Rosemount 8705 flanged magnetic flow meter sensors are fabricated from stainless and carbon steel, and welded to provide a hermetic seal that protects against moisture and other contaminants. The sealed housing in the 8705 flanged flow tube ensures maximum flow tube sensor reliability by protecting all internal components and wiring from the most hostile environments.

The Rosemount 8705's obstructionless design features no moving parts, which minimizes maintenance and repair. The sensor features a removable and replaceable terminal block that enables easy repair in the field without the need to replace the entire meter. The 8705 also offers optional secondary containment compartments that surround electrodes and capture any potential process fluid leakage. An optional lining protector is also available to guard against installation damage and leading-edge wear.

Rosemount megameter systems use pulsed DC technology that provides continuous automatic zeroing to compensate for variations in the process environment. Process liquid must have a conductivity of 5 microsiemens/cm (5 micromhos/cm) or greater.

Rosemount 8700 series flow tubes are interchangeable with both the 8712D and 8732 flow transmitters. System accuracy is maintained regardless of line size or optional features. Each Rosemount 8705 flanged flow tube nameplate has a sixteen-digit calibration number that can be entered into a transmitter through the Local Operator interface or the HART Communicator, depending on model.
