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.

Smart Signal Processing

Overcomes Measurement Difficulties

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 fully-

encapsulated horn antenna offers high performance

and is chemically resistant to nearly all standard

process media. Applications include:
