The document describes the specifications, functionalities, and operational principles of the ultra compact and remote ultrasonic level instruments in the UC series. These devices utilize ultrasonic impulses for level measurement and feature advanced technologies like 'echo discovery' and temperature compensation for accurate performance in challenging environments. It provides detailed technical data for various models (UC551, UC552, UC553) including application suitability, measurement range, materials, and communication options.

ULTRASONIC LEVELINSTRUMENTS
(Compact/Remote version)
DESCRIPTION
The ultrasonic impulses generatedfromtransducers“antennasystem”,which travel
at the speed of sound, come reflected by the surface of medium and newly sent
back to thetransducer.
Theperiod of time that passes betweentheemission of impulses and thereception
of the same ones fromthe antenna,is proportionalto the existingdistancebetween
the same antenna and the higher level of the medium to measure, therefore the
principleof the ultrasonic measure can be illustratedwith the following equation:
S=CXT/2,where S: distance,C: velocity of sound,T: timelapse
Because of the wideband impulses, the overlap between the emission and the reception of the same
impulses increasesin particular zones,extending itself fromthe transducerto the bottom,causing a wrong
measurementof the level. This error zone is defined “blanking zones”and its dimensionvarybased on the
various models of ultrasonic metersthatare used.
The use of an advanced microprocessorand the technology “EchoDiscovery”, allows the user of the
instrument also in criticalzones with heavy jobs.The function“Falseecho storage”assuresthe device to
identify the correct echoalso in presence of false ECHO, supplying correct measures. The integrated
temperaturesensor puts into effecta temperaturecompensation in realtime.
