Description

---

Guided wave radar level gauge 4-20ma water level transmitter is based on the principle of time-domain reflection (TDR) -based radar level gauge, the electromagnetic pulse of the radar level gauge at the speed of light along the cable or probe propagation, when the surface of the measured medium, the radar A portion of the pulse of the level gauge is reflected to form an echo and returns to the pulse launcher along the same path. The distance between the launcher and the surface of the measured medium is proportional to the propagation time of the pulse between them and the height of the liquid level is calculated.

Input: The reflected pulse signal is transmitted along the cable to the electronic circuit part of the instrument. The microprocessor processes this signal to identify the echoes generated by the microwave pulse on the material surface. Correct echo signal recognition by intelligent software to complete, the distance from the surface of the material D and pulse time travel T is proportional to:
D = C × T / 2 where C is the speed of light
Due to the empty tank distance E is known, the level L is: L = E-D
Output: Set by entering empty tank height E (= zero), full tank height F (= full scale) and some application parameters, the application parameters will automatically adapt the meter to the measurement environment. Corresponds to 4-20mA output.
Advantages: Guided wave radar level gauge technical advantages: Radar level gauge liquid, particle and slurry continuous level measurement. Radar level gauge measurement from the media changes, temperature changes, inert gas and steam, dust, foam and so on. Radar level gauge accuracy of 5mm, 60 meters range, resistance to 250 degrees high temperature, 40 kg high pressure, radar level gauge for hazardous areas explosion.
