Description

что поплавок все врем  находитс  на поверхности воды. Гидрометрическа  вертушка 1, расположенна  на одной из боковых штанг, например 7, на рассто нии 0,6 1, где I - длина штанги, при любом уровне должна находитьс  на глубине 0,6 h, где h - глубина в месте установки устройств.that the float is always on the surface of the water. Hydrometric swivel 1 located on one of the side rods, for example 7, at a distance of 0.6 1, where I is the length of the rod, at any level should be at a depth of 0.6 h, where h is the depth at the installation site of the devices.

Гидрометрическа  вертушка 1 вырабатывает дискретные электрические импульсы, которые через преобразователь 2 в виде непрерывного сигнала, пропорционального средней скорости водотока, поступают на один из входов перемножаюпхего устройства 3. Сигналы, пропорциональные значению уровн  воды с выхода уровнемера 4, в зависимости от модул  пропускной способности русла, с помощью функционального устройства 5 преобразуютс  в величину, котора  поступает на другой вход юремножаютего устройства 3, сигнал на выходе которо|о дает величину, пропорциональную уклоп свободной поверхности водотока.Hydrometric spinner 1 generates discrete electrical pulses that, through converter 2, form a continuous signal proportional to the average velocity of the watercourse to one of the inputs of the multiply device 3. Signals proportional to the level of water from the output of the level gauge 4, depending on the capacity of the channel, with the help of the functional device 5 is converted into a value that is fed to another input of the device 3, the output signal of which gives a value proportional to ionalnuyu uklop free surface watercourse.

Преимуществом предлагаемого устройства  вл етс  повышение точности измерени  уклона неустановивщегос  потока примерно на 100/0.The advantage of the proposed device is an increase in the accuracy of measuring the gradient of unsteady flow by about 100/0.
