1. Product Description
1.1 Features
The MRF-10 is a loop-powered radar level gauge, which can be installed easily in a
variety of applications. The MRF-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.
MRF-10 uses 5.8GHz low power pulsed microwave. It provides good measurement
stability, because propagation of microwaves is less affected by change of temperature,
pressure or gas conditions in tank.
1.2 Measuring Principle
The MRF-10 level gauge utilizes the time-of-flight
measurement principle involving short microwave
pulses. Installed at the top of tanks or channels, it emits
short microwave pulses toward liquids or pastes.
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).
1.3 System configuration
MRF-10 can be configured with remotely from a personal computer via a modem or a
handheld terminal.
The MRF-10 is required to connect to a PLC or power supply unit.
