Dynasonics DT9 Remote Doppler Transducer Sets
The DFX flow meter operates by transmitting ultrasonic sound from its transmitting transducer through the pipe wall into the flowing liquid. Each transducer contains piezoelectric crystals to transmit this signal. The sound will be reflected by useful sonic reflectors suspended within the liquid and recorded by the receiving transducer (see Figure 1). If the reflectors are moving within the sound transmission path, sound waves will be reflected at a frequency shifted (Doppler shift) from the transmitted frequency. The difference between the reflected frequencies and transmitted frequencies is directly proportional to the speed of the sonic reflectors, resulting in a liquid flow rate that is converted to various user defined measuring units.

All DT9 transducers include acoustic couplant. DT94 includes four (4) 36 in. (890 mm) mounting straps.
DT9 transducer sets mate with DDFXD Transmitters.
