Ultrasonic flow meters use sound waves to determine flow rates. They can be either Doppler Effect meters or Time-of-Flight meters. Doppler Effect meters measure the frequency shifts caused by fluid ...

Non-Invasive Non-invasive flow meters do not require mounting directly in the process flow and can be used in closed piping systems. Ultrasonic flow meters such as Doppler devices may use this type of ...

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 ...

Accurate industrial fluid flow monitoring via today’s latest transit-time clamp-on ultrasonic flow meters can result in ...

Clamp-on ultrasonic flowmeters. Although users could measure inlet water with a volumetric vortex flowmeter, clamp-on ultrasonic flowmeters are ideal for water flow applications due to their ease of ...
