Overview
The JENSPRIMA innoMag300 Electromagnetic Flowmeter is a high-performance, industrial-grade online flow measurement instrument engineered for precision, reliability, and long-term stability in demanding process environments. Based on Faraday’s Law of Electromagnetic Induction, the innoMag300 measures volumetric flow rate of conductive liquids by detecting the voltage induced across a magnetic field perpendicular to fluid motion. This principle ensures inherent independence from fluid density, temperature, pressure, viscosity, and flow profile—making it uniquely suited for applications where mechanical obstructions, moving parts, or pressure drop are unacceptable. Designed for continuous operation in water treatment plants, chemical processing lines, metallurgical cooling circuits, pulp & paper stock systems, and food-grade transfer pipelines, the innoMag300 delivers consistent metrological performance under variable process conditions, including slurries and mildly abrasive media.
Key Features
- True bidirectional flow measurement with real-time direction detection and integrated sign-sensitive output scaling.
- Zero-pressure-loss design: Full-bore sensor geometry eliminates flow restriction, reducing energy consumption and eliminating risk of clogging in suspended-solid applications.
- Multi-material sensor configuration: Selectable electrode materials (316SS, Hastelloy C, Tantalum, Titanium) and linings (PTFE, natural rubber) enable compatibility with aggressive acids, caustics, saline solutions, potable water, and wastewater.
- High metrological integrity: Certified accuracy of ±0.5% of reading and repeatability of ±0.1%, traceable to national standards via factory calibration reports.
- Flexible installation architecture: Available in integral (S-type) and remote-mounted (L-type) configurations to accommodate space-constrained or hazardous-area installations.
- Robust environmental resilience: IP67-rated housing (aluminum), wide ambient operating range (–20 to +70 °C), and thermal-stable lining options ensure stable operation in outdoor, humid, or thermally fluctuating settings.
Sample Compatibility & Compliance
The innoMag300 is validated for use with liquids having minimum electrical conductivity of 5 µS/cm—covering municipal water, seawater, brines, diluted acids (e.g., HCl, H₂SO₄), alkaline solutions (e.g., NaOH), and non-oily slurries containing up to 10% non-ferrous solids. It complies with IEC 61326-1 (EMC for industrial environments), IEC 60529 (IP67 ingress protection), and meets essential requirements of the EU Electromagnetic Compatibility Directive 2014/30/EU. While not intrinsically safe certified out-of-box, optional ATEX/IECEx-certified versions are available upon request for Zone 1/21 applications. The device supports GLP/GMP-aligned data integrity when paired with compliant SCADA or DCS platforms via MODBUS RTU.
Software & Data Management
The innoMag300 features an embedded firmware platform supporting local parameter configuration via backlit LCD interface with intuitive menu navigation. All configuration changes—including damping time, zero calibration, flow direction logic, and alarm thresholds—are stored in non-volatile memory with timestamped audit logs. Standard MODBUS RTU (RS-485) enables seamless integration into PLC-based control systems (Siemens S7, Rockwell ControlLogix, Schneider Modicon) and supervisory SCADA architectures. Optional HART 7 protocol support allows for advanced diagnostics, sensor health monitoring, and remote commissioning via handheld communicators or asset management software. No proprietary software license is required for basic operation; configuration files are exportable in plain-text CSV format for version control and QA documentation.
Applications
- Drinking water distribution and wastewater influent/effluent metering in municipal utilities.
- Chemical dosing and bulk transfer in ISO-certified pharmaceutical and fine chemical manufacturing.
- Cooling water and descaling solution flow monitoring in steel mill blast furnace and rolling mill circuits.
- Pulp consistency control and white water recirculation in kraft and recycled fiber paper machines.
- Irrigation canal and reservoir discharge measurement in smart agriculture infrastructure.
- Food & beverage CIP (Clean-in-Place) line validation and batch volume reconciliation per FDA 21 CFR Part 11 guidelines.
FAQ
Does the innoMag300 require periodic recalibration?
Yes—while electromagnetic flowmeters exhibit excellent long-term stability, annual verification against a traceable master meter or wet calibration rig is recommended per ISO 9001 and ISO/IEC 17025 quality management frameworks.
Can it measure deionized water or hydrocarbon fluids?
No—deionized water (<5 µS/cm) and non-conductive media (e.g., oils, solvents) fall below the minimum conductivity threshold and cannot be measured reliably.
Is the PTFE lining suitable for steam sterilization (SIP)?
No—PTFE-lined sensors are rated for continuous service up to +150 °C but are not designed for direct exposure to saturated steam; autoclave cycles require alternative construction (e.g., ceramic-lined variants).
What is the maximum allowable system pressure for DN2000 rubber-lined units?
The standard innoMag300 rubber-lined configuration is rated for PN10 (10 bar) at 20 °C; derating applies above +50 °C per EN 1452-2 guidelines.
Does MODBUS implementation support function codes 03, 06, and 16?
Yes—the standard firmware implements full MODBUS RTU register mapping for read-holding-registers (03), preset-single-register (06), and preset-multiple-registers (16), with configurable slave ID and baud rate (up to 115.2 kbps).
