Chapter 1 Product Overview Introduction Thermo’s Polysonics SX40 Dedicated Doppler 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. In addition, operation of the instrument is enhanced by an Expert System which allows the flowmeter to automatically “learn”...
