Abstract
Изобретение относитс к приборостроению , а именно к средствам измерени расхода . Цель изобретени - увеличение точности и ресурса работы расходомера Протекающий через корпус 1 измер емый поток вращает крыльчатку 2, число оборотов которой фиксируетс узлом съема сигнала 3. Измер емый поток создает усилие, действующее на крыльчатку 2. Дл компенсации действующего усили в цилиндрическом обтекателе 4, расположенном за шаровым обтекателем 5 большего диаметра, выполнены каналы 6 В каналах 6 создаетс течение потока, противоположное измер емому потоку , способствующее гидравлической компенсации действующих на крыльчатку 2 сил измер емого потока. Течение потока в каналах 6 создаетс за счет образовани разрежени за шаровым обтекателем 5. 4 илThis invention relates to instrumentation engineering, in particular to means for measuring flow. The purpose of the invention is to increase the accuracy and service life of a flow meter. A measured flow flowing through the housing 1 rotates the impeller 2, the speed of which is fixed by the signal pickup unit 3. The measured flow creates a force acting on the impeller 2. To compensate for the acting force in the cylindrical fairing 4, located Behind the larger-diameter ball fairing 5, the channels 6 are made. In channels 6, a flow is created opposite to the measured flow, contributing to the hydraulic compensation of the wings acting on the wings. 2 heel forces the measured flow. The flow in the channels 6 is created by the formation of a vacuum behind the ball fairing 5. 4 or
