What Is an Electromagnetic Flow Meter?

An electromagnetic flow meter is an industrial instrument used to measure the volumetric flow rate of an electrically conductive liquid passing through a pipeline.

The meter operates without a turbine, paddle, restriction plate or other moving obstruction inside the flow path. Instead, it measures liquid velocity using a magnetic field and electrodes installed around the flow tube.

When a conductive liquid moves through the magnetic field, an electrical signal is generated. The electrodes detect this signal, which is related to the velocity of the liquid flowing through the measuring tube.

The measured velocity can then be used by the flow-meter electronics to determine the flow rate through the pipe.

Because the method depends on electrical conductivity, the liquid must be conductive. The instrument is not intended for measuring gases and is unsuitable for non-conductive liquids unless their conductivity meets the applicable meter requirement.

Product Overview

The Electromagnetic Flow Meter is intended for applications involving electrically conductive fluids.

Suitable media may include:

• Water

• Wastewater

• Sewage

• Milk

• Slurries

• Dirty liquids

• Compatible corrosive liquids

• Other electrically conductive process fluids

The flow tube has no internal mechanical element projecting into the liquid path. This unobstructed construction helps minimize permanent pressure loss and reduces the possibility of mechanical blockage caused by internal moving parts.

The typical stated accuracy is ±0.5% of full scale.

The primary flow tube can be selected with different electrode and liner materials according to the process medium. Available electrode materials include SS316, SS316L and Hastelloy C, while the internal lining can be supplied in PTFE or hard rubber.

The final configuration should be selected after reviewing the liquid composition, conductivity, media pressure, operating temperature and material compatibility.

Working Principle

The instrument works on the electromagnetic principle of flow measurement.

A magnetic field is created across the measuring tube. When an electrically conductive liquid passes through this magnetic field, a voltage is generated across the liquid.

Electrodes mounted in the flow tube detect the generated signal. The signal changes according to the velocity of the liquid moving through the pipe.

The flow-meter electronics use this measured signal to determine the liquid-flow rate.

Since the measuring principle does not require a rotating or obstructing element inside the pipe, the liquid can pass through the meter with minimal restriction.

This operating principle makes the instrument particularly useful where the process contains:

• Suspended solids

• Dirty liquids

• Wastewater

• Sewage

• Slurry

• Fluids that could affect mechanical flow-meter components

Correct measurement depends on the liquid having sufficient electrical conductivity and the measuring tube remaining properly filled during operation.

Advantages of an Electromagnetic Flow Meter

Unobstructed Flow Path

The flow tube does not contain a mechanical obstruction in the main liquid path.

This allows the liquid to move through the meter in a manner similar to its flow through the connected pipeline.

The unobstructed design is beneficial for liquids containing suspended matter or solids that could otherwise collect around a mechanical measuring element.

Negligible Pressure Drop

Because the measuring tube does not create a major restriction, the permanent pressure loss across the instrument is negligible.

This can be advantageous in pumping and process systems where maintaining line pressure is important.

A low pressure drop can also reduce the additional pumping effort associated with restrictive flow-measuring technologies.

Suitable for Clean and Dirty Liquids

The instrument can measure both clean and dirty conductive liquids.

It may therefore be selected for applications involving:

• Clean process water

• Wastewater

• Sewage

• Milk

• Slurries

• Compatible corrosive fluids

The exact construction must be selected according to the medium.

No Moving Measuring Parts

The flow-measuring section does not depend on rotating mechanical components.

This avoids issues associated with mechanical wear of turbines, rotors or paddles within the liquid stream.

Actual maintenance requirements still depend on the process, lining condition, electrodes, installation and operating environment.

Typical Accuracy of ±0.5% F.S.

The stated typical accuracy is ±0.5% of full scale.

This provides plant engineers and project buyers with a defined performance reference when evaluating the meter for their flow-measurement requirement.

The final performance should be reviewed against the selected model, range and approved product documentation.

Limited Additional Influence from Viscosity

The effect of liquid viscosity on flow through the meter is essentially similar to the effect of viscosity on flow through the pipeline itself.

The instrument does not rely on a freely rotating internal measuring part whose movement could be directly restricted by viscosity.

Useful for Slurry Applications

An unobstructed flow path can be useful when measuring compatible conductive slurries.

Material selection remains important because the liner and electrode surfaces may be exposed to chemical or mechanical wear depending on the nature of the slurry.

Broad Industrial Application

The meter can be used across industries handling conductive process liquids.

Its application range includes water, wastewater, dairy liquids, chemical fluids, sewage and slurry-handling systems.

Limitations and Disadvantages

Not Suitable for Gas Measurement

The magnetic measuring principle is intended primarily for liquids.

The meter does not work effectively for measuring gas-flow rate and should not be selected as a gas flow meter.

Applications involving compressed air, natural gas, process gas or other gaseous media require a different flow-measurement technology.

Liquid Must Be Electrically Conductive

The process liquid must have sufficient electrical conductivity for the electrodes to detect the generated flow signal.

Non-conductive fluids cannot normally be measured using this principle.

The conductivity of the liquid should therefore be confirmed before selecting the instrument.

Material Compatibility Must Be Verified

The flow tube, electrodes and liner are exposed to the process conditions.

The chosen electrode and lining materials must be compatible with:

• Liquid composition

• Chemical concentration

• Operating temperature

• Pressure

• Abrasive content

• Cleaning chemicals

• Process contaminants

SS316, SS316L, Hastelloy C, PTFE and hard rubber have different application characteristics. Selection should be based on the actual process medium rather than general preference.

Correct Installation Is Important

Measurement performance can be affected by improper piping arrangement, incomplete pipe filling, trapped air, disturbed flow or unsuitable electrode orientation.

The meter should be installed according to the approved manufacturer instructions and engineering practice.

Primary Flow Tube Construction

The primary flow tube is the section installed directly in the process pipeline.

Its main construction elements include:

SS304 Flow Tube

The pipe is manufactured from non-magnetic SS304.

The supplied specification states that the pipe is provided without painting.

The non-magnetic construction is relevant to the electromagnetic measuring arrangement.

Electrode Options

Available electrode materials include:

• SS316

• SS316L

• Hastelloy C

The electrodes are in contact with the process liquid and detect the measurement signal generated during flow.

The electrode material should be selected according to chemical compatibility with the liquid.

Inner-Lining Options

The measuring tube can be supplied with:

• PTFE lining

• Hard-rubber lining

The liner separates the process liquid from the main metal body of the flow tube and forms part of the wetted construction.

The correct liner should be selected according to process temperature, chemical compatibility and service conditions.

Carbon-Steel Coil Housing

The coil housing is manufactured from carbon steel and finished with polyurethane paint.

The housing protects the electromagnetic coil assembly around the flow tube.

Media Pressure and Temperature

The stated maximum media pressure is:

20 kg/cm²

The stated media-temperature range is:

0°C to 120°C

Both parameters must be considered during technical selection.

The normal operating pressure, maximum pressure, process surges and test conditions should remain within the approved pressure rating.

Similarly, the operating, cleaning and temporary process temperatures must be considered when selecting the liner and electrode construction.

The meter should not be exposed to pressure or temperature beyond the approved specification.

Applications

The Electromagnetic Flow Meter can be used for precise measurement of electrically conductive liquids in industrial pipelines.

Typical applications include:

• Water-flow measurement

• Wastewater-flow monitoring
