FIELD: measurement equipment.SUBSTANCE: bulk material consumption measuring device includes a capacitance transducer with measuring and potential electrodes fixed on a measurement insert made in the form of a pipe from dielectric material and voltage generator, one of the outputs of which is connected to potential electrode of capacitance transducer. When bulk material is absent from measurement insert, capacitor with capacitance equal to capacitance of capacitance transducer is connected to output of voltage generator connected to potential electrode of capacitance transducer and to one of the amplifier's inputs, the other input of which is connected to measuring electrode of capacitance transducer, and output is connected to signal conversion device. Measuring and potential electrodes of capacitance transducer are arranged in the screen housing.EFFECT: improvement of bulk material consumption measurement accuracy.1 dwg |
