MADECO Smart Radar Water Level Meter
Operating Instruction
Model : MDRA9
Chapter 1 Product Overview
1.1 Introduction
80G radar water level gauge is a high-precision radar water level measuring instrument. It uses 80G
millimeter radar waves as the carrier signal. Based on the leading patented sensor technology and
microsecond time resolution, it achieves millimeter-level measurement accuracy, and the measurement
results are more accurate and stable. Radar sensors are highly robust against any natural sources of
interference such as noise, dust, color, direct or scattered light.
1.2 Principle
The high-frequency radar pulse wave emits narrow microwave pulses, which are transmitted downward
through the antenna. After the microwave pulses touch the surface of the measured medium, they are reflected
back (ie, echo pulses), and are received again by the antenna system and transmitted to the electronic circuit
part. Automatically convert to water level signal. (Because microwaves travel so fast, the time it takes for the
microwaves to reach the target and reflect back to the receiver is almost instantaneous.)

If it is affected, a new false echo needs to be created to remove interference for measurement.
