A device for measurement of suspension flow velocity at cross section of pipeline includes Pitot-Prandtl tube, total pressure tube, static pressure tube,nozzle and manometer of dynamical pressure. The device has autonomous source for supply of compressed air, pressure value of that one is enough for stable prevention of penetration of falling flow of solid component suspension to receiving channels of the tube, measuring diaphragm for fixation of flow rate of compressed air, air receiver, manometers of total and static pressure, control throttle placed between the manometer of total and static pressure and the autonomous source. |
