The FD613 Series ultrasonic flow meter features advanced Trans-Phase measuring technology, providing
accurate and reliable flow velocity assessments in closed piping systems. The FD613 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 (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 FD613 Series flowmeter utilizes an advanced Trans-Phase measuring
technique, providing accurate, non-invasive fluid velocity assessment without opening the pipe. The
FD613 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.
