Claims (1)

Расходомер жидких сред в открытых водоемах, содержащий уровнемер и блок измерения средней скорости потока жидкости, выполненный на основе отклоняющейся лопасти от вертикали на определенный угол, а также электронный блок приема и обработки сигналов, отличающийся тем, что глубину текущей жидкости от уровня поверхности до дна водоема определяют как сумму двух слоев жидкости, один из которых простирается от уровня поверхности до уровня погружения конца лопасти в процессе измерения скорости потока, а второй слой - от конца лопасти до дна водоема, при этом толщину первого слоя определяют с помощью двух идентичных датчиков давления, электрически сопряженных между собой по разностной схеме, один из которых установлен на конце лопасти, а второй размещен в атмосфере воздуха, глубину второго слоя определяют по углу отклонения лопасти от вертикали с учетом длины лопасти и высоты ее подвеса относительно дна водоема.A liquid flow meter in open reservoirs containing a level meter and a unit for measuring the average fluid flow rate, made on the basis of a deviating blade from the vertical by a certain angle, as well as an electronic signal receiving and processing unit, characterized in that the depth of the current fluid from the surface level to the bottom of the reservoir defined as the sum of two layers of liquid, one of which extends from the surface level to the immersion level of the end of the blade in the process of measuring the flow velocity, and the second layer from the end of the blade to the bottom of the water volume, while the thickness of the first layer is determined using two identical pressure sensors electrically interconnected according to a difference scheme, one of which is installed at the end of the blade, and the second is placed in the atmosphere of air, the depth of the second layer is determined by the angle of deviation of the blade from the vertical, taking into account the length of the blade and the height of its suspension relative to the bottom of the reservoir.
