Dwyer IEF-SN-10 Water Flow Sensor — Accurate and Reliable Flow Measurement Solution
The Dwyer IEF-SN-10 water flow sensor is a robust electromagnetic insertion flow measurement device designed to accurately monitor liquid flow in a wide range of industrial and commercial applications. Manufactured by Dwyer and imported and distributed by DLK – DLK Trading Service Company Limited, this sensor provides precise real-time flow measurement for water and other conductive liquids.
Ideal for HVAC systems, building automation (BMS), water treatment, manufacturing, and energy systems, this flow sensor delivers reliable performance with minimal maintenance. Insertion design allows flexible installation without extensive pipe modification. The Dwyer IEF-SN-10 is recognized for its stable output signals and versatile communication options, making it suitable for modern control and monitoring systems.
Operating Principle Explained Clearly and Technically Correct
The Dwyer IEF-SN-10 measures flow based on the electromagnetic principle. When a conductive liquid moves through a magnetic field, it induces a voltage proportional to its velocity. Electrodes located in the sensor detect this induced voltage, which is then converted into a flow reading by the transmitter electronics.
Because it does not rely on mechanical moving parts, the IEF-SN-10 eliminates common issues related to wear and friction seen in mechanical flow meters. This principle ensures accurate measurements regardless of fluid density or viscosity, as long as the liquid is electrically conductive — typically water and water-based solutions used in HVAC, water processing, and industrial circuits.
This technology also contributes to low maintenance needs and high long-term stability. With a direct proportional relationship between flow velocity and output signal, this sensor can interface with controllers using analog, frequency, or digital communication protocols.

The Dwyer IEF-SN-10 provides measurement reliability to guarantee proper feedwater flow and return flow conditions, supporting boiler longevity and efficiency.
Modern energy systems often rely on digital control loops where precise input data is critical. With selectable outputs including analog and digital communication, the Dwyer sensor fits seamlessly into these environments, ensuring data integrity and system responsiveness.
Benefits of Using the Dwyer IEF-SN-10 Sensor
The Dwyer IEF-SN-10 offers several technical and operational advantages:
High Accuracy: With a standard accuracy of ±1 % full scale, and optional high accuracy configurations, it delivers precise flow measurement vital for control systems and performance reporting.
No Mechanical Wear: Because the measurement is electromagnetic rather than mechanical, there are no moving parts to wear down. This results in reduced maintenance frequency and longer service life.
Flexible Signal Outputs: Supports analog (4–20 mA and 0–10 V), pulse/frequency, and digital protocols such as BACnet MS/TP and Modbus RTU via RS-485, enabling integration with diverse control architectures.
Insertion Design: Installation is simplified with insertion mounting, minimizing the need for pipe cutting or specialized fittings. This is particularly advantageous for retrofits and maintenance scenarios.
Broad Compatibility: Ideal for conductive liquids like treated water, chilled and hot water circuits, makeup water, and wastewater streams.
