Siemens 7ME6140-2RA10-1AA1 SITRANS FM MAG 1100 F Electromagnetic Flow Sensor

Product Overview

The Siemens 7ME6140-2RA10-1AA1 is a SITRANS FM MAG 1100 F full-bore electromagnetic flow sensor designed for accurate measurement of conductive liquids. It is mainly used in food & beverage, pharmaceutical, chemical, and process industries where reliable flow measurement is required.

This model is a remote transmitter type sensor, requiring a compatible Siemens SITRANS FM MAG transmitter (such as MAG 6000 series) for signal processing.

Measuring Principle

The Siemens SITRANS FM MAG 1100 F works based on Faraday’s law of electromagnetic induction:

Conductive liquid passes through a magnetic field → voltage signal generated → flow velocity calculated → flow rate output

The sensor measures volumetric flow without moving parts, reducing maintenance requirements.

Technical Functions

The flow sensor provides:

• Continuous liquid flow measurement
• High accuracy flow detection
• Stable measurement under changing process conditions
• Corrosion-resistant measurement tube design
• Reliable operation in hygienic applications

Suitable for:

• Water
• Process liquids
• Food ingredients
• Pharmaceutical fluids
• Conductive chemical liquids

Features & Advantages

• Original Siemens SITRANS FM component
• No moving mechanical parts
• Low maintenance requirement
• Excellent chemical resistance with PFA lining
• Suitable for hygienic and sanitary applications
• High measurement stability
• Wide industrial application range
• Compatible with Siemens MAG transmitters

Electromagnetic flowmeters are widely used because they can measure many conductive liquids, and the measurement is generally unaffected by temperature, pressure, density, or viscosity changes of the medium.

Applications

Used in:

• Food & beverage production
• Pharmaceutical manufacturing
• Chemical processing
• Water treatment
• Industrial process control
• Automation systems

Typical applications:

• Liquid flow monitoring
• Process control
• Batch production measurement
• CIP cleaning systems
• Utility monitoring

Compatible Equipment

Commonly used with:

• Siemens SITRANS FM MAG transmitters
• Siemens MAG 6000 series transmitters
• Industrial PLC/DCS flow control systems

Important Notes

• 7ME6140-2RA10-1AA1 is the sensor only, not a complete flowmeter system.
• Requires a compatible Siemens electromagnetic flow transmitter.
• Confirm flange size, lining material, electrode material, and process conditions before installation.
• Designed for electrically conductive liquids only.
• Installation direction and grounding must follow Siemens guidelines
