Flow Meter Advantages: Piston Flow Meters vs. Coriolis

Piston Meters out perform Coriolis meters

While both technologies can measure ultra-low flow rates; piston meters are able to accurately track and totalize intermittent flow with no  “zero-drift" and are the leading choice for clean lubricating, or viscous fluids. They are especially popular in fuel measurement applications and chemical additive applications.

Coriolis meters measure the mass flow directly, while a piston meter is a volumetric flow rate device. One form of measurement can be converted to the other by factoring in the fluid density (If the liquid’s temperature range is within a +/- 5°C band, one density can usually be used for all your conversions). Coriolis are often used in larger bulk transfer applications, and in highly acidic fluids in chemical processing or in fluids containing a large amount of debris.

Advantages of Max Piston meters include:

  • Max offers the lowest flow rate capabilities, able to measure down to 0.005 cc/min
  • Our meters were built with a wide operating range allowing one Max meter to replace several competitors
  • Max transmitters produce up to 24,000 pulses/cc to give a finer degree of control
  • Max Meters have fast response to flow changes and user adjustable dither and damping settings
  • Cost! Max Meters are competitively priced and are engineered to last.

Max piston meters have anti-dither capabilities to prevent over reporting of flow in applications that have hydraulic noise or are mounted in an area subject to vibration.
