dBMACH3 & dB3 with Double Sun Shields Pulsar Flow Transducers
dBMACH3

Pulsar’s full range of ultrasonic transducers can be used for flow measurement however, there are two specific designs that have been specially created for flow applications.

The dBMACH3 is the first ultrasonic transducer with zero effective blanking distance.

Features for the dBMACH3 flow transducer

  • 0 – 2.425m measurement range (0 – 7.95ft)
  • ±1mm accuracy
  • ±0.5 resolution
  • IP68/NEMA 6P
  • ATEX Zones 1 & 2 approval standard. ATEX Zone 0 optional
