Ultrasound assisted extraction (UAE) is one of the preferred green extraction techniques
widely used for the extraction of bioactive compounds from plant materials. It has attracted …

Aiming at the problems of substantial pressure loss, small range ratio and contact
measurement in traditional gas flowmeters, this paper designs a new type of data-filtering …

Commercial time-of-flight (TOF) ultrasonic flowmeters (UFM) are rapidly expanding in the
general industry. Among the different techniques that can be applied to determine the TOF of …

Due to the operating conditions, the flow profile within the ultrasonic flowmeters is not
usually uniform. In order to consider the effects of non-uniformity, the flow profile correction …

In this paper, we propose a non-contact ultrasonic liquid flowmeter based on AlN
piezoelectric micromachined ultrasonic transducer (PMUT) arrays. Two 10 by 10 PMUT …

Aerospace explorations stimulate extensive research on innovative propellant flow
measurement technologies in microgravity conditions. Ultrasonic-based measurements …

Feathers, as a byproduct of the poultry industry, present a significant source of keratinous
waste. Conventional methods have been widely used to extract keratin from feathers; …

Based on the transit-time ultrasonic gas flowrate measurement principle, a new model-
based time-of-flight (TOF) measurement method is proposed. The proposed TOF …

This paper addresses wave dynamics confined by an elastic fluid-filled pipeline with a
uniform moving flow. The measurement deviation of an ultrasonic flow meter has been …

Combining the transmission “Z” mode and the reflection “V” mode, a new hybrid dual-path
ultrasonic sensor is designed to make full use of the advantages of the two modes. With the …
