Positive Displacement Flowmeter

More About Positive Displacement Flowmeter -

• Product Description -

  • Measurement Principle: Mechanical displacement of fluid volume using gears, pistons, or lobes
  • Direct volume measurement – high accuracy independent of fluid properties
  • Handles high-viscosity media such as oils, syrups, and fuels
  • No straight pipe run required – suitable for tight installation spaces
  • Excellent repeatability for batching and custody transfer applications
  • Mechanical versions require no power supply
  • Optional pulse or analog output for connection to displays or controllers
  • Bidirectional measurement capability (model dependent)
  • Compact and rugged design for both portable and fixed installations
  • Low maintenance with simple mechanical parts
