The Rosemount 8732E field-mounted electromagnetic flowmeter transmitter is the best way to measure flow in industries where accuracy is important. This detailed guide talks about how this high-tech gadget works perfectly and consistently in tough situations in places like oil and chemical processing, water treatment, and power plants. Engineers and buying workers can make smart choices about where to invest in flow measurement equipment when they know what it can do.
Faraday's Law of Electromagnetic Induction tells us how electromagnetic flowmeters work. A voltage is created across an electrical liquid when it moves through a magnetic field created by the flowmeter coils. This generated voltage is directly related to how fast the liquid is moving on average. The flow line stays completely clear because the measurement doesn't need any moving parts or other elements that get in the way. This basic idea makes it possible to measure flow very accurately and reliably, even in tough process conditions where mechanical devices could break down due to wear or fouling.
This technology works especially well with acidic chemicals, rough slurries, and wastewater that hasn't been cleaned. Electromagnetic devices don't have any parts that stick out and break like mechanical flowmeters do, which depend on paddles, rotors, or spinning parts. So, these flowmeters keep their very high level of measurement accuracy over long periods of time without needing to be recalibrated or parts replaced often. Also, because there are no internal barriers, there is no pressure drop across the meter and no chance of it getting clogged, even when reading fluids that contain solids or fibers in them.
It is the job of field-mounted emitters to process electrical data right at the measurement point, next to the flow sensor. This limited signal processing setup makes signal loss much less likely than it would be over long wire runs. It also lessens the effect of electromagnetic radiation from motors, pumps, and variable frequency drives that are close by. Field-mounted emitters improve signal integrity, measurement stability, and reaction speed compared to systems where analog signals have to travel long distances to electronics boxes or control rooms that are far away. This is because they turn and boost raw sensor data on-site.
The total measurement stability of electromagnetic flowmeters is greatly improved by modern digital signal processing (DSP) technology. Modern receivers have advanced algorithms that can cleverly filter out process-generated electrical noise, like that caused by slurry flow, chemical reactions, or random currents, while keeping the real signal caused by flow. This feature is very useful in places with a lot of electrical noise, like steel mills, mines, and water treatment plants that use variable frequency drives. In these kinds of difficult situations, analog systems often have trouble, giving inconsistent numbers or needing to be adjusted all the time. Digital systems, on the other hand, always give accurate flow data.
The dual-compartment housing represents intelligent engineering. One chamber contains electronic components while the other houses wiring terminals. This separation protects sensitive circuits from moisture and environmental contaminants that enter through conduit connections.
All-welded construction creates a hermetic seal around critical components. Unlike gasketed designs, welded housings eliminate potential leak paths. This robust protection extends equipment lifespan in harsh outdoor installations and chemically aggressive atmospheres.

Bidirectional flow measurement from 0.04 to 39 ft/s handles complex process requirements. Chemical batch operations often involve flow reversals during charging and discharging cycles. Accurate measurement in both directions supports precise material balance calculations.
Empty pipe detection with adjustable sensitivity prevents erroneous flow readings. When the liquid level drops below the electrode height, the system recognizes this condition. Configurable thresholds accommodate different pipe orientations and process characteristics.
Grounding verification diagnostics identify installation issues before they affect measurement. Proper grounding ensures accurate signal reference and protects against electrical noise. Automated verification during commissioning accelerates startup procedures.
Process noise analysis with selectable coil drive frequencies optimizes performance. Facilities with variable frequency drives or welding equipment generate electromagnetic interference. Adjusting the excitation frequency moves the measurement signal away from interference sources.
