SYSTEM DESCRIPTION The Rosemount
®
8700 Series Magnetic Flowmeter System consists of a
sensor and transmitter, and measures volumetric flow rate by detecting the
velocity of a conductive liquid that passes through a magnetic field.
There are four Rosemount magnetic flowmeter sensors:
• Flanged Rosemount 8705
• Flanged High-Signal Rosemount 8707
• Wafer-Style Rosemount 8711
• Sanitary Rosemount 8721
There are two Rosemount magnetic flowmeter transmitters:
• Rosemount 8712
• Rosemount 8732
The sensor is installed in-line with process piping — either vertically or
horizontally. Coils located on opposite sides of the sensor create a magnetic
field. Electrodes located perpendicular to the coils make contact with the
process fluid. A conductive liquid moving through the magnetic field
generates a voltage at the two electrodes that is proportional to the flow
velocity.
The transmitter drives the coils to generate a magnetic field, and electronically
conditions the voltage detected by the electrodes to provide a flow signal. The
transmitter can be integrally or remotely mounted from the sensor.
This manual is designed to assist in the installation and operation of the
Rosemount 8732 Magnetic Flowmeter Transmitter and the Rosemount 8700
Series Magnetic Flowmeter Sensors.
