The Keller Levelgage submersible level transmitter is one of several Keller America models certified by UL to NSF/ANSI 61 and 372 standards for use in drinking water and IS-approved for use in hazardous location applications. The Levelgage can be used in a wide array of applications, including wastewater and water storage and distribution.

The Levelgage is assembled in the U.S to customer specifications, including custom pressure ranges, cable lengths, and a choice of analog outputs (current or voltage). Models equipped with 4 to 20mA analog output include guaranteed lightning protection at no additional cost. This feature protects the Levelgage from fast-rising transients and carries a lifetime guarantee against damage from electrical surge.
