S2MMM843-SS1030

The Yokogawa S2MMM843-SS1030 is a highly specialized Magnetic Flowmeter Sensor (Primary Element) from the ADMAG AXF Series. It is not a complete flowmeter; it is the part that is directly installed in the pipe and contains the flow tube, liner, electrodes, and coils that generate the magnetic field.

Parameter Specification Details / Notes
Model Number S2MMM843-SS1030 S2MMM843: Base model code for the sensor size/type.
-SS1030: Material code.
Product Line Yokogawa ADMAG AXF Series
Device Type Magnetic Flowmeter Sensor (Primary Element) Requires a separate converter.
Nominal Pipe Size 3 inch (80 mm) Derived from the model code 843 (often 80mm/3" nominal).
Flange Standard ANSI/ASME Class rating (e.g., 150lb, 300lb) must be confirmed from order documents.
Meter Body Material Stainless Steel (as per SS code) Typically ASTM CF8M (equivalent to 316SS).
Liner Material PTFE (Polytetrafluoroethylene) (as per 10 code) Excellent chemical resistance. Suitable for temperatures up to approx. 180°C (356°F).
Electrode Material Hastelloy C-22 (as per 30 code) Excellent resistance to pitting, crevice corrosion, and oxidizing acids.
Grounding Electrode Usually standard (material same as main electrodes).
Flow Velocity Range 0 to 10 m/s (33 ft/s) (typical for mag meters) Minimum conductivity required: ~5 μS/cm.
Accuracy ±0.35% of rate or better (when paired with a compatible AXF converter)
Ambient Temperature -40 to +60 °C (-40 to +140 °F) (for sensor)
Process Temperature -40 to +180 °C (-40 to +356 °F) Limited by the PTFE liner.
Pressure Rating Varies by flange class (e.g., ANSI 150#: 20 bar / 290 psi at 100°C) Must be confirmed from specific order documents.
Protection Rating Typically IP67 / NEMA 4X (for sensor) Suitable for harsh environments and wash-downs.
Connection to Converter Integral cable or remote connection via junction box.
