Development of Non-Invasive Ultrasonic Measuring System for Monitoring Multiphase Flow in Liquid Media within Composite Pipeline

Abstract

<span>Process of conveying liquid substance via the pipeline is the most common practice of transferring the liquid from one point to another point. Composite pipeline is becoming an option for liquid conveying purposed (instead of PVC, acrylic or metal) for its durability, longer lifetime and non-corrosive material in comparison with current pipeline. In order to ensure, the conveying process has a smooth flow rate without particle or bubble disturbance that could hinder good process flow, non-invasive monitoring system is always required. The ultrasonic measuring system is one of the monitoring options that could be applied. With proper designed for transmitting and conditioning circuitry, 300 kHz ultrasonic frequencies are found as the optimal frequency needed to penetrate across the composite pipeline with full of liquid. The ultrasonic sensor response is being successfully differentiated between full flow (no material blockage) and with bulk material blockage (dry and wet sand).</span>

Measurement of material volumes in a cylindrical silo using acoustic wave and resonance frequency analysis

“…4, August 2020 : 1585 -1594 1586 measurement of liguid or gas that has smooth flow [10,11] but may not be used for non-flow materials. Ultrasonic flow meter that measures flowrates in pipes can be applied to measure the volumes of liquid or gas remaining in the silo with high accuracy [12,13]. However, due to energy absorptivity at high frequency is easily occurred in porous medium, the ultrasonic flow meter may not be able for measuring the bulk volume of granular or non-liquid materials, such as sand, cement, stone flakes, and grain crops.…”

“…displays the output from the acoustic wave reception system in discrete-time domain, where [] yn and [] xn are measured output and generated input signals, [] G hn, [] S hn, and [] Rhn are impulse responses of acoustic wave-generation, acoustic silo, and wave-reception systems, respectively. By applying Fourier transform, it yields the spectrum equation as(13), where () j Ye  and () j Xe  are the spectra of the output and input signal, frequency responses of the acoustic wave-generation, silo and reception systems, respectively.…”

Design, simulation and practical experimentation of miniaturized turbine flow sensor for flow meter assessment

“…The turbine flow sensor was analysed on its consistency as well as the reliability of the theoretical models in which governs the method the flow sensor works. [13] utilised an ultrasonic sensor to find the right frequency which could penetrate composite pipeline to check for the irregularities in the smooth flowing of multiphase liquid. This shows another specialized method to use flow rate sensor for an industrial environment.…”

Ultrasound Measurement Technique for Validation of Cryogenic Flows

“…Sensors for various fluid physical quantities of fluids are essential for the understanding of the fluid behaviour, for their validation and optimization by computational fluid dynamics (CFD) simulations and for the management of cryogenic liquid propellants in heavy-lift launchers such as the European Ariane rockets [1]. Ultrasound tomography as a non-invasive and non-intrusive system is gaining in importance for the real-time process monitoring in industry [2][3][4] and in research [5][6][7][8]. The novel sensor system is developed for imaging the gas-liquid two-phase flow (such as gaseous nitrogen (N2) and liquid nitrogen (LN2)) inside a pipe by using the ultrasound transmission measurement.…”
