AN INSTRUMENTATION SYSTEM FOR MEASUREMENT OF VELOCITY OF SOLID LIQUID AND GASEOUS MATERIALS IN TWO PHASE FLOWS

摘要

An instrumentation system for measurement of velocity of solid, liquid and gaseous materials in two-phase flows, characterised in that the system comprises a measuring unit which is provided with a capacitance sensing probe A, a bandpass amplifier B, a phase-sensitive detector C and an instrumentation amplifier D, such as herein described, and aa interfaced personal computer (PC), such as herewith described, said measuring unit and personal computer being arranged to operate in an inter-connected manner.
