SAMPI LC Sound - Manual

The LC Sound is an ultrasonic air sensor, available
with 2”, 3”, 4” square flange. It continuously
monitors the presence of air/gas in a delivery, and
upon detection of gas the output relay is opened.
The typical application uses the output contact to
control valve, pump or can be connected to a
smart device. The technology guarantees accurate
deliveries with no pressure drop, both in terminal
and truck installations. The sensor uses an
ultrasonic transceiver to transmit a high frequency
pulse: the signal reaches the reflector placed on
the other side of the flange and then comes back
to the transceiver. The signal amplitude level is
proportional to the presence of liquid: if air is
detected, the output relay is opened.
