Measuring device for multi-parameters of solid-liquid two-phase flow

Abstract

The invention provides a measuring device for multi-parameters of a solid-liquid two-phase flow, and relates to the technical field of measurement of basic parameters of the two-phase flow. The measuring device comprises a box body and a box cover. A circular opening is formed in the top of the box body, and is matched with the box cover. A measuring mechanism for the heat conduction coefficient and a density measuring mechanism are arranged on the box cover respectively. The density measuring mechanism comprises an ultrasonic transducer fixing seat arranged at the bottom of the box cover andan ultrasonic transducer arranged inside the ultrasonic transducer fixing seat for measuring, wherein an organic glass plate is arranged right under the ultrasonic transducer. The measuring mechanismfor the heat conduction coefficient comprises a glass tube arranged at the bottom of the box cover. A metal platinum wire is mounted on the core of the glass tube, and a wire is arranged on the surface of the glass tube. The wire and the metal platinum wire form a loop for measuring the thermal conductivity coefficient. According to the measuring device for multi-parameters of the solid-liquid two-phase flow, the measuring device has the beneficial effects that multi-parameter measurement, such as density, thermal conductivity, and the like, can be realized; that the structure is simple; and that the measurement result is more accurate.
