SYNCHRONIZATION
Synchronization may be required to prevent interference (readings with no flow or "cross talk") in
applications where more than one DFM 5.0 Doppler sensor is used in close proximity. Synchronize
DFM 5.0 flow meters only if sensors from separate DFM 5.0 flow meters are mounted on the same pipe.
To synchronize one or more DFM 5.0 flow meters use twisted, shielded pair cable, 22AWG or heavier.
Connect SYNC + of one DFM 5.0 to the SYNC + of the next unit. And connect SYNC - of one DFM
5.0 to the SYNC - of the next unit, etc. Connect shield to Transducer GND on all units as illustrated
below.
No changes in DFM 5.0 hardware setup or software are required. The instruments manage
synchronization connections automatically.
