INTRODUCTION/TABLEOFCONTENTS StepOne
The small tank sensor is an innovative level sensor family that replaces float, conductance and pressure
sensors that fail due to contact with dirty, sticking and scaling media in small (< 4’/1.25m) to medium
(<18’/5.5m)talltanks.Appliedinskid,machine,toolandprocessapplications, the general purpose sensors
areavailablewithsingleandmulti‐functioncapabilitiesincludingmeasurement,switchingandcontrol.

User’s Responsibility for Safety:OMEGA ENGINEERING manufactures a broad range of level sensing
technologies. While each ofthesesensors is designed to operateina wide variety ofapplications,it is the
user’sresponsibilitytoselectasensormodelthatisappropriatefortheapplication,installitproperly,perform
tests of the installed system, and maintain all components. The failure to do so could result in property
damageorseriousinjury.
ProperInstallationandHandling:Onlyprofessionalstaffshouldinstalland/orrepairthisproduct.Install

WiringandElectrical:Asupplyvoltageof12to28VDC(VACforLVCN414‐Rseriesonly)isusedtopower
the ultrasonic sensor.Electrical wiring of the transmitter should be performed in accordance with all
applicablenational,state,andlocalcodes.
