FOXBORO FMB231 Mass Flow Meter

Product Dimensions：

Foxboro (Schneider Electric) Mass Flow Meters are precision Coriolis instruments designed to measure fluid mass flow rate, density, and temperature directly, providing multivariable monitoring without requiring external pressure or temperature compensation.

Product Detailed Description

The Foxboro Coriolis Mass Flow Meter system pairs a flow sensor (such as the CFS10, CFS20, or CFS300 series) with a digital transmitter (such as the CFT34A or CFT51). Operating on the Coriolis principle, fluid passing through vibrating tubes creates a phase shift directly proportional to mass flow. The digital transmitter converts these signals into high-precision measurements while continuously filtering out line noise and entrained gas interference.

Product Advantages

• Direct Multi-Variable Output: Simultaneously outputs mass flow, volume flow, fluid density, and process temperature over a single fieldbus or analog signal.
• Entrained Gas Management: Digital processing algorithms maintain measurement stability even during two-phase (liquid/gas) flow conditions without stalling.
• No Moving Parts: Low maintenance with minimal mechanical wear, eliminating the need for routine recalibration typical of volumetric meters.
• Immunity to Flow Profiles: Does not require straight pipe runs upstream or downstream for accurate installation.

Important Considerations (Precautions)

• Pipe Stress & Vibration: Mount the sensor securely on rigid pipe supports to prevent external plant vibration from interfering with the tube frequency.
• Entrained Air Avoidance: Position the sensor at low points in liquid piping runs (or maintain sufficient backpressure) to prevent gas pockets from forming inside the sensor tubes.
• Zero-Point Calibration: Always perform a field zero-point adjustment under actual operating temperature and pressure conditions with full pipes and zero flow.
• Corrosion & Erosion Limits: Ensure fluid properties are compatible with selected wetted materials (316L vs. Hastelloy) to prevent tube degradation.

Product Applications

• Custody Transfer: High-accuracy batching and fiscal metering in oil refineries, fuel terminals, and chemical loading stations.
• Chemical & Pharmaceutical Processing: Dosing, reaction monitoring, and continuous blending of high-cost reagents.
• Food & Beverage: Concentration measurement, density monitoring (Brix/Plato), and sanitary batching.
• Power & Energy: Fuel oil monitoring, burner feed control, and gas metering under variable temperature and pressure.
