Rosemount 8700 Magnetic Flow Meter

Overview

The Rosemount 8700 Magnetic Flow Meter Series is a complete magnetic flowmeter system consisting of a flanged, wafer, or sanitary sensor paired with a Rosemount 8712 or 8732 transmitter, engineered for reliable liquid flow measurement across a broad range of process conditions. Rosemount 8700 series flowtubes are fabricated from stainless and carbon steel, welded to provide a hermetic seal that protects internal components and wiring against moisture and other contaminants.

As an authorized supplier of Emerson instrumentation, Seven Star LLC proudly offers the Rosemount 8700 Series to water and wastewater treatment plants, chemical processing facilities, and industrial water management operations across the Sultanate of Oman, Muscat, and the wider GCC. Available in sizes from 3 to 36 inches, the 8700 Series scales from small process lines to large municipal water mains.

Measurement Principle

The Rosemount 8700 uses pulsed DC coil drive technology, providing continuous automatic zeroing to compensate for variations in the process environment. This approach delivers 0.5% standard accuracy, with a 0.25% high-accuracy option available for applications demanding tighter measurement tolerances, all while maintaining an obstructionless flow path with no moving parts to wear or clog.

Sensor and transmitter combinations are interchangeable within the 8700 platform (with 8712 and 8732 transmitters), and system accuracy is maintained regardless of line size or optional features. Each flowtube sensor carries a sixteen-digit calibration number that can be entered into the transmitter through the Local Operator Interface (LOI) or a HART Communicator, simplifying sensor replacement and recalibration in the field.

Engineering Design of the Rosemount 8700

The Rosemount 8700 sealed housing carries an IP68 rating, ensuring maximum flowtube sensor reliability by protecting all internal components and wiring from the most hostile environments, including continuous submergence applications. Advanced diagnostic suites are available covering reverse flow detection, high process noise monitoring, grounding and wiring fault detection, and smart meter verification—giving plant engineers unparalleled process management visibility.

Transmitters in the 8700 platform can be integrally mounted directly on the sensor or remotely mounted for installations where local space is constrained or ambient conditions require the electronics to be located away from the process. The Rosemount 8712 HART transmitter includes Device Diagnostics with Smart Meter Verification, giving operators confidence in ongoing meter performance without physically removing the flowtube for inspection.
