ABOUT THE AIRANGER DPL PLUS
The AiRanger DPL Plus is to be used only in the manner outlined in this instruction manual.
The DPL+ includes the features of the successful "Milltronics AiRanger DPL" (1988 to 1994) PLUS a variety
of new features, incorporating advances in electronic component, manufacturing, and software technology.
This microprocessor based level monitor is designed specifically for bulk solids and liquid level measurement
applications. A DPL+ level monitor, utilizing a single Milltronics ultrasonic transducer (ordered separately),
accurately monitors vessel material level without material contact. By using an additional transducer, the
DPL+ can monitor the material level in two vessels.
The DPL+ 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
DPL+ measures the time from the pulse emission, to receiving the reflection (echo) from the material. Using
the time measured, the DPL+ 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 automatically compensated. For
superior air temperature compensation, individual Milltronics TS-3 temperature sensors may be used for
each vessel. A simple calibration feature compensates for
homogeneous (consistent composition)
atmospheres other than air.
The DPL+ is capable of monitoring wheat in 60 m (200 ft) high silo’s, 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 DPL+
provides outstanding measurement accuracy, usually within 0.25% of range.

PL-508 6

The distance calculation may 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
Liquid Crystal Display (LCD).
The relays and mA outputs may be used as preset (or programmed as desired) to activate alarms and/or
operate remote monitoring equipment and/or process control equipment.
As well, the DPL+ may be connected to a Milltronics
BIC-II (Buffered Interface Converter) to provide
RS-232C and/or RS-422 communications for host computers, Distributed Control Systems, and
special
(capable of operating as a host device) Programmable Logic Controllers.
Operator programming is accomplished using a Milltronics infrared programmer and is stored in non-volatile
memory, unaffected by power interruption. The infrared interface permits one programmer to be used for any
number of DPL+ level monitors. Upon programming completion, the removable programmer may be locked
away, thereby securing all programming.
While the DPL+ is typically used to monitor material level in open or closed vessels, any process which
requires a distance measurement (within the system range) is a candidate for DPL+ application.
Refer to Application Examples for detailed descriptions of a small sample of
process measurement requirements to which the DPL+ may be applied. If process or equipment position
monitoring at distances greater than 60 m (200 ft) is required, refer to Example - 6, Tripper Measurement.
Throughout this manual (unless stated otherwise) references to material level also apply to any material or
object surface to be monitored by the DPL+.

INSTALLATION
Installation shall only be performed by qualified personnel,
and in accordance with local governing regulations.
The following procedure applies to all DPL+ level monitor installations. See
Application Examples for additional installation requirements. Also, refer to the instruction manuals of all other
equipment connected to the DPL+ for additional installation instructions.
AIRANGER DPL PLUS
Installation should only be performed by qualified personnel, and in accordance with all governing regulations.
LOCATION
Inspect all potential mounting locations. Choose a location suited to the DPL+ polycarbonate enclosure and
the following location recommendations.
The ideal DPL+ mounting location is where the:
1. Ambient temperature is always within -20 to 50 °C (-5 to 122 °F).
2. DPL+ front cover has sufficient room to swing open.
3. Operator and electronics are not exposed to the weather.
4. Cable length requirements are minimal.
5. Mounting surface is free from vibration.
Avoid mounting locations where the DPL+ is:
» exposed to direct sunlight. (Otherwise, provide a sun shield.)
» close to high voltage or current runs, contactors, or SCR control drives.
CABLE/CONDUIT ENTRY REQUIREMENTS
Determine the number of enclosure cable/conduit entries required for:
» Transducers
» TS-3 temperature sensors (if used)
» BIC-II (if used)
» mA outputs (if used)
» Relays (if used)
» Synchronization (see Interconnection\Level System Synchronization)
» Power
Transducer cables must be run in a grounded metal conduit, separate from
other wiring, (except TS-3 temperature sensor wiring, if applicable).
