Operating Principle
Measurement is obtained by
emitting an ultrasonic pulse from
the transducer and measuring
the time required for the echo to
reflect from the liquid surface
and return to the transducer.
Smart Signal Processing
Overcomes Measurement Difficulties
355
Ultrasonic Transmitter
The intelligent electronics of the Model 355 Transmitter
analyze the ultrasonic echo profile, apply temperature
compensation, reject echoes from false targets,
and then processes the true echo from the
liquid surface. This results in an extremely
reliable measurement even when application
difficulties exist like turbulence or false
echoes generated by agitator blades, fill
pipes or other internal tank fittings.
The 60 kHz ultrasonic transducer is offered in
polypropylene or Kynar for superior performance
in harsh environments. These powerful transducers
feature a 10° conical beam and 10" (255 mm) blocking
distance to maximize measurement capabilities in a
wide variety of applications.

R82
Radar Transmitter
The sophisticated circuitry of the R82 transmits, receives
and processes 1.8 million pulses per second to
ensure reliable measurement. The R82 measures
effectively even when atmospheres above the
liquid are saturated with vapor. Pulse Burst
technology and advanced signal processing
manage common disturbances such as false
echoes caused by obstructions, multi-path
reflections from tank sidewalls or turbulence
caused by agitators, aggressive chemicals,
or aerators.
The R82 launcher orientation and echo-rejection
profiling are simplified for easy use. The microwave
beam is rotatable for optimized operation. The fullyencapsulated horn antenna offers high performance
and is chemically resistant to nearly all standard
process media. Applications include:
