Abstract

PURPOSE:To measure the flow of a powdery substance in a short period of time, by providing a plurality of pressure sensors along an outer periphery of a bend portion of a bend pipe in which the powdery substance is flowing, and integrating the pressure of each detected pressure wave in a predetermined time, and obtaining the mass flow based on the integrated sums. CONSTITUTION:n-Pressure sensors 3-1,...,3-n are spaced the same internal one another in an axial direction along the outer periphery of a bend portion 1a. The output of each pressure sensor 3-1,...,3-n is introduced into a pressure gauge 8 where the value detected by each sensor is amplified. An output f1,...,fn of the pressure gauge 8 is inputted to a calculator 9 such as a microcomputer or the like. Since the pressure sensors 3-1,...,3-n are arranged equally at positions where the powdery substance collides against the bend portion, by obtaining the integrated value of each sensor by the calculator 9 for adding operation in the calculator 9, the sum of the integrated values which is proportional to the mass flow of the powdery substance can be obtained.
