5. Some pipe materials such as concrete pressure pipe and some plastic lined pipes do not allow ultrasound to penetrate to the liquid inside For these applications the DP7 insertion probe will be needed The flow meter operates by transmitting an ultrasonic sound from its transmitting transducer through the pipe wall or from the probe tip into the moving liquid The sound will be reflected by useful sonic reflectors suspended within the liquid and recorded by the receiving transducer If the sonic reflectors are moving within the sound transmission path sound waves will be reflected at a frequency shifted Doppler frequency from the transmitted frequency The shift in frequency will be directly related to the speed of the moving particle or bubble This shift in frequency is interpreted by the instrument and converted to various user defined measuring units What makes a good Doppler reflector The four criteria are The scattering material must have a sonic impedance sound speed difference at least 1096 different from the fluid There must be some particles large enough to cause longitudinal reflection particles larger than 35 micron For a given pipe size the longitudinal reflection must have sufficient energy to overcome the Rayleigh energy wasting scattering caused by smaller particles The reflecting material must travel at the same velocity as the fluid for good accuracy APPLICATION VERSATILITY The DFX flow

Wire up to 14 AWG can be accommodated in the DFX terminal blocks a A switch or circuit breaker is required in the installation b The switch or circuit breaker must be in close proximity of the DFX and within easy reach of the operator C The switch or circuit breaker must be marked as the disconnect device for the DFX DC Power Connections 12 to 28 VDC 7 Watts Maximum FIGURE 3 6 DC POWER CONNECTION 06 DPP UM 00147 02 12 29 MULTIPLE METER INSTALLATIONS The DFX flow meter contains a provision for synchronizing multiple DFX flow meters together Synchro nization is required when more than one DFX flow meter is mounted on a common pipe or header sys tem If meters are not synchronized a phenomena called cross talk can occur between meters which can lead to erroneous readings or no readings at all Cross talk results from the small differences in trans mitted frequency generated from two or more different ultrasonic flow meters By synchronizing the transmitted ultrasonic energy cross talk caused by differences in transmitted frequency is eliminated The DFX synchronization circuit is designed to interconnect up to four DFX flow meters over a cable length of 100 feet 30 meters Utilize 20 22 AWG twisted pair shielded interconnection wire for this pur pose See Figure 3 7 TO SYNCHRONIZE MULTIPLE METERS 1 Remove power from the DFX flow meters 2 Daisy chain connect the EXTernal SYNChronization and GND term
