Magmeter Diagnostics

Rosemount diagnostics reduce cost & improve output by enabling new practices
Rosemount Magnetic Flowmeters provide device diagnostics that detect and warn of abnormal situations throughout the life of the meter - from installation to maintenance and meter verification. With Rosemount Magnetic Flowmeter diagnostics enabled, plant availability and throughput can be improved, and costs through simplified installation, maintenance and troubleshooting can be reduced.

Magnetic Flowmeter Sizing

Selecting the appropriate sensor size is an important step when considering a magnetic flowmeter. The physical properties of the process fluid, as well as the fluid velocity should be considered. It may be necessary to select a flow sensor that is larger or smaller than the adjacent piping to ensure the fluid velocity is in the recommended flow range for the application.
Operation outside these guidelines may also give acceptable performance.
Sizing guidelinesTable 3:
Application Velocity range (ft/s) Velocity range (m/s)
Normal Service 0–39 0–12
Preferred Service 2–20 0.6–6.1
Note
Operation outside these guidelines may also give acceptable performance.
To convert flow rate to velocity, use the appropriate factor lis­ted in Table 4 and the following equation:

Upstream and downstream piping

To ensure specified accuracy over widely varying process conditions, install the sensor with a minimum of five straight pipe diameters upstream and two pipe diameters downstream from the electrode plane.

Upstream and downstream straight pipe diametersFigure 1:
A. Five pipe diameters (upstream) B. Two pipe diameters (downstream) C. Flow direction
Installations with reduced upstream and downstream straight runs are possible. In reduced straight run installations, the meter may not meet absolute accuracy specifications. Reported flow rates will still be highly repeatable.

Sensor grounding

A reliable ground path is required between the sensor and the process fluid. Optional grounding rings or process reference electrodes are available with 8750W Sensors to ensure proper grounding. See Table 5 and Table 6.

Ordering flowmeter equipment

Ordering procedure
To order, select the desired sensor and/or transmitter by specifying model codes from the ordering table.
For remote transmitter applications, note the cable specification requirements.
Standard configuration
Unless the Configuration Data Sheet is completed, the transmitter will be shipped as follows:
Engineering units: ft/sec
4mA: 0
20mA: 30
Sensor size: 3-in.
Empty pipe: On
Sensor calibration number: 1000005010000000
Integrally mounted transmitters are factory configured with the paired sensor size and appropriate calibration number.
Custom configuration (option code C1)
If Option Code C1 is ordered, the Configuration Data Sheet (CDS) must be submitted at the time of order.
Standard tagging
Instrument tags for the transmitter and sensors are as follows:
316SST laser etched label, permanently attached
Main label - Tag name: 1 line 21characters
Additional 316SST 'wire-on' tag available: 5 lines, 17 characters per line (6mm height)
Interconnecting cable
Interconnecting cables are required to connect a remote mount transmitter to the sensor. When ordering cable, review the hazardous area approval requirements and the installation location requirements for proper cable selection.
Cables can be ordered as individual component cables or a combination coil drive/electrode cable.
Cables can be ordered as part of the transmitter model number or as a spare parts kit. Integrally mounted transmitters are
factory wired and do not require additional interconnecting cables.
Individual component cables require equal lengths of coil drive cable and electrode cable and should be limited to less than 500 feet (152 m). Consult Technical Support for lengths between 500-1000 feet (152-304 m).
Combination coil drive/electrode cable is only available for Ordinary Locations and should be limited to less than 330 feet (100 m).
