PURPOSE:To display flow rate with slight errors continuously and to integrate the flow rate by detecting the quantitative change in the kinetic energy of fluid in the bend part in the mid-way of a transport pipe as the tension or pressing force exerted upon a load cell. CONSTITUTION:The rectilinearly advancing pressure air fed to this device is compelled to change direction in the part of a bend 1, and tends to displace the bend 1 forcibly outward with a fulcrum axis 8 of the bend as an axis. However, the bend is connected at the front and rear to flexible pipes 4, 5 on the upper and down stream sides; therefore the down stream side of the bend 1 tries to escape to an outer arc side. In accordance with said movement, a suspension fulcrum 9 tends to detach from a load cell 10 and tensile force acts upon the inside of the cell 10, thus generating a strain in the detecting part thereof. When materials to be transported are contained in the pressure air, the intensity of the force pressing the bend to the outer arc side differs from that in the case of the flow of only the pressure air and therefore the magnitude of the tensile force is operated with an electronic device. Then the momentary rate of transportation and the integrated value of flow rate are displayed. |
