ultrasonic vs. differential pressure flowmeters for high .

Ultrasonic vs. Differential Pressure Flowmeters for High .

Ultrasonic flowmeters are linear so accuracy does not degrade at low flow and accuracies are expressed as a percentage of the actual flow rate, and not of maximum range, so their accuracy is dramatically better than that of differential pressure flowmeter systems, especially at mid-range and lower flow rates.
