Abstract:
1. A method for measuring the strength of an under-water current comprising the following steps; a. placing the measurement device under water at the desirable depth, said measurement device comprising b. said thermometer measures the temperature of the water and transfer data to said processor, c. said thermistor measures the temperature of said heat conductor and transfer data to said processor, d. said heater heats the said heat conductor to a constant heat, e. after a fixed time, said thermistor measures the temperature of said heat conductor that is affected from said under-water current, and transfer data to said micro processor f. said micro-processor calculating all input data, obtained by steps b to e, and produces the output data, said output data includes the strength of water current, said strength of water current is obtained mainly from the difference in the temperature of the heat conductor affected from said under water current, the stronger the current the faster would be the drop in the temperature.
