About Ultrasonic Technology:
An ultrasonic sound wave is pulsed five times per second from the
base of the transducer. The sound wave reflects against the process
medium below and returns to the transducer. The microprocessor
based electronics measures the time of flight between the sound gen-
eration and receipt, and translates this figure into the distance between
the transmitter and process medium below.
