Rosemount 8707 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 Rosemount 8707 is available in sizes ranging from 3 to 36 inches. The sealed housing ensures maximum flowtube sensor reliability by protecting all internal components and wiring from the most hostile environments.

Rosemount magmeter 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 50 microsiemens/cm (50 micromhos/cm) when used with 8712H, or 5 microsiemens/cm when used with other transmitters.

Rosemount 8707 sensors are interchangeable with 8732, 8712, and 8712H high-signal transmitters. System accuracy is maintained regardless of line size or optional features. Each sensor nameplate has a sixteen-digit calibration number that can be entered into a transmitter through the Local Operator Interface (LOI) or the HART Communicator.

Instrumart is an IDWR-approved flow meter vendor

The Rosemount 8700 series flanged flowtube sensor is an IDWR-certified flow meter as outlined in the Idaho Department of Water Resources state order requiring flow meters to be installed by water users that divert water in regulated areas from both ground and surface water sources. This flow meter was tested by the staff at Utah State's NIST traceable lab and passed all requirements set by the IDWR and Idaho Department of Agriculture. If you have any questions about this flow meter or what IDWR-approved flow meter best fits your application, please ask one of our helpful engineers. 1-800-884-4967.
