Microlevel - Microbore Submersible Level Transmitter
The Microlevel combines the high accuracy of the Acculevel with a class-leading housing diameter of only 0.63". It incorporates KELLER's proven microprocessor-controlled signal conditioning to provide outstanding accuracy over temperature. It provides dual outputs, one 4-20mA analog 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).
The Microlevel is assembled in the U.S. to customer specifications, including custom pressure ranges and cable lengths, and includes KELLER's guaranteed lightning protection. This protection is included at no additional cost and carries a lifetime guarantee against damage from electrical surge.
The Microlevel is now available in titanium for use in more aggressive media applications not suited for stainless steel.
