Phase-Sensitive Air Flow Measurement Using PMUTs
Abstract: This paper presents an ultrasound-based airflow measurement using Piezoelectric Micromachined Ultrasonic Transducer (PMUT) transceivers. Two PMUTs are utilized, each with an active area of 0.28 mm 2 (chip size can be smaller than 1 mm × 1 mm), to measure the flow. The proposed flowmeter employs a phase-sensitive …

Air Flow Meter: Definition, Types, Applications and Benefits
An air flow meter is defined as a device that measures the rate of air flow in a duct or pipe. The rate of airflow is also known as the velocity or volume of air. Air flow meters can also measure the pressure and direction of airflow, which are important parameters for some applications. Air flow meters work by using different principles and ...
