SE-CMF Series

Industrial Coriolis Mass Flow Meter

The SE-CMF Series delivers high-precision 0.1%/0.15% FS accuracy for demanding industrial environments. Direct mass measurement eliminates the need for temperature, pressure, or density compensation. Available with 316L stainless steel, Hastelloy, or titanium alloy wetted parts for compatibility with corrosive media.

How It Works

Coriolis Measurement Principle

VIBRATION (DRIVE MODE) Inlet side Phase shift ∝ mass flow
01

Tube Oscillation

The measuring tubes are driven to oscillate at their natural frequency (typically 80–120 Hz) by a driver coil, similar to a tuning fork.

02

Coriolis Force Generation

When fluid flows through the vibrating tubes, Coriolis forces are induced, causing a measurable phase shift between the inlet and outlet sides.

03

Phase Shift Measurement

Dual electromagnetic sensors detect the time delay (phase difference), which is directly proportional to the mass flow rate — independent of fluid properties.

04

Multi-Variable Output

The DSP calculates mass flow, density, and temperature simultaneously. Density is derived from tube resonant frequency; temperature from an integrated RTD.

Configuration Options

Choose the Right Configuration

Select from multiple material, communication, safety and size options to match your exact process requirements.

Contact Materials

  • IP66/IP68 — Dust-tight and submersible enclosure. Suitable for outdoor, washdown and flood-prone installations.
  • Certificate copies provided with every hazardous-area shipment.

Size & Connections

  • DN1.5–DN6 — Micro-flow series for laboratory, dosing and additive injection (threaded connections).
  • DN10–DN50 — Standard industrial range. Flanged (ANSI/DIN) or Tri-Clamp sanitary connections.
  • DN80–DN250 — Large pipeline series for main process lines, custody transfer and bulk flow.
  • Custom flange ratings from ANSI 150 to 2500 / DIN PN16 to PN420.
