Electromagnetic flowmeters (EMFs) play a vital role as critical measurement instruments in process control, energy management, and environmental monitoring. Consequently, selecting and deploying the right flowmeter can be a complex and challenging task.
Key selection factors include: media conductivity ($\ge 5\ \mu\text{S/cm}$, or as low as $2\ \mu\text{S/cm}$ for advanced low-conductivity models), liner materials, pipe diameter and flow velocity, straight pipe run requirements, compact vs. remote structures, IP protection ratings, explosion-proof certifications, operating conditions, power supply options, and communication protocols.
To simplify your selection process, we have outlined key technical parameters below for your reference.

Classification of Electromagnetic Flowmeters
An electromagnetic flowmeter is a flow instrument based on Faraday’s law of electromagnetic induction to measure the volume of conductive fluids.
Since its main structure consists of two parts—a sensor and a converter—with no moving parts and no pressure loss, it is unaffected by fluid density, viscosity, temperature, and pressure. Featuring a wide measurement range and a large turndown ratio, it can measure highly corrosive media as well as dirty slurry media containing solid particles or fibers. Therefore, it has a wide range of application fields, such as water treatment, chemical, pharmaceutical, metallurgy, and energy & power industries.
To meet the requirements of different operating conditions, many classifications have been developed.
Below is a breakdown categorizing electromagnetic flowmeters by operating conditions, product types, structural characteristics, and typical applications.
| Operating Condition / Environment | ประเภทสินค้า | Key Structural & Design Features | Typical Applications & Industries |
| Standard Industrial Facilities / Ample Space | Compact / Integrated Type (Compact Electromagnetic Flowmeter) | Sensor and transmitter (display) are integrated into a single unit. Easy installation, compact footprint, and highest cost-efficiency. | Ambient-temperature indoor plants, water treatment workshops, standard accessible pipelines. |
| High Temperature / Vibration / Overhead / Pits | Remote / Split Type (Remote Electromagnetic Flowmeter) | Sensor and transmitter are separated and connected via double-shielded cable (up to $100\text{m}$). Transmitter can be mounted in an easily accessible, safe location. | High-temp chemical lines ($>65^\circ\text{C}$), elevated pipe racks, underground meter pits, high-vibration pump rooms. |
| Underground Pits / Flooding Risks / Submerged | Submersible Type (IP68 Waterproof Flowmeter) | Fully sealed sensor housing with potting compounds in the terminal box achieving an IP68 ingress protection rating. Suitable for continuous underwater operation. | Urban drainage networks, underground valve chambers, wastewater treatment plants, flood-prone areas. |
| Large Diameter Pipes / Legacy Network Retrofits | Insertion Type (Insertion Electromagnetic Flowmeter) | Instead of a full-bore spool piece, a measuring probe is inserted to the pipe center via a tapped hole. Procurement and freight costs stay constant regardless of pipe size. Supports hot-tapping (installation under pressure). | Large-diameter water mains (DN300–DN3000), municipal water network retrofits, large industrial cooling systems. |
| Hazardous & Explosive Environments | Explosion-Proof Type (Ex d Flameproof / Ex ia Intrinsic Safety) | Transmitter and sensor feature flameproof (Ex d) or intrinsically safe (Ex ia) enclosures. Certified with ATEX/IECEx to eliminate electrical spark hazards. | Oil & gas facilities, fine chemicals, mining, tank farms/fuel depots, toxic gas processing environments. |
| Partially Filled Pipes / Open Channels / Fluctuating Levels | Partially Filled / Open Channel Type | Integrates high-precision level sensors (ultrasonic/capacitive) with distributed electrode arrays. Maintains accurate flow measurement at 10%–90% liquid fill levels. | Industrial effluent outfalls, partially filled drainage pipes, stormwater discharge channels, gravity-flow canals. |
| Off-Grid Locations / Mobile Pipe Networks | Battery-Powered Type | Powered by an internal 3.6V high-capacity lithium battery (3–8 years battery life). Micro-power design, typically integrated with NB-IoT / 4G / LoRaWAN wireless modules. | Remote agricultural irrigation, district metering areas (DMA) without grid power, smart water leakage monitoring. |
| Hygienic Processes / Frequent CIP/SIP Cleaning | Sanitary / Hygienic Type | Stainless steel housing with hygienic quick-connect fittings (Tri-clamp). Uses FDA-compliant PFA/PTFE liners with zero dead space, resistant to high-temp steam sterilization. | Food & beverage processing, biopharmaceuticals, dairy production lines, high-purity water systems. |
| Extreme Pressure Conditions (Up to 42 MPa) | High-Pressure Type | Engineered with extra-thick forged steel or high-grade alloy flanges. Structure validated via Finite Element Analysis (FEA) for high-pressure resistance. | Oilfield water injection, high-pressure subsea mud drilling/recovery, high-pressure waterjet cutting systems. |
