Sonic-Pro hybrid ultrasonic flowmeters from Blue-White Industries measure flow rate using either Doppler or Transit Time. Noninvasive clamp-on transducers work with both clean and dirty fluids with a high-capacity flow velocity range of up to 30 fps. The flowmeter can be configured and controlled remotely via RS-232, RS-485, USB or Ethernet. Real-time flow can be viewed remotely and data log files can be downloaded on a Windows PC. 714/893-8529; www.blue-white.com.
