THE MEASUREMENT OF TIDAL WATER TRANSPORT IN CHANNELS

[摘要] For the electromagnetic flow measurement in straits, channels etc use is made of the electric potential difference between two points m the bottom, near the moving water. The potential difference can be put down to natural causes the water is an electric conductor and moves m the magnetic field of the earth There are a number of quantities and variables that are of importance for the measured signal Beside this, the measurement is above all a matter of eliminating some disturbances Information about the two measuring systems as applied m The Netherlands is given m this article.
