I. Company Information Acculevel - The Acculevel from Keller is a high accuracy submersible level transmitter. Keller America Inc is the North American subsidiary of Keller AG für Druckmesstechnik, Incorporating all of the features of the Levelgage including the NSF 61 and NSF 372 which continues as the leader in level and pressure sensing. From humble beginnings, certifications, the Acculevel has additional features that provide enhanced functionality, Keller now provides its products and expertise through a worldwide network of facto- including dual outputs; i.e., one analog (4…20mA, 0…5 VDC, 0…10VDC) and one digital ry-trained professionals. (RS485). The RS485 interface provides level and temperature information and allows the user to rescale the analog output from 10…110% of the basic range. Additionally, the With the advent of inexpensive, miniaturized microprocessors, Keller continues to ad- Acculevel is capable of greater accuracy than the Levelgage, with a standard accuracy of vance the state-of-the-art in fully packaged pressure transmitters, with Total Error Band 0.25% BR TEB and an optional 0.1% BR TEB. The Acculevel can be manufactured in 316L performance not possible just a few short years ago. Annual sensor production now stainless steel or titanium for increased resistance to corrosion, notably from seawater. exceeds 1 million pieces. Acculevel SDI - The Acculevel SDI is a version of the Acculevel high accuracy submersible level transmitter that is available with SDI-12 or RS485 digital communication protocols.
