Rosemount Magnetic Flowmeter System
8750W for Water/Wastewater & Utility Applications
The operating principle of the magnetic flowmeter system is based upon Faraday’s Law of electromagnetic induction, which states that a voltage will be induced in a conductor moving through a magnetic field.
Faraday’s Law: E=kBDV
The magnitude of the induced voltage E is directly proportional to the velocity of the conductor V, conductor width D, and the strength of the magnetic field B. The figure below of a Model 8750W sensor illustrates the relationship between the physical components of the magnetic flowmeter and Faraday’s Law.
Magnetic field coils placed on opposite sides of the pipe generate a magnetic field. As the conductive process liquid moves through the field with average velocity V , electrodes sense the induced voltage. The width of the conductor is represented by the distance between electrodes. An insulating liner prevents the signal from shorting to the pipe wall.
The only variable in this application of Faraday’s Law is the velocity of the conductive liquid V because field strength is controlled constant and electrode spacing is fixed. Therefore, the output voltage E is directly proportional to liquid velocity, resulting in the inherently linear output of a Rosemount Magnetic Flowmeter.
Rosemount Magmeters provide device diagnostics that informs the user of abnormal situations throughout the life of the meter - from Installation to Maintenance and Meter Verification.
With Rosemount Magmeter diagnostics enabled, users can change their practices to improve plant availability and output, and reduce costs through simplified installation, maintenance and troubleshooting.
Rosemount Magmeter Diagnostics can be accessed through the Local Operator Interface (LOI), a HART Field Communicator, or AMS Device Manager.
Access Diagnostics through the LOI for quicker installation, maintenance, and meter verification
Rosemount Magmeter Diagnostics are available through the LOI to make maintenance of every magmeter easier.
Access Diagnostics through AMS™^ Suite: Intelligent Device Manager for the Ultimate Value
The value of the Diagnostics increases significantly when AMS is used. AMS provides a simplified screen flow and procedures for how to respond to the Diagnostic messages.

SMART Meter Verification
Verifying magmeter calibration has traditionally required the flowmeter to be removed from the line and re-calibrated in a flow lab or with a prover. More recently, verification using a field calibrator has become a popular solution, but it still requires extra equipment and is a time consuming process.
Now the Rosemount SMART Meter Verification diagnostic allows users to verify the flowmeter without additional equipment. Initiated directly through the meter Local Operator Interface (LOI), a HART Field Communicator or AMS™^ Suite: Intelligent Device Manager, SMART Meter Verification verifies both the transmitter and sensor calibration. The displayed results can be used to fill out the verification form, or simply print the results when using AMS Device Manager.
SMART Meter Verification delivers a fast and cost-effective approach to meter verification with no additional equipment. This diagnostic is one of the optional advanced diagnostic options (DA2) in the Rosemount 8750W Magnetic Flowmeter model number.
High process noise detection
Loop control in many chemical and slurry applications can be difficult due to “noisy” output from the flowmeter. The historic practice was to add damping to the flowmeter’s output to stabilize the flow signal. This adds deadtime to the control loop resulting in additional process variability that drives up operating costs.
Only Rosemount 8750W Magmeters have a comprehensive solution to optimize installed performance and signal stability in even the noisiest applications, without additional damping. The high process noise diagnostic alerts you when variability is caused by process noise and not actual flow variation. This allows you to adjust to a higher coil drive frequency to stabilize the output without adding damping. By taking advantage of the high process noise diagnostic and scalable coil drive capability you improve process control, increase product quality and reduce scrap. This diagnostic is one of the optional advanced diagnostic options (DA1) in the Rosemount 8750W Magnetic Flowmeter model number.
Grounding/wiring fault detection
Rosemount technology provides a grounding and wiring fault detection diagnostic to dramatically reduce the time and cost of installing magmeters. One of the most common installation issues with magmeters is the lack of a proper ground. Without a proper ground, the meter will not read flow correctly. By continually monitoring the line noise voltage across the frequency spectrum, Rosemount technology can detect and alert you immediately if the meter wiring or grounding needs to be fixed. This saves commissioning time, reduces installation costs, and can help prevent inaccurate measurements. This diagnostic is one of the optional advanced diagnostic options (DA1) in the Rosemount 8750W Magnetic Flowmeter model number.

Security lockout
Security lockout switch on the electronics board can be set to deactivate all LOI and HART-based communicator functions to protect configuration variables from unwanted or accidental change.
Field Mount LOI lockout All optical switches on the display can be locked locally from the display layout configuration screen by holding the upper right optical switch for 10 seconds. The display can be reactivated holding the same switch for 10 seconds. Submergence protection (flanged sensor only) - R05/R10/R15/R20/R25/R30 Options Continuous submergence up to 30 ft. (10 m) requires conduit entries of the sensor remote junction box to be properly sealed to prevent water ingress. This requires the user to install sealed IP68 approved cable glands, conduit connections, or conduit plugs. For more details on proper installation techniques for an IP68 / submersible application, reference Rosemount Technical Document 00840-0100-4750 available on www.Rosemount.com. Option Codes R05, R10, R15, R20, R25, and R30 provide a pre-wired potted and sealed junction box to prevent the ingress of water. These options still require the use of sealed conduits to meet IP68 protection requirements. Example of a protection category: Identity letters - IP First identity number - 6 (1) Second identity number - 8 (2)
(1) Protection against the entry of dust (dust-proof). Complete contact prevention. (2) The enclosure is suitable for constant submersion in water under given conditions which are determined by the manufacturer (submersion).
Electrical connections
Two 1 / 2 –14 NPT connections with number 8 screw terminals are provided in the terminal enclosure for electrical wiring.
Process reference (grounding) electrode
A process reference electrode is installed similarly to the measurement electrodes through the lining of the sensor. It will be made of the same material as the measurement electrodes.
Grounding rings - (optional)
Grounding rings are installed between the flange and the sensor face on both ends of the sensor. Single ground rings can be installed on either end of the sensor. They have an I.D. slightly larger than the sensor I.D. and an external tab to attach ground wiring. Grounding rings are available in 316L SST and Nickel Alloy 276 (UNS N10276).
