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. ? chemical storage tanks ? vessels with highly viscous media ? paint, ink and solvent tanks ? food and beverage vessels ? batch and day tanks ? open channel flow weirs and flumes 355 ultrasonic transmitter 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: ? liquids, slurries and viscous media ? general chemical storage ? day, batch and feed tanks ? food and beverage vessels ? water/wastewater tanks and sumps R82 radar transmitter agitator blade shaft fill pipe turbulent process ladder and fill pipe obstacles visible vapors aerated process; in-tank air movement
