Description Non Contact Type Radar Level Transmitter Liquid Level Meter Radar
Level Switch
The guided wave radar level gauge is a radar level gauge based on
the principle of time domain reflection (TDR). The electromagnetic
pulse of the radar level gauge propagates along the steel cable or
probe at the speed of light. Part of the pulse of the liquid level
gauge is reflected to form an echo and returns to the pulse
transmitting device along the same path. The distance between the
transmitting device and the surface of the measured medium is
proportional to the propagation time of the pulse in between, and
the liquid level height is calculated.
Input: The reflected pulse signal is transmitted to the electronic
circuit part of the instrument along the cable, and the
microprocessor processes the signal to identify the echo generated
by the microwave pulse on the surface of the material. The correct
echo signal identification is completed by intelligent software,
and the distance D from the material surface is proportional to the
time travel T of the pulse:
D=C×T/2 where C is the speed of light
Since the distance E of the empty tank is known, the material level
L is: L=E-D
Output: Set by entering empty tank height E (= zero point), full
tank height F (= full scale) and some application parameters, the
application parameters will automatically adapt the instrument to
the measurement environment. Corresponds to 4-20mA output.

Advantages of Non Contact Type Radar Level Transmitter Liquid Level
Meter Radar Level Switch
The technical advantages of the guided wave radar level gauge: the
radar level gauge measures the continuous level of liquids,
particles and slurries. The measurement of radar level gauge is not
affected by medium change, temperature change, inert gas and steam,
dust, foam, etc. The accuracy of the radar level gauge is ±1mm, the
range is 60 meters, the high temperature of 250 degrees, and the
high pressure of 40 kilograms are resistant. The radar level gauge
is suitable for explosion-hazardous areas.
