Signal Returns

A high frequency sound wave is
pulsed two 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
measure the time of flight between
the sound generation and the
receipt, and translates this figure
into the distance between the
transmitter and the process
medium below.

The two-wire, small tank non­contact level transmitter is mounted
through the top wall of the tank and
provides non-contact measurement
up to 1.8 m (6'). With non-contact
technology, the transmitter is an
excellent choice for applications
with dirty, coating or scaling type
media such as acid waste. The
compact design is the perfect size
for small tank applications.
