GENERAL INFORMATION
IMPORTANT
First and foremost it is essential that this manual be read and understood before
installation and start up of the MultiRanger Plus.
"Applications" provides a general description of the common applications found in
industry and illustrates them with examples. It is suggested that you refer to the
sub-section which most suits your application. The programming of the MultiRanger
Plus can be optimized by referring to Parameter Description or Appendices \
Alphabetical Parameter Listing.
THE MULTIRANGER PLUS
The MultiRanger Plus is a multi-purpose level monitoring system consisting
of a MultiRanger Plus in a CSA type 4 enclosure, a programmer and an
ultrasonic transducer.
The MultiRanger Plus emits an ultrasonic pulse via the transducer. The echo is
reflected from the material and received by the transducer. The echo is processed by
the MultiRanger Plus and the time at which the ultrasonic pulse hits the level or target
is extracted and compared to the time at which it was sent. The time differential is
then converted into distance, material level, volume, flow or differential level as a
basis for display, relay control, analog output and totalling.
As well as simple level measurement, the MultiRanger Plus was designed to handle
specific applications such as: pumped volume totalling, differential level and open
channel flow measurement.
