radar level meter

Radar level meter product overview
. Introduction
R radar level meter is an advanced radar level measuring instrument with a maximum measuring distance of meters. It can be used for storage tanks, intermediate buffer tanks or process containers. Level measurement, output analog signal.
. Application
● Use advanced non-contact measurement
● Made of extremely stable materials
● Measure the level of liquid and solid media
● Can measure all Medium with dielectric constant >.
● Measuring range
● Adopts two-wire, loop-powered technology, and the supply voltage and output signal are transmitted through a two-core cable
● Output or digital type Signal output
● Resolution
● Not affected by noise, steam, dust, vacuum and other working conditions
● Not affected by changes in medium density, viscosity and temperature
.Measurement Principle
High-frequency microwave pulses are emitted and received through the antenna system. The radar waves travel at the speed of light, and the running time can be converted into a level signal through electronic components. A special time-stretch method ensures stable and precise measurements over extremely short periods of time.
Even if there are false echoes under complex working conditions, the latest microprocessing technology and debugging software can accurately identify the material level echo.
. Input
The antenna receives the reflected microwave pulse and transmits it to the electronic circuit. The microprocessor processes the signal and identifies the echo generated by the micro-pulse on the surface of the material. Correct echo signal identification is completed by intelligent software, and the accuracy can reach millimeter level. The distance from the material surface is proportional to the time travel of the pulse: (where is the speed of light)
Since the distance of the empty tank is known, the material level is:
. Output
By inputting the height of the empty tank (zero point), full tank height (full scale) and some application parameters to set, the application parameters will automatically adapt the instrument to the measurement environment. Corresponds to the output.
