Description
The Liquid Controls M30 is a rotary motion positive displacement meter engineered for high-volume custody transfer of petroleum products, aviation fuels, petrochemicals, and crude oil. Three synchronised rotors operate without metal-to-metal contact, with hydraulic sealing maintained by a stationary boundary layer of liquid — eliminating internal wear and sustaining long-term measurement accuracy across demanding high-flow applications.
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 recommended for this meter size across applicable classes; carbon bearings standard on some sizes — consult factory
