Thermo Scientific™

SX40 Dedicated Dual Frequency Doppler (DFD) Flowmeter

Reduce errors in the flow measurement of fluids containing particulates by combining Dual Frequency Doppler (DFD) technology with digital signal processing. The Thermo Scientific™ SX40 flowmeter generates two independent ultrasonic signals at different frequencies. By correlating these frequencies, the instrument automatically identifies and eliminates noise errors from sources such as variable frequency drives.
