Description
The Liquid Controls M25 is a rotary positive displacement meter designed for high-capacity custody transfer of refined petroleum and aviation fuels. Its three-rotor design eliminates metal-to-metal contact, preserving measurement integrity while reducing maintenance. Engineered for flows up to 300 GPM, the M25 is built for demanding industrial fuel transfer environments.
Features
- No metal-to-metal contact in the measuring chamber — no wear, sustained accuracy, fewer recalibrations
- Low pressure drop — operates on gravity flow or pump pressure
- Wide temperature range: −40 to +85 °C (−40 to +185 °F)
- Aluminum body construction
- Seal options: Buna-N or Viton® (as specified by catalog number)
- Ni-Resist bearing material standard for both meter classes; carbon bearings standard on some sizes — consult factory
