What is a Full Bore Inline Electromagnetic Flow Meter?
A Full Bore (Inline) Electromagnetic Flow Meter — often referred to as an inline magmeter — is a state-of-the-art flow measurement instrument designed for accurate, reliable and maintenance-free measurement of conductive liquids in closed pipelines. Unlike mechanical or obstruction-type flow meters, a full bore inline electromagnetic flow meter allows the fluid to pass unimpeded through a full-diameter pipe, ensuring zero or negligible pressure drop, minimal flow disturbance, and consistent long-term performance.
As a reputed manufacturer & supplier in Pune, India, Saitechflow specializes in engineering and supplying high-quality full bore electromagnetic flow meters to industries across India — from municipal water supply and wastewater treatment to chemical, food & beverage, and general industrial processes.
Whether you are designing a new plant, retrofitting an existing pipeline, or automating fluid flow measurement — our inline magmeters provide a robust solution tailored to Indian industrial conditions.

Why Choose Full Bore Inline Magmeters over Other Flow Meters?
Full bore inline electromagnetic flow meters offer several significant advantages compared to mechanical or partial-bore meters. Some of the key benefits:
- No moving parts: The meter has no internal moving components. This means minimal wear and tear, no risk of blockage by suspended solids or particles, and drastically reduced maintenance frequency.
- Unobstructed, full-bore flow path: Because the internal bore diameter is the same as the pipeline, there’s virtually no pressure drop. This is especially beneficial in long-distance pipelines or high-flow applications where maintaining pressure and flow efficiency is critical.
- High accuracy & reliability: Inline electromagnetic meters provide excellent measurement fidelity (often ±0.5% or better), making them ideal where precise flow data is required — such as water billing, chemical dosing, process control, and compliance monitoring.
- Insensitive to fluid properties: Because the measurement principle depends on conductivity rather than mechanical movement, the flow reading remains stable regardless of fluid density, viscosity, temperature, or pressure (provided the fluid is electrically conductive).
- Suitable for challenging liquids: They perform reliably even with slurries, wastewater, corrosive or abrasive liquids, sludge, chemicals — where traditional flow meters may fail or require frequent maintenance.
- Bidirectional flow capability: Many electromagnetic meters can detect and measure flow in both forward and reverse directions — useful in systems with variable flow paths or recirculation.
- Digital-ready & automation-friendly: Modern inline magmeters often support 4–20 mA, pulse, HART, RS-485 / Modbus outputs — enabling seamless integration with SCADA, PLC, or telemetry systems.
These benefits make full bore inline magmeters one of the most versatile and future-proof flow measurement solutions for industrial, commercial, and municipal applications.
How Inline Electromagnetic Flow Meters Work — Principle & Construction
The working principle of an electromagnetic flow meter is based on Faraday’s Law of Electromagnetic Induction: when a conducting fluid flows through a magnetic field perpendicular to the direction of flow, it induces a voltage proportional to the fluid’s velocity.
🔧 Basic Construction:
- A non-magnetic pipe or liner (rubber, PTFE, or other insulating material) forms the flow tube.
- Electromagnetic coils around the tube generate a magnetic field across the entire cross-sectional area.
- Electrodes flush-mounted opposite each other on the inner wall detect the induced voltage as the conductive fluid flows.
- An electronic converter/transmitter processes the voltage signal, converts it into flow rate (volume/time), and outputs standardized signals (4–20 mA, pulse, RS-485 / Modbus, etc.).
Because the entire cross-section of fluid is magnetized, and flow is measured volumetrically, the meter remains accurate whether the fluid is clean water, wastewater, slurry, or a chemical mixture.
Important Requirement: the fluid must be electrically conductive (typically above a minimum conductivity threshold, often ~ 5 µS/cm). Non-conductive fluids like pure oils, gases, or steam cannot be measured using electromagnetic flow meters.

To ensure accurate and reliable flow measurement over the lifetime of the meter, proper installation is crucial. Here are Saitechflow’s recommended guidelines:
- Ensure full-pipe flow: The pipeline should always be completely filled. Partial flow or air bubbles cause significant measurement errors.
- Maintain straight pipe runs: Provide at least 5 × D upstream and 3 × D downstream straight lengths (D = pipe internal diameter) to avoid swirl or flow distortion at the sensor.
- Proper grounding: Ensure good electrical grounding and avoid nearby sources of electromagnetic interference (motors, heavy electrical equipment).
- Orientation: Install the meter so that there are no air pockets near electrodes — horizontal or vertical installation must ensure full pipe, with electrodes at correct orientation.
- Avoid vibration: If pipeline is subject to vibration, use proper supports or remote-mounted transmitter options.
- Routine maintenance & calibration: Though inline magmeters are low maintenance, periodic inspection and verification (especially for abrasive or chemical fluids) ensures consistent accuracy over years.
Saitechflow provides detailed installation guidelines, commissioning checklists, and on-site support to help customers get accurate readings from day one.
Frequently Asked Questions (FAQ)
Q: Can electromagnetic flow meters measure non-conductive liquids like oils or gases?
A: No — inline electromagnetic flow meters require the fluid to be electrically conductive (usually > ~5 µS/cm). Non-conductive liquids, pure hydrocarbons, oils, or gases cannot be measured reliably.
Q: Will suspended solids, sludge or slurry affect measurement accuracy?
A: Not significantly. Because there are no moving parts and the flow path is unobstructed, even slurries or wastewater with particulates can be measured accurately — provided the fluid maintains sufficient conductivity.
Q: What size ranges are available?
A: Saitechflow offers inline magmeters from small bore (e.g. DN 15 / ½″) to large industrial pipelines (DN 600 and beyond), plus custom sizes on request.
Q: Can the meter output integrate with PLC / SCADA systems?
A: Yes — our inline magnetic flow meters support standard industrial outputs: 4–20 mA, pulse, RS-485 / Modbus, HART, and more. Remote or compact transmitters are available.
Q: What about maintenance?
A: Since there are no moving components, maintenance is minimal — periodic inspection of electrodes / lining depending on application; calibration checks as per standard practice.

Working Principle
The High-Temperature / High-Pressure Electromagnetic Flow Meter operates on the simple yet powerful Faraday’s Law of Electromagnetic Induction.
When a conductive fluid passes through a magnetic field generated by coils in the flow tube, it induces a voltage proportional to the fluid velocity.

This contactless measurement ensures:
- No pressure drop
