Key parameters
Measuring range
Wafer (flangeless) mag sensor; 8711-M/L line sizes 1½–8 in (40–200 mm); legacy R/U also 0.15/0.30/½/1 in; upper range limit 39 ft/s (12 m/s)
Accuracy
Platform standard reference accuracy 0.25% of rate; optional high accuracy 0.15% of rate (matched sensor/transmitter D1)
Output
Sensor only — pairs with Rosemount 8732/8712 transmitters (4–20 mA HART, FF, Modbus, EtherNet/IP per transmitter)
Supply
Sensor powered/driven by paired transmitter (see 8700M transmitter power tables)
Process connection
Wafer/flangeless between flanges; alignment spacers included; mating flange ratings ASME 150/300, EN PN10/16/25/40, etc.
Wetted parts
Liners PTFE/PFA/ETFE; electrodes 316L SST, Nickel Alloy 276, Tantalum, Pt/Ir, Titanium
Fits flangeless magmeter installs where you need a Rosemount 8711 wafer sensor in 1½–8 in (40–200 mm) line sizes with 0.25% of rate standard accuracy (0.15% optional) paired to 8732/8712 transmitters.
Key advantages
- Sizes — 1½–8 in (40–200 mm); legacy small sizes also
- URL — Upper range to 39 ft/s (12 m/s)
- Accuracy — 0.25% of rate standard; 0.15% optional matched
- Form — Wafer / flangeless mag sensor
- Transmitters — Pairs with Rosemount 8732/8712 (HART/FF/Modbus/EIP)
Typical applications
- Compact magmeter skids.
- Conductive liquid flow without meter flanges.
- Retrofit wafer mag sensors.
Selection guide
