NYRD702 1.8GHz Guided Wave Radar Level Meter
The guided wave radar level meter is a level meter 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 level meter is reflected to form an echo and return to the pulse transmitter along the same path. The distance between the transmitter and the surface of the measured medium is proportional to the propagation time of the pulse during that period, and the liquid level height is calculated.

Radar Level Meter Operating Principle
Guided Wave Radar is the kind of measuring instrument that is based on the principle of time travel. The radar wave travels at the speed of light, and its running time can be converted into a level signal by the electronic components. The probe emits high-frequency pulses which spread along the cable, and the pulses are reflected back when they encounter the material surface and received by the receiver inside the meter. The distance signal is then converted to the level signal.

Measurement Range
Symbol explanation:
H---- Measurement range
L---- Empty tank distance
B---- The blind area at the top
E---- The minimum distance between the probe and the tank wall
The blind area refers to the minimum distance between the highest level of the material surface and the measurement reference point.
The bottom blind area refers to the distance near the cable bottom that cannot be precisely measured.
The effective distance is the one between the top blind area and the bottom blind area.
Note:Only when the material level is at between the top and bottom blind areas can a reliable measurement of the material level be guaranteed.
