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.
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.

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.
