Sand-carrying fluid density measuring device and method of sand mixing equipment

The invention discloses a sand-carrying fluid density measuring device of sand mixing equipment. A measuring manifold is intercepted from a sand-carrying fluid discharge manifold of a sand mixing vehicle, a casing pipe with the slightly larger latus diameter is arranged on the outer wall of the measuring manifold, different sand-carrying fluid sampling points are selected from the measuring manifold, the sampled sand-carrying fluids flow through independent liquid collecting pipes and enter a collecting pipe, and a mass flowmeter at the rear end of the collecting pipe measures sand-carrying fluid density. The invention also discloses a sand-carrying fluid density measuring method for sand mixing equipment. The method utilizes a multi-layer multi-segment sampling method to measure the density of each layer of the sand-carrying liquid and the density of the mixed sand-carrying liquid of all layers, thereby avoiding the harm caused by the measurement of radioactive elements and saving theuse cost. 本发明公开了种混砂设备携砂液
