The Acculevel high accuracy level transmitter incorporates microprocessor-controlled signal conditioning to provide outstanding accuracy over temperature. It provides dual outputs, one analog (current or voltage) and one digital RS485. The RS485 connection allows users to retrieve both level and temperature data, interface with a PC, and rescale the analog output from 10% to 110% of the basic range (converter cable and Keller software required).
Keller level transmitters provide an infinite combination of level ranges, output options, and cable lengths, which ensures the perfect fit for monitoring equipment. They are frequently paired with a SCADA, PLC, or compatible display / control system for use as a water level indicator or controller.
KELLER submersible level transmitters offer high accuracy down to 900 feet with built in lifetime lightning protection and standard three day shipping. Known for their superior reliability, reasonable cost, and ready availability, Keller submersible level transmitters feature small size and integral signal conditioning; simplifying installation anywhere quality liquid level sensors are needed.

This exceptional instrument has been certified to NSF/ANSI 61 and 372 standards for use in drinking water applications. And, on models equipped with 4…20mA analog output, the Acculevel submersible level transmitter also includes guaranteed lightning protection. This internal circuit is included at no additional cost and provides a lifetime warranty against damage from voltage surge.
The Acculevel by KELLER America provides standard features that far exceed those of comparably priced transmitters, including standard ±0.25% FS or optional ±0.1% Total Error Band (TEB) accuracy. This level transmitter is approved to NSF/ANSI 61 and 372 standards for water quality and includes KELLER America’s guaranteed lightning protection, making the Acculevel an outstanding value for liquid level measurement.
The ability of the Acculevel to provide this level of sustained performance over a wide range of operating conditions makes it ideally suited to an equally wide range of applications, including drinking water, stream and reservoir level, environmental monitoring, tank level, wastewater, and for installations in areas prone to chronic damage due to transients caused by lightning.
