Welcome To Meacon Automation Co.,Ltd
Radar level meter adopts the measurement method of microwave pulse, and can be normal in the industrial frequency band range, low beam energy, can be installed in a variety of metal, non-metallic containers or pipelines, non-contact continuous measurement
The radar water level sensor antenna transmits a very narrow microwave pulse, this pulse to the speed of light propagation in space, encountered by the measured media surface, part of its energy is reflected back, received by the same antenna. The time interval between the transmitting pulse and the receiving pulse is proportional to the distance from the antenna to the surface of the measured medium. Due to the extremely high propagation speed of electromagnetic waves, the time interval between the transmitted and received pulses is very small (nanosecond order) and difficult to confirm. SUP-RD901 series 26G radar water level meter adopts a special demodulation technology, which can accurately identify the time interval between the transmitted and received pulses, so as to further calculate the distance from the antenna to the surface of the measured medium.

Be installed in the diameter of the 1/4 or 1/6. Note: The minimum distance from the tank wall should be 200mm. Note: ① datum ②The container center or axis of symmetry |
The top conical tank level, can be installed at the top of the tank is intermediate, can guarantee the measurement to the conical bottom |
A feed antenna to the vertical alignment surface. If the surface is rough, stack angle must be used to adjust the angle of cardan flange of the antenna to the alignment surface. (Due to the solid surface tilt will cause the echo attenuation, even Loss of signal.) |
