To measure and adjust air flow in air valves, diffusers or grilles accurate measurement of small pressure drop (differential pressure) is often required (usually in the range of -50 to 50 Pa).

Abstract: This paper presents a microfluidic flow sensor for the detections of velocity and viscosity, especially for ultra-low viscosity applications. An etched optic fiber with the diameter of 9 mm ...

Abstract: This paper presents a high precision ultrasonic flow meter, designed especially for thin pipe. As thin pipes have a diameter less than 10 millimeters, conventional clamp-on ultrasonic flow ...

On the coldest mornings, the ritual is almost automatic: start the car, crank the heater, and leave the engine humming while ...
