This Microwave Water Surface Current Meter (MWSCM) is designed for measuring the current speed easily in a river and other open channels without contacting the water. It reduces the risk and improves measurements in floods with extremely fast moving water. It is a high tech current meter which can measure the current speed safely and accurately in any flood condition. Current speed is computed by the measured frequency difference, Doppler Frequency, between the transmitting frequency from the antenna and the frequency to the antenna after reflecting from the water surface. The frequency signal is transmitted through an antenna reflecting from the water surface. The Doppler frequency is calculated by the comparison of the transmitted frequency signal and the received frequency signal. The weak signal is amplified and the speed of water surface is calculated through A/D transformation and FFT. This provides:

Safe and simple measurement of current speed during floods without damage to measurement instruments and danger to personnel and multiple persons required during the measurement. One person can measure speed easily without contacting water.
It can be used with 110 or 220 V or 12V DC battery and is easy to move to the measurement site.
It can measure the current speed of a flood at night since the microwave is not affected by the darkness.
It can save the measured data and transfer it to a personal computer.
