When it comes to dependability, the Rosemount 8705 flange-type electromagnetic flowmeter sensor really shines. It works perfectly even in the toughest industrial settings. The hermetic seal created by the fully welded construction of this sensor keeps wetness, dirt, and harsh weather conditions from getting to the internal parts. The sealed case design keeps harmful substances out, which guarantees stable operation for a long time. This magnetic flowmeter doesn't need much upkeep because it doesn't have any moving parts, and its terminal blocks can be serviced in the field. This makes it a reliable choice for important process readings in the petrochemical, power generation, and water treatment industries.
Any industrial sensor that needs to be reliable needs to be built with strong engineering. The Rosemount 8705 does just that by making smart design choices and using only the best materials.
The all-welded structure is a big step forward in making flowmeters last longer. Unlike other sensors that use gaskets or mechanical seals, the body of this electromagnetic flow sensor is totally sealed, so it doesn't let moisture or dirt in. This airtight design is especially useful for placements outside or in damp places where regular meters often fail. The body is made of welded stainless and carbon steel, so it can survive high and low temperatures while still measuring accurately. This means that your process data will always be correct, no matter what the outside conditions are like.
The choice of material has a direct effect on how long a sensor lasts. The 8705 has a number of covering choices, such as PTFE, PFA, and polyurethane rubber. Each is designed to be compatible with a certain group of chemicals. For general use, electrodes are made of 316L stainless steel. For very acidic conditions, they are made of platinum and tantalum. This flexibility lets you exactly match the sensor configuration to the properties of your process fluid. This prevents premature wear and increases working life far beyond that of standard flowmeters.
This flanged electromagnetic flowmeter uses pulsed DC technology that continuously zeros the device, adjusting for changes in process conditions without any user input. Other measurement methods can lose accuracy over time, but this one doesn't because it doesn't let the signal move. Because there are no obstructions in the flow line, there is no pressure drop across the meter and no wear from moving parts. This directly leads to lower upkeep costs and better process efficiency.
Even the most reliable monitor (Rosemount 8705 Flange type electromagnetic flowmeter sensor) needs to be set up correctly so that it works at its best for its whole life. Knowing about these practical aspects will help you get the most out of your investment and keep downtime to a minimum.
The changeable and replacement terminal block is a useful new feature that has a big effect on the total cost of ownership. When there are problems with the wiring or connections, repair workers can change the terminal assembly without having to shut down the process or take the meter off. This plan gets rid of the need to replace the whole unit, which saves a lot of money on tools and time spent making things. The terminal section stays separate from the sealed sensor body, making it easy to get to while keeping the important measurement parts hermetically sealed.
When you attach the flanges correctly, you avoid mechanical stress that can affect the accuracy of your measurements over time. The sensor works with a number of different flange standards, such as ASME B16.5 up to Class 2500, DIN PN rates, and AWWA specs, so it can be used with existing pipe systems. Optional case shields keep the installation from getting damaged while it's being handled and keep the cutting edge from wearing down in rough environments. To keep electrical interference from happening and to make sure measurements are correct in conductive pipe systems, grounding steps must be done exactly as the manufacturer says.
There is a sixteen-digit calibration number on the nameplate of each magnetic flowmeter sensor, which lets suitable receivers set them up perfectly. This original setting keeps the system accurate no matter what line size or extra features are added. Measurement accuracy is checked regularly using troubleshooting methods, so the sensor doesn't have to be taken out of service. Throughout the meter's life, the device diagnostics find and tell of any abnormalities. This lets upkeep plans plan ahead and avoid sudden failures.
Comparing this flanged magnetic flow sensor to other measurement technologies can help you make choices about what to buy and make sure you choose the best option for your needs.
When compared to other magnetic flowmeter designs (Rosemount 8705 Flange type electromagnetic flowmeter sensor), the 8705's fully welded construction protects against the environment better than meters with bolted housings or external junction boxes. The sensor is accurate within 0.15% of volumetric flow over a 13:1 range, which is the same as or better than similar units and makes it easier to use with older emitter types. Backward compatibility saves investments in infrastructure that have already been made and lets systems be upgraded in the future without having to be completely replaced.
