     • Fail-Safe intelligence provides maximum process safety

    The general purpose three-wire ultrasonic transmitter provides non-contact
level measurement up to 40' or 12.2 m with an internal relay that can be
configured as a single-point alarm or latched on two points for automatic
fill or empty control. The transmitter is ideally suited for challenging corrosive,
slurry or waste liquids and is typically selected for large atmospheric bulk storage
and waste sump applications. Media examples include sulfuric acid and resin.

     A high frequency ultrasonic sound wave is pulsed eight times per second
from the base of the transducer. The sound wave reflects against the process
medium below and returns t the transducer. The microprocessor based electronics
measure the time of flight between the sound generation and receipt, and translates
this figure into the distance between the transmitter and process medium below.
