1 1 Product Description
The MRG-10 is a loop-powered radar level gauge, which can be installed easily in a variety of
applications. The MRG-10 employs a non-contact radar level gauging principle based on pulsed
microwave signals and is suitable for level measurement in applications such as liquids, pastes and
slurries.
MRG-10 uses 5.8GHz low power pulsed microwave. It provides good measurement stability,
because propagation of microwaves is not affected by temperature, pressure or gas conditions in
tank.
1.1 Features
MRG-10
MRG-10 needs only a two-wire cable for power supply and output signal.
Communication
MRG-10 incorporates HART
®
protocol function which superimposes a digital output signal on the
4-20mA current output signal. Settings can be made by a HART
®
communicator or PC-based setup
software.
Volume calculation function
Volume calculation function is based level measurement of the remaining liquid in the tank and the
formula takes into consideration three tank configurations - spherical, vertical cylinder and horizontal
cylinder. There is also an applicable user-defined 20-step table.
1.2 Measuring principle
The
MRG-10
level
gauge
utilizes
the
time-of-flight
measurement principle involving short microwave pulses.
Installed at the top of tanks, it emits short microwave pulses
toward liquids or pastes in the tank. Reflected microwave signals
from the surface are received by the antenna, and processed by
electronics. The time from transmission to reception is
determined by the microprocessor and converted as distance
from the transmitter to the liquid surface (ullage) with output of
the calculated level from the measured ullage (Level = Tank
Height – Ullage).