When there are a lot of solids or a lot of air moving through the sample, ultrasonic meters don't work very well. This is where electromagnetic devices really shine. Because it can handle slurries and dissolved solids without losing its accuracy, the 8705 is perfect for use in mining and wastewater treatment. Vortex meters need minimum flow speeds and are sensitive to vibrations. This electromagnetic monitor, on the other hand, can correctly measure flows down to almost zero speeds and is not affected by mechanical vibrations. The electromagnetic design doesn't have any moving parts or sensors that stick out, so it doesn't have any of the problems that other technologies do.
Lifecycle costs, not just the original buying price, show what the real value is. The 8705 doesn't need any upkeep, so it doesn't have to be calibrated on a regular basis, as some other technologies do. Repair costs are much lower for meters that can be serviced in the field than for meters that need to be serviced in the factory. Because there are no obstructions, there is no drop in pressure, so energy costs stay low. This is in contrast to restriction-based meters, which require more pumping. The electromagnetic flowmeter usually has the lowest cost per measurement point when you add up all the prices over a normal 15-year service life.
To get something, you need to know about the different ways to get it, the terms of the protection, and the specifications that are needed. These things affect both the success of the job and how reliable it will be in the long run.

Chemical makers have to deal with some of the hardest measurement problems because they have to deal with toxic fluids, high temperatures, and strict requirements for accuracy. The 8705 has shown it can reliably do its job in making sulfuric acid, moving caustic soda, and moving solvents, all of which require material suitability and measurement accuracy that are directly related to product quality. The sensor can work with process fluids that have conductivity as low as 5 microsiemens per centimeter, which means it can be used in a wider range of chemical processes. Plants say that measurements stay the same for years at a time, even when they are used continuously with harsh media.
For process control, legal reports, and billing accuracy, municipal water treatment plants need to be able to measure flow accurately. The 8705 works effectively to measure raw water intake, keep an eye on chemical feed systems, and confirm effluent release. Compared to other technologies, it needs less upkeep because it doesn't get clogged up by suspended solids and organic growth. Water companies like the sensor because it can keep its accuracy over a wide range of flow rates, which means it can handle changes in daily demand without affecting the quality of the measurements. With an IP68 grade and sealed cable connectors, this device can work reliably in wet places like water treatment systems.
Applications that need to be able to accurately pass control need the highest levels of precision and dependability. The 8705 is chosen by petroleum ports and pipeline owners to measure the shift of products when accurate measurements are needed for financial reconciliation. The monitor is stable and has been certified to be accurate, which meets strict standards for ownership transfer. Additional safety is provided by optional secondary containment sections that go around the electrodes and catch any process fluid leaks. This addresses environmental and safety concerns at key measurement spots.
The Rosemount 8705 flange-type electromagnetic flowmeter sensor has been shown to be reliable thanks to smart engineering, strong construction, and a number of setup choices. Its fully sealed housing keeps out environmental problems, and the fact that it can be serviced in the field cuts down on upkeep costs and downtime. The electromagnetic measurement concept gives stable, exact readings in a wide range of situations, without the wear and drift that can happen with other technologies. Compared to other options, the 8705 has a lower total cost of ownership because it requires less upkeep, works with a wide range of chemicals, and lasts a very long time. People in the industrial world who need to measure flow reliably in tough situations will find that the 8705 meets both their short-term and long-term needs.
When placed and taken care of properly, the sensor should last between 15 and 20 years. The design that is entirely welded gets rid of typical weak spots where gaskets or seals wear out. Lifespan depends on the process conditions. For softer uses, it may last longer than 20 years, but for very acidic or rough uses, it may need to be replaced sooner. During routine maintenance, checking the state of the electrodes and liners on a regular basis helps correctly estimate how much service life is left.
In most situations, the sensor's factory setting stays the same over its entire working life. The measurement accuracy is checked once a year using built-in tools, so the unit doesn't have to be taken out of service. Formal recalibration usually doesn't happen until the electrodes are replaced or if proof tests show that the measurements have changed. This is very different from other flowmeter technologies that need to be calibrated once or twice a year, which lowers the total cost of ownership by a large amount.
Depending on the inner material choice, the magnetic flow monitor can handle different process temperatures. Liners made of PTFE can handle temperatures up to 180°C, and some special materials can handle even higher temperatures. If you choose the right cover when you buy it, it will work with the temperature range you need for your purpose. The temperature range is also affected by the type of transmitter placement (integral vs. remote), with remote mounting allowing use in warmer areas.
