A device for measurement of piezoelectric gradient in open channels includes hydrometric rods mounted on floaters and installed in basic points of the channel and geodesic device for determination of water levels in channel by hydrometric rods. Geodesic device is arranged as a horizontal rod with control indicator of its horizontal position to the ends of which nuts are rigidly fixed. The axles of those coincide with basic points of the channel, at that the floaters are made of the same material as two cylindrical bodies with identical constructional parameters, to the lower ends of those cylindrical leads are rigidly fixed, and to the upper ends of the floaters hydrometric rods are rigidly fixed, those are arranged as cylindrical bars with outer thread and scale for determination of vertical level, the bars that go through the nuts of horizontal rod. |
