SFC 332N

The SFC 332N is a 32-bit bi-directional, dual meter run, custody flow computer used in liquid custody pipeline applications.

Fifty (50) previous days, batches, and hours of historical data are stored in full format-type reports, as well as 100 previous audit trail reports and alarms.  Sixteen (16) different product files are user-configurable with easy switch feature, and product scheduling for batch operation is available.

Proving with automatic meter factor implementation is possible using uni-directional, bi-directional, reduced volume, Calibron ™ or Brooks™ type Provers.  Automatic 4-way Valve / Piston Control is a standard proving feature.  Repeatability is checked regularly by the flow computer.

Special real-time Turbine Diagnostic functions are available to detect bent or missing turbine blades, wobble, pulsation or flow cavitation.  A turbine meter signature is generated at different flow rates, and then assessed for changes in fidelity continuously.  A frequency or analog signal can be received from a Densitometer.  

An optional Multivariable Module 205 Sensor may be integrally mounted to the SFC 332N  to allow accurate determination of differential pressure, static pressure, and temperature.

  • Excludes signal deterioration caused by field wiring
  • Easy installation, commissioning and maintenance
  • Low power requirements
  • Highest accuracy – signal and stability
  • Liquid or gas measurement in full compliance with API, AGA and ISO standards
  • Serial link outputs for batching, reporting, proving, etc.
  • Ideal replacement for panel mount flow computers
