SALIENT FEATURES
DESCRIPTION
TECHNICAL SPECIFICATIONS
Electronet series ULT-200 / ULT-200H are 2 wire Ultrasonic level transmitters designed for non contact type level
measurement. Ultrasonic level measurement is based on the time required by ultrasonic pulses to travel from
sensor to the surface of liquid & back to sensor. Ultrasonic level transmitters are the best for applications such as
slurries, corrosive liquids & waste water. The transmitter provides 4-20 mA DC continuous output with local indication
through LCD. The measuring range is available from 0.6 to 12 mtrs.
