Micronics D550

Contact Instrument Solutions


The Micronics D550 is a portable Doppler flow meter for dirty of aerated liquids. The ultrasonic sensor is clamped onto the outside of a pipe which enables quick temporary measurements to be taken whenever a permanent meter is not required. An acoustic pulse is used which is reflected back to the sensor from particles or gases in the flowing liquid. The flow rate of any fluid can be measured as long as it contains air bubbles or solids. The D550 is ideal for waste water, slurries, sludge and most chemical applications.


  • Single clamp-on transducer
  • Fast, simple operation
  • Rugged, waterproof
  • On board data logger
