Advanced Microprocessors Guided Wave Radar Level Meter For Complex
Applications
Working principle of Advanced Microprocessors Guided Wave Radar
Level Meter For Complex Applications
The anti-corrosive and microwave pulse emitted by the guided wave
radar propagates along the detection component (steel cable or
steel rod), and encounters the tested media. Due to the sudden
change of the dielectric constant, it causes reflection, and a part
of the pulse energy is reflected back. The time interval between
the transmitted pulse and the reflected pulse is proportional to
the distance of the measured medium.
Input processing
Guided wave radartool that is a measuring equiptment aimed at the
relation of time travel. The 701 thread & flange Anti-Corrtsion wave guided radar wave runs at the speed of light, and the moving
time can be converted into purpose level signal by electronic
components. The wise anf fuctional probe emits highly-frequency
pulse and propagates along the cable or rod probe.
Output processing
By entering empty position like a tank height E(= zero), full tank
height F(= full range) and some application parameters, the
application parameters will automatically and dy adjust the meter
to the measuring environment, corresponding to 4-20mA output.
Design features of Advanced Microprocessors Guided Wave Radar Level
Meter For Complex Applications
◎Guided wave radar object level meter attempts advanced microwave
processing technology and unique Echo Discovery Echo processing
technology, contacting measurement, highly-accurated measurement,
more accurate measurement. Besides, which is guided wave radar is
not affected by external environment such as medium temperature and
adhesion.
◎The 70-X series guided wave radar object level meter is suitable
for versatile complicated working conditions and applications due
to the versprocess connection modes and detection module types. For
instance: high temperature, highly-pressured and low dielectric
constant medium.
◎Pulse working moder, low emission power, can be installed in a
large variety of corrosive, non-metal containers and non stainless
steel no harshness to human body and the surroundings around.
