Non Contact Type Radar Level Transmitter Liquid Level Meter Radar Level Switch
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.
