Being able to measure ducted airflow cheaply and non-intrusively, like with this ultrasonic flow meter, could be a big deal for DIY projects and the trades in general. The principle behind the ...

But for a weekend project, [Vinod.S] took the ultrasonic transmitter and receiver from a distance-meter module and used amplitude modulation to send music ultrasonically from his laptop to a ...

Evolving energy policies, smart city initiatives, and advanced metering technologies propel heat meter adoption, while ...

An ultrasonic flow meter measures the flow rate by transmitting and receiving ultrasound. There are two main principles: the transit-time method and the Doppler method. The transit-time method (Figure ...

This is because the source of the ultrasound isn't coming from the ultrasonic meter but from the component being analyzed (e.g. pump bearing, steam trap or high-voltage switchgear). Pulse-echo ...

This repository is used to read data from an Ultrasonic water level meter QDY70A using an arduino. Communication with the ultrasonic sensor is done with the MODBUS protocol. The resulting liquid level ...

I looked at the distributions of all the features data and the value counts for the various categorical variables. Below are a few highlights from the analysis .

Ultrasonic measurement of ONSD can reflect the relative real-time changes in ICP. intracranial pressure lumbar puncture optic nerve ultrasonic measurement This is an open access article distributed in ...

The system has been designed to have ultrasonic technology as well as TOF (time of flight) measurement. The system delivers remarkable performance such as a quick response, no drift, high ...

The new BinMaster ToughSonic TC-100 and TC-200 non-contact ultrasonic sensors include general-purpose and chemical-resistant ...
