DMDF3 Enhanced Portable Doppler Ultrasonic Flowmeter

Features:

  • DMDF3 employs Doppler ultrasonic technologies to measure solid-bearing or aerated liquids in metal or plastic pipe
  • Non-fouling transducer is immune to build-up of grease, paraffin and other coating materials
  • Pipe ranges from 25 to 3050mm, and long straight is not necessary
  • Keypad design for transmitter makes the site setup easy and convenient
  • LCD indicates flowrate & total flow
  • Long-term stability never requires re-calibration and maintenance is free
  • Communication protocols allow direct interface to loggers and control systems
