel screws and connections. 


E. Power—9 volt lithium battery, or it can be run off of the Remote Display power supply.

The ACU Gauge reads in inches and is good up to 64” in total depth.  Its remote display capabilities as well as its vertical motion makes it the most versatile gauge we manufacture.  Without the remote display, it is simply a vertical action digital direct reading gauge.
