PRINCIPL E OFOPERATION The M odel300/301isa versatilesystem thatutilizesnon- contactultrasonic technologyto measure liquid levelsina varietyof applications.The system consistsof a transmitter and an ultrasonictransducer.Th e transducercontainsa piezoelectriccrystalthathas the ability to convertelectrical signalsgeneratedby thetransmitterintoultrasonicpulses. The unitoperatesby directing ultrasonicpulses,or sound waves,through the airtoward the liquidsurface.They are thenreflected offtheliquidsurfaceas an echo,and returned tothe transducer.The piezoelectriccrystalthenconvertsthe returned echo intoan electricalsignalwh ichisanalyzedby thetransmitter.Th e elapsedtimebetween thegenerationof the ultrasonicpulse and the return echo isproportionalto thedistancebetween thefaceofthetransducerand theliq - uidsurface. UNP ACKING Unpack the instrumentcarefully,m akingsureallcomponents have been remo ved from the packing material.Inspectall com ponents,and reportany dam age tothecarrierwithin24 hours.Check the contentsof the carton,making sure it agrees withthe packing slipand the purchase order.Verify thatthe m odelnum ber imprinted on thenameplate matches the num ber on the packing slipand the purchase order. R eportany discrepanciesto the factory.Check and record the serialnum ber forfuturereference when orderingparts.
