The senor utilizes TDR (Time Domain Reflectometry) technology. It is best described as low‐energy, high‐
frequencyelectromagneticimpulses,generatedbythesensor’scircuitrythatispropagatedalongtheprobeas

the measurementsare non‐linearor have reducedaccuracy. Therefore,itisnotrecommendedtoactually

dielectricconstant)oftheliquidtobemeasured.
TheMeasurementRange ofLVRD10seriesextendsbetweenthetopand
bottomdeadbandareas;thisistheareainwhichasensorwillhavethe
specified measurement performance. It is recommended that the
maximumand minimumlevels to bemeasured inthetank areactually
within theMeasurement Range ofthe sensor. The span betweenthe
lower range value [4mA] and the upper range value [20mA] of the
current output is proportionally equal from 0 to 100% of your
continuouslevelmeasurementreading.Itisrecommendedthatthe
span between these two range values stays within the Measurement
Range .

the Top Dead Band is different to the measurement location for the

location of the 20 mA can be adjusted with the Maximum Fill‐Height

LinearTankExample
Note: In the above illustration, 10” of liquid will
always be equal to 100 gallons of liquid (1” = 10
gallons).

They should neither touchnor swaytowards otherobjects insidethetankorthetank/nozzlewalls;e.g.by
agitator or mixer swirls. In applications with very strong fluid movements which can also cause excessive
lateral force on the probe, it is recommended to anchor the probe. The anchoring fixtures are end user

InstallationTips(continued)
Non‐metallictanks
Unlike coaxial, rod and cable probes have no containment
mechanism.Thisenergymustbecontainedbythetankwall,
requiring that all rod and cable probe sensors be installed in
metallictanksorwithinbelowgradeconcretesumps .
Coaxial probes can be installed in any type of tank, including
non‐metallic tanks. This is because the outer tube acts as an
insulatorpreventing thesensor’s energyemanating beyondthe
probe.
StillingWells/BypassChambers
Installations within a stilling well or a bypass chamber are
recommendedwitharodprobe.Ametallicpipeisrequired.Acoaxial
probe can be used in a stilling well or bypass chamber if required.

EMPTYSIGNALSCAN SectionSix
EmptySignalScan
The empty signal Scan is a powerful disturbance signal suppression feature of LVRD10 Series. The sensor
scans its entire probe length for any disturbance/interference signals within the application that could
potentially be misinterpreted as level readings by memorizing and suppressing them during operation.
Therefore,theLVRD10seriesonlyrecognizestheactuallevelsignalscausedbytheliquidbeingmeasured.
