The FD610 Series ultrasonic flow meter features advanced Trans-Phase measuring technology, providing accurate and reliable flow
velocity assessments in closed piping systems. The FD610 Series utilizes a non-invasive clamp-on transducer which is
placed on the outside of a pipe. Within seconds, the large 18 mm (0.7") LCD provides stable flowrate readings in
feet per second or meters per second. This product operates on metal or plastic pipes containing liquids with more than
100 ppm of 100 micron or larger suspended solids or entrained gases.
PRINCIPLE OF OPERATION The FD610 Series flowmeter utilizes an advanced Trans-Phase measuring technique,
providing accurate, non-invasive fluid velocity assessment without opening the pipe. The FD610 Series utilizes two
piezoelectric crystals contained within one transducer to transmit ultrasonic energy into the fluid stream and receive
back energy reflected off discontinuities (suspended particles or entrained gases) within the moving liquid. Transformations
that result from the energy reflections are processed and converted to a measurement of fluid velocity by the sophisticated
software algorithm. The processor also controls all operations of the instrument from its ultra-efficient battery management
circuitry to a proprietary FIR (Finite Impulse Response) filtration program.
