RICOCHET BULK TANK
ALPHASONIC LEVEL TRANSMITTER
• Accurate and reliable level measurement from 0.5 (.15) to 12 feet
(3.7 meters)
A high frequency ultrasonic
sound wave is pulsed three 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
receipt, and translates this figure into the
distance between the transmitter and
process medium below.
• Low-cost solution for OEM and
process applications
• Compact size and 2” transducer
for small tanks
• PP enclosure rated NEMA 4X with
PVDF transducer
• Echo-safe™ filtration eliminates
false echo signal returns
• Fail-safe intelligence provides
maximum process safety

APPLICATION
The two-wire, bulk tank alphasonic
level transmitter is mounted through
the top wall of the tank and provides
non-contact measurement up to 12’.
With non-contact technology, the
transmitter is an excellent choice for
applications with dirty, coating, corrosive type liquids. The compact design
is the perfect size for small tank applications.

Relay Control Accessories
For remote relay control and indication, package your level
transmitter with the LC52-1001 continuous relay controller.
The spanable controller features up to three process set
points with two relay outputs and an isolated 4-20 mA
repeater.
Continuous Relay
Controller
LC52-1001
For multi-tank relay control and telemetry, complete your
level package with the LC55-1001 LeveLink controller. The
controller will automate up to eight tanks with 8 transmitter
inputs and eight level switch inputs and eight relay output
channels.
