SRZ-H High Resolution Helical Positive Displacement Flow Meter

The SRZ-H High Resolution Helical PD Flow Meters are ideal for high viscosity non-lubricating and abrasive fluids with suspended particulates, such as water-based paints, polymers, glues, and sealing materials, as well as heavy fuel oils. These positive displacement flow meters are equipped with a built-in sensor and are capable of maintaining consistent accuracy of ±0.5% despite changing viscosity conditions.

Key features

  • Measuring Accuracy:
    ±0.5% over full range with 100cP fluid
  • Flow Range:
    0.1 to 10.6 gpm (optional extended range 0.01 to 2.0 gpm)
  • Pressure Rating:
