1.1 Unpa cking
Unpackthe instrum entcarefully. Inspectallunitsfor dam age. R eportany concealeddam agetocarrierwithin 24 hours. Check thecontentsofthepacking slip and purchase order. Check and recordthe serialnum berfor futurereference when ordering parts. C aution: Do not discard the shipping container untilallparts are checked.
1.2 Mounting and ApplicationConsiderations
C aution: Un itshouldonly be hand-tightened ( 4– 12 ft-lbs)into the process connection.The w rench flatsshouldonlybe used wh en remo ving the unit.Overtightening willcause trans - ducererrors and w illvoid thew arranty. The reare severalapplication considerationsthatshouldbe evaluated priorto installing a non-contactultrasonictrans - mitter. T he nextfew pagesshouldbe read thoroughlyto ensure thattheM odel335 w illperform asexpected in thegiven application. Section 2.4, M easurementRange Calculations ,providesme asurementrangecalculationsthat shouldbe used todetermine the maximum potentialrange indifficultapplications.
1.2.1 Position
The optimu m m ounting position ofthe Mo del335 is between 1⁄2 oftheradiusand 2 ⁄3 diameterofthe (cylindrical) tank.Thiswillpositionthe unitto minimize any interfer - encethatthe7°beam (3.5° halfangle)haswith the tank wallsorany agitatorbladesthatexistin the tank.

1.2.4 O bstructions
En sure thatno obstacles(e.g., fillpipes,ladders,bracing me m bers,thermome ters,etc.) protrude into theultrasonic beam. A lthough one fixed objectinthe tank canbe blocked outby appropriate program ming,itisadvised to avoid theseobstructions.
1.2.5 Standpipes
In applicationsw herethe materiallevelm aycome intothe deadband,the transducerm ustbe mou nted in a standpipe.

2.2 Theory ofO peration
Non -contactultrasonic me asurem entism adeby emitting an ultrasonic pulse from the transducerand measuring the time required forthe echo toreflectfrom theliquidsur - faceand return tothe transducer. T he pow erfulelectronics me asure thetime oftheround trip pulse and,by know ing thespeed ofsound,calculatesthe distance. Sincespeed of sound istem perature dependent,the transduceralsomeas - uresthetem perature inthevesselto provide com pensation forchanging tem perature. By inputting thetype and geome tryofthe vessel,theintel - ligentelectronicscancalculate the liquidvolume in the vessel.In a similaroperation,theM odel335 can perform open channelflow m easurementby converting the level readinginto unitsofvolume pertime.
