These characteristics make the SITRANS FM MAG 6000 transmitter a solid choice wherever reliable and repeatable volumetric flow measurement is required, from water distribution networks to process industry batching lines.​

Functional features and exploitation in industrial systems

The MAG 6000 platform offers several core functions that go beyond basic flow indication.​

• Instantaneous flow rate and totalizers: Two independent totalizers allow separate registration of forward and reverse flow or batching totals.​
• Wide turndown and low‑flow cut‑off: Digital signal processing and high‑resolution measurement provide stable readings at both very low and very high velocities.​
• Batch control and limit switching: Integrated batch controller with configurable relay outputs can start, stop, and fine‑tune dosing operations without an external PLC in smaller systems.​
• Diagnostic and self‑verification: Built‑in self‑diagnostics and optional verification functions help operators detect coil faults, empty pipe alarms, configuration errors, and sensor problems early.​

In daily exploitation this means a plant can use a single MAG 6000 transmitter as a measurement, supervisory, and basic control element, saving cabinet space and engineering time while maintaining metering‑class accuracy.​

Comparison with other MAG transmitters and typical competitors

To clarify the position of the MAG 6000, the table compares it with the Siemens MAG 5000 transmitter and a generic compact electromagnetic flow transmitter of similar class.​

Feature	SITRANS FM MAG 6000	Siemens MAG 5000	Typical compact magmeter transmitter
Accuracy	±0.2% of flow rate ±1 mm/s​	±0.4% of flow rate ±1 mm/s​	Often ±0.5–1.0% of flow rate
Power supply options	12–24 V AC/DC or 115–230 V AC 50/60 Hz​	12–24 V AC/DC or 115–230 V AC​	Usually one fixed range (e.g. 100–240 V AC)
Enclosure rating	IP67 / NEMA 4X/6 and IP20 (19’’ insert)​	IP67 / NEMA 6 and IP20​	Often IP65 only
Functions	Batch control, advanced diagnostics, plug‑in communication modules​	Basic flow and totalizers, limited advanced functions​	Basic flow indication and 4–20 mA output
Typical application	Custody‑transfer, demanding industrial processes, water utilities​	Standard industrial water and wastewater​	Simple plant utilities and OEM skids

Compared with the MAG 5000, the MAG 6000 offers tighter accuracy, extended communication options, and integrated batch functionality, making it more suitable for high‑value products and billing applications.​
Against a typical compact magmeter, the MAG 6000 stands out with its rugged IP67 housing, richer diagnostics, and modular communications, which are important in large plants seeking long‑term reliability and easy integration.​

Value comparison with alternative technologies

When deciding between the SITRANS FM MAG 6000 and other flow measurement technologies, engineers usually compare performance, installation constraints, and lifecycle cost.​

Criterion	MAG 6000 + electromagnetic sensor	Turbine flowmeter	Differential‑pressure (orifice) system
Moving parts	None, fully static measurement​	Rotating turbine prone to wear	No moving parts but involves impulse lines
Accuracy and stability	High accuracy (±0.2%) with very low drift​	Good initially, but degrades with wear	Moderate; affected by installation and density changes
Sensitivity to fluid properties	Largely independent of pressure, temperature, and viscosity if fluid is conductive​	Sensitive to viscosity, density, and contamination	Requires stable density and Reynolds number
Maintenance	Minimal; occasional cleaning and verification​	Regular bearing replacement and cleaning	Periodic transmitter recalibration and impulse line purging
Typical media	Water, wastewater, slurries, chemicals with sufficient conductivity​	Clean liquids	Gases, steam, some liquids

Because the electromagnetic principle does not introduce obstruction or moving parts, the MAG 6000 solution usually offers lower total cost of ownership in water and wastewater plants compared with turbine or orifice systems, especially where solids or scaling are present.​
