Micro Motion™ FVM Fork Viscosity Meter
FVM
The Micro Motion™ FVM Fork Viscosity Meter delivers continuous, reliable multivariable measurement of viscosity, density, and temperature through a rugged direct‑insertion design suitable for pipelines, bypass loops, and tanks.
Its hazardous‑area approved, head‑mounted transmitter enables local configuration and display, while advanced internal diagnostics simplify rapid verification of meter health and status.
