The Keller Acculevel submersible level transmitter incorporates microprocessor-controlled signal conditioning to provide outstanding accuracy over temperature. The ability of the Acculevel to provide sustained performance over a wide range of operating conditions makes it ideally suited to environmental monitoring applications such as surface water, streams, and reservoirs. 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).

The most recent model is the serial digital interface version, the Acculevel SDI. It combines two industry standard digital communication protocols (SDI-12 & RS485) and is suited for environmental monitoring applications using existing SDI-12 monitoring equipment. The Acculevel SDI is great for remote applications that require battery-powered operation with minimal current draw and networking multiple sensors to a data recorder.

The Acculevel transmitter with PE jacket is approved to NSF 61 and NSF 372 standards for water quality. Models equipped with 4-20mA or SDI-12 output include guaranteed lightning protection at no additional cost. This internal circuit provides a lifetime warranty against damage from voltage surge, making it perfect for installation in areas prone to chronic damage due to transients caused by lightning.

Here's how some of our customers use this product...

Temperature Compensated Well Water Level Monitoring

The Background: Our customer is a farmer who uses a fresh-water well to provide water for all uses on the farm. He requires an accurate means of monitoring water level in this well.

The Problem: The customer has been using a level sensor that was not temperature-corrected which was causing accuracy issues making it impossible to know the true water level in the well.

The Solution: We recommended the Keller Acculevel submersible level transmitter which is fully compensated for temperatures from -10 to 80ºC. The total error band is just 0.1% making it easy for the customer to get accurate results. The Acculevel also offers guaranteed lightening protection making it a great solution for this application.
