Introduction

AiRanger DPL Plus

Note:
The AiRanger® DPL Plus is to be used only in the manner outlined in this
instruction manual.
The AiRanger DPL Plus is an ultrasonic long-range level monitoring system for liquids and
solids. AiRanger DPL Plus level monitor uses one or two Siemens Milltronics ultrasonic
transducers (ordered separately) to accurately monitor material level in one or two
vessels without material contact.
The AiRanger DPL Plus transmits electronic pulses to each connected ultrasonic
transducer. The transducer converts the electronic pulses to ultrasonic pulses which are
emitted from the transducer face in a narrow beam. The AiRanger DPL Plus measures the
time from the pulse emission, to reception of the reflection (echo) from the material.
Using the time measured, the AiRanger DPL Plus calculates the distance from the
transducer face to the material.
The distance calculation depends upon the sound velocity within the vessel. When
Echomax transducers are used, variable air temperatures are automatically
compensated. For superior air temperature compensation, individual Siemens Milltronics
TS-3 temperature sensors may be used for each vessel. A simple calibration feature
compensates for homogeneous atmospheres other than air.
The AiRanger DPL Plus uses Siemens Milltronics patented Sonic Intelligence®echo
processing. Sonic Intelligence provides high measurement reliability, regardless of
changing conditions within the vessel monitored. By using ultrasonic echo ranging
principles with Sonic Intelligence and velocity compensation, the AiRanger DPL Plus
provides outstanding measurement accuracy, usually within 0.25% of range.
The distance calculation can be converted to space, material level, material volume,
remaining vessel capacity, differential level, or average level readings. The reading
chosen (and operating data) for each vessel is displayed on the LCD (liquid crystal
display).
