NYRD801 Non Contact 20m Radar Level Gauge Threaded 6.8GHz Hart Level Sensor Radar Level Measurement of Various Liquids
NYRD801 Radar Level Gauge Working Principle
Input:
The antenna receives the reflected micro pulse and transmits it to the electronic circuit. The microprocessor processes the signal and identifies the echo generated by the micro pulse on the material surface. The correct echo signal recognition is completed by pulse software, and the accuracy can reach millimeter level. The distance D from the material surface is proportional to the pulse time travel T: D=C×T/2(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:
It is set by inputting 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, corresponding to 4-20mA output.
NYRD801 Radar Level Gauge Design Features
The intelligent radar level meter adopts advanced microwave processing technology and unique echo discovery echo processing technology. The product can be applied to various complex working conditions.
The "false echo learning" function enables the instrument to accurately identify the true echo under multiple false echo conditions, so as to obtain accurate measurement results.
