In a new study, researchers demonstrate long-term, non-invasive monitoring of blood sodium levels using a system that combines optoacoustic detection with terahertz spectroscopy. The paper is ...

Advantages of Ultrasonic Sensors in Liquid Flow Measurement Ultrasonic sensors offer the advantages of being readily available, easy to install (do not have any moving parts), and contactless ...

1. Transit-Time Flow Meters: These measure the time it takes for an ultrasonic wave to travel a set distance with and against the flow direction. 2. Doppler Flow Meters: These utilize the frequency ...

This article presents a new ultrasonic mass flow meter that has only two transducers. The mass flow is inferred from volumetric flow and density. Each of the transducers is an ultrasonic densitometer ...

Top Ultrasonic Flow Meters in the Market While the market for global ultrasonic flow meter is expected to reach USD $ 2 Billion by 2024, the market has witnessed strong growth in the past few years, ...

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 arrays with resonant frequency of ...

In 1959, a Japanese physicist, Shiego Satomura, designed an ultrasonic flowmeter for use in blood flow analysis. It was not until four years later that the earliest ultrasonic flowmeters for ...

Emerson has released the Daniel™ T-200, a titanium-housed transducer, for its gas ultrasonic flow meter product line, marking the first use of metal 3D printing to enhance the acoustic ...

No other gas ultrasonic transducer can be extracted under pressure without special tools and with so few parts to remove or touch in the removal process. The new design is rated for a wide range of ...
