ABOUT THE AIRANGER XPL PLUS
The AirRanger XPL+ is to be used only in the manner outlined in this instruction manual.
The XPL+ is a microprocessor based level monitor designed specifically for bulk solids and liquid level
measurement applications. An XPL+ level monitor, utilizing a single Milltronics ultrasonic transducer,
accurately monitors vessel material level without material contact. By using an additional transducer for
each vessel, the XPL+ can monitor the material level in up to 10 vessels.
The XPL+ transmits electronic pulses to each scanned ultrasonic transducer. The transducer converts the
electronic pulses to ultrasonic pulses which are emitted from the transducer face in a narrow beam. The
XPL+ measures the time from the pulse emission, to receiving the reflection (echo) from the material. Using
the time measured, the XPL+ calculates the distance from the transducer face to the material.
The distance calculation is dependent upon the sound velocity within the vessel. When Milltronics
ultrasonic/temperature transducers are used, variable air temperatures are independently compensated for
each vessel. For superior air temperature compensation, a TIB-9 card may be used with individual Milltronics
TS-3 temperature sensors for each vessel. A simple calibration feature compensates for
homogeneous
(consistent composition) atmospheres other than air.
The XPL+ is capable of monitoring wheat in 60 m (200 ft) high silos, acetone in 45 gallon barrels, or almost
anything in between, in any combination. (Ensure the transducer selected for each vessel suits the material
and measurement range required).
This material and measurement range versatility is accomplished by utilizing Milltronics patented Sonic
Intelligence
TM
. Sonic Intelligence provides high measurement reliability, regardless of changing conditions
within the vessel monitored.
By utilizing ultrasonic echo ranging principles with Sonic Intelligence and velocity compensation, the XPL+
provides outstanding measurement accuracy, usually within 0.25% of range.
