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.
