Dwyer IEF-SN-10 Insertion Electromagnetic Flow Transmitter – High Accuracy ±0.5%, Integrated BACnet/Modbus
When solving Energy Management problems or monitoring liquid flow in large-diameter pipelines (from 4 to 36 inches), traditional mechanical flow meters expose critical drawbacks: continuous pressure loss, mechanical wear, and high replacement costs. The Dwyer IEF-SN-10 Insertion Electromagnetic Flow Transmitter solves these challenges, offering non-invasive electromagnetic measuring technology with zero head loss and an impressive accuracy of up to ±0.5%.

1. Groundbreaking Technical Features of the Dwyer IEF-SN-10
The Dwyer IEF-SN-10 (Series IEF Insertion Electromagnetic Flow Transmitter) represents the smart generation of integrated sensors for modern smart buildings and industrial facilities:
-
Insertion Magmeter Technology: The transmitter inserts directly into the pipe via a hot-tap isolation valve without reducing pipe cross-sections, eliminating pressure drop completely.
-
High Accuracy Performance (±0.5%): High-accuracy calibration ensures precise measurement of instantaneous flow rate and totalized flow for chilled water, hot water, or Glycol mixtures (0-100%).
-
Intuitive Graphic LCD Display: Features a built-in multi-parameter graphic LCD display, enabling field engineers to set pipe sizes, flow ranges, and engineering units directly via user-friendly buttons.
-
Dual Modbus RTU & BACnet MS/TP Communications: Built-in RS-485 serial communication transmits real-time flow rate, temperature, and totalized volume data directly to BMS/SCADA systems without requiring external gateways.

3. Application Benefits in HVAC Energy Management
-
Chiller Plant BTU Metering: Combines IEF-SN-10 flow signals with supply/return temperature sensor pairs to calculate real-time cooling energy consumption (BTU / Tons of Refrigeration).
-
Hot-Tap Installation: Allows mounting and servicing under full pipe line pressure without shutting down or draining the system.
-
Automatic Glycol Compensation: Configurable for Glycol concentration from 0 to 100%, delivering highly accurate flow calculations in sub-zero secondary cooling loops.
⚠️ Field Installation Pro-Tip: Insertion magmeter accuracy heavily depends on insertion depth alignment and straight pipe runs. Ensure a minimum straight run of 10 pipe diameters upstream and 5 pipe diameters downstream to prevent flow swirl distortion.
