The Levelgage by Keller America is designed for indefinite submersion in a wide variety of liquid media. It provides a temperature-compensated analog output proportional to the height of the liquid column above the transmitter. Intended for general purpose monitoring and control applications, the Levelgage is a smart choice for OEMs, system integrators and end users alike. Keller America’s guaranteed lightning protection makes this transmitter ideal for installation in areas prone to chronic damage due to transients caused by lightning.
