Electromagnetic Flowmeter Applications
Water & Wastewater
Suitable for raw water, municipal water supply, circulating water, municipal and industrial wastewater, and return activated sludge (RAS). Selection should consider pipe size, flow range, conductivity, temperature, pressure, solids content, abrasion, corrosion, grounding and material compatibility.
Recommended: Standard Electromagnetic Flowmeter
Food & Beverage
The food and beverage industry requires hygienic flow measurement, reliable accuracy, and easy-to-clean instrumentation. ARTang sanitary electromagnetic flow meters are 3-A certified and feature an all-stainless-steel housing, making them well suited for production, batching, filling, blending, and CIP and SIP cleaning lines.
Recommended: Sanitary Electromagnetic Flowmeter
Pulp & Slurry
Fibrous pulp, sludge, mining slurry and tailings may cause signal noise, electrode coating and liner wear during flow measurement.
Dual-frequency excitation and suitable liner and electrode materials help improve measurement stability.
Recommended: Slurry Electromagnetic Flowmeter
Chemical Processing
Strong acids, alkalis, chemical reagents, and high-temperature or corrosive processes require compatible liners, electrodes, and suitable electromagnetic flowmeter configurations. Selection should consider the medium, temperature, pressure, and hazardous-area certification requirements to ensure reliable measurement and long-term stability.
Recommended: Chemical Electromagnetic Flowmeter
HVAC & Energy
Electromagnetic BTU Meter calculates energy consumption by combining flow measurement with the temperature difference between the supply and return pipelines. It is used in chilled-water and hot-water systems, HVAC plants, district heating and cooling networks, and commercial or industrial energy monitoring.
Recommended: Electromagnetic BTU Meter
Large Pipelines & Retrofits
Suitable for large-diameter pipelines, retrofit projects and sites where installing a full-bore meter is difficult or costly. Insertion electromagnetic flowmeters reduce pipeline modification and installation work, while fewer models can cover a wide range of pipe sizes and simplify spare-parts management.
Recommended: Insertion Electromagnetic Flowmeter
How Electromagnetic Flowmeters Work
Measurement Principle
Electromagnetic flowmeters measure conductive liquids based on Faraday’s law. As the liquid flows through a magnetic field, electrodes detect an induced voltage proportional to the flow velocity. The transmitter processes this signal and calculates the volumetric flow rate based on the known cross-sectional area of the measuring tube.
With no moving parts or obstruction in the measuring tube, magnetic flowmeters create no significant pressure loss and require little mechanical maintenance.
Measurement Requirements
Reliable measurement requires sufficient liquid conductivity, a completely filled pipe and stable grounding. Excessive air bubbles, unsuitable flow velocity or incompatible liner and electrode materials may affect measurement performance.
Application Range
Suitable for conductive liquids such as water, wastewater, slurry, pulp, acids, alkalis and conductive food or beverage liquids.
How to Select the Right Electromagnetic Flowmeter
As an electromagnetic flowmeter supplier, ARTang recommends selecting the right model based on fluid properties, process conditions, material compatibility, installation requirements, and signal integration to ensure accurate and reliable flow measurement before quotation.
Process Conditions & Fluid Properties
Start by confirming the measured medium, process temperature, operating pressure, flow rate range, and pipe size to determine the basic electromagnetic flowmeter configuration for your application.
Fluid Conductivity Requirements
Fluid conductivity is essential for magnetic flow measurement. Standard electromagnetic flowmeters are suitable for media above 5 µS/cm, while low-conductivity liquids from 0.8–5 µS/cm may require ARTang pure water magnetic flowmeters.
Liner and Electrode Material Selection
Liner and electrode materials should be selected according to fluid corrosiveness, abrasion, temperature, and pressure.
Nominal Diameter and Connection
The flowmeter size and connection type should match the pipeline size and installation conditions.
Power Supply and Output Signals
Power supply and output signals should be confirmed according to your control system requirements.

FAQ About Electromagnetic Flowmeters
An electromagnetic flowmeter can measure conductive liquids such as water, wastewater, slurry, acid, alkali, chemical liquids, and some food or beverage liquids. It is not suitable for non-conductive liquids such as oil, gas, steam, or pure hydrocarbons.
No. Electromagnetic flowmeters are not suitable for non-conductive liquids such as oil, gas, steam, or pure hydrocarbons.
The lining material should be selected according to the liquid’s corrosion, abrasion, temperature, and hygiene requirements. Common options include PTFE, PFA, rubber, and polyurethane. For corrosive liquids, PTFE or PFA is often considered. For abrasive slurry, wear-resistant lining may be required.
An integrated electromagnetic flowmeter combines the sensor and transmitter in one unit, which is suitable for standard installation. A remote type separates the transmitter from the sensor and is better for high temperature, vibration, flooded, underground, or hard-to-access locations.
Yes. ARTang supports customized electromagnetic flowmeters with different sizes, materials, connections, transmitter types, signal outputs, and installation options.
