Positive Displacement Flowmeters

Positive Displacement flowmeters measure the volume of fluid that passes though the pipe. There are many different types of PD meters, including piston and gear meters. Max piston meters provide the accuracy, flow range and ultra-high resolution normally associated with laboratory measurement devices in a convenient to use, rugged, industrial grade sensor. The Max piston meters have always been the preferred choice for low flow rate and wide range applications. Compare our 0.2% of reading accuracy and ultra wide flow range against any other meter.

Helical screw meters

Helical screw meter - Max H241Helical screw meters are used extensively in Aerospace and are able to measure with precision accuracy. Flow ranges are:

  • 100 cc/min to 189 liters/min (H241)
  • 1 to 500 liters/min (H242)

Gear meters

Gear meters are used extensively with viscous fluids such as hot melt adhesives, and in the automotive sector for hydraulics, coolant and fuel measurement and are able to measure with precision accuracy and the highest resolution on the market. These are available in several ranges as listed below:Max Gear Meter G240

  • 0.5 cc/min to 4 liters per minute (G004)
  • 10 cc/min to 15 liters per minute (G015)
  • 25 cc/min to 45 liters per minute (G045)
  • 75 cc/min to 105 liters per minute (G105)
  • 250 cc/min to 240 liters per minute (G240)

Piston meters

Piston meters provide the lowest and most accurate flow measurements for low viscosity fluids (solvents, oils and fuels) with extremely high resolution. Flow ranges are as follows:Piston Meter - Max P001

  • 0.005 to 200 cc/min (P001)
  • 0.5 to 2000 cc/min (P002)
  • 0.5 to 1800 cc/min (P213)
  • 5 to 10,000 cc/min (P214)
  • 25 to 35,000 cc/min (P215)

Flow Technology also offer a wide range of Positive Displacement meters suitable for high viscosity fluids, sanitary applications serviceable on-site.

Atex approvals and high temperature versions are optional.
