LU1_-50_1

Application

The general purpose two-wire ultrasonic transmitter provides non-contact level measurement up to 40' or 12.2m, and is ideally suited for challenging corrosive, coating or waste liquids. The transmitter is broadly selected for atmospheric bulk storage, day tank, process vessel and waste sump applications. Media examples include ink and polymer. See the LU12-14 sensor application matrix for more details.
