The article covers the issues of development and the results of the pilot testing of the contact-free meter of the two-phase flow of loose construction materials in the course of their pneumatic transportation. The flow meter designed by the author is based on the method of registration of polarization currents caused by the motion of the dielectric material within the electric field of a measurement unit integrated into the pneumatic transportation line. The registration unit is the implementation of the original technology. Its functional concept is based on the Pockels transverse effect inside the lithium niobate crystal. This electro-optical effect is characterized by minimal persistence, as the phase of the optical wave varies within the time period of 10 second, and this effect makes it possible to improve the accuracy of measurements. The flow rates is identified on the basis of one variable integral parameter, the intensity of an optical wave passing through the Pockels cell simulated by the currents of polarization of the material. The paper contains the structural pattern of the computer-aided meter of loose dielectric materials in the course of their pneumatic transportation, the system of visualization of the mass flow, and the results of the pilot testing of the proposed meter. The proposed system may represent an unbiased system of management of construction materials, consumption procedures, and warehouse processing of materials.
