Abstract

PURPOSE:To enable measurement of the flow rate of solid particles by a simple constitution by conducting operational processing on the basis of the velocity of air flow on the upstream side of a solid-particle supplying point and on a pressure loss caused by a mixed gas on the downstream side thereof. CONSTITUTION:The solid particles are arranged to be supplied from a solid- particle hopper 1 to a point P on a conveying line 5 and a gas flow meter 6 measuring the velocity Ua of air flow on the conveying line 5 is provided on the upstream side of the supplying point P. Moreover, a differential pressure gage 7 is installed in the static section of a mixed fluid on the downstream side of the supplying point P, and a pressure loss signal DELTAP from the differential pressure gage 7, a signal DELTAPa of pressure loss caused only by air flow and the air-flow velocity signal Ua from the gas flow meter 6 are inputted in an operator 8 and operated on the basis of the formula, whereby the flow rate Gs of the solid particles flowing through the conveying line 5 is found. In this formula, D is the inside diameter of the line 5, g is acceleration of gravity, and K is a parameter to be found by Ua and the diameter of the solid particles.
