Dynasonics” DFX Doppler ultrasonic flowmeter features intelligent software algorithms to monitor incoming signal quality and flowmeter performance — both during initial startup and continuously during operation — making automatic adjustments to nullify changing liquid conditions. Installation can be performed without special tools, training, or specialized software. The Series DFX is built on the same framework of the Series TFX transit-time ultrasonic flowmeter. Features common to the TFX and DFX system include: NEMA 4X [IP66] enclosure, field replaceable isolated output modules, large character backlit LCD, auto-ranging rate display, and impedance-matched ultrasonic transducer connections. The DFX also includes a digital mixer circuit that is resistant to measurement errors caused by electrical noise and other ultrasonic products. The clamp-on pipe transducer is rated to NEMA 6P [IP68], supports temperatures up to 400 F (200 C), and can be located up to 1,000 feet from the DFX display enclosure. An insertion probe transducer is available for installation on pipe systems that do not permit ultrasound penetration. The system can measure flow on pipe sizes larger than 1/8 inch [3 mm] and flowrates from 0.15 to greater than 30 FPS (0.05 to 9+ MPS).
