If you're looking for a safe way to measure flow, the Rosemount 8705 Flange type electromagnetic flowmeter sensor is the best on the market and was made for harsh industrial settings. This high-tech Rosemount 8705 Flange type electromagnetic flowmeter sensor is very accurate and long-lasting because it is hermetically sealed and all welded together, which keeps moisture and other environmental contaminants out. This Rosemount 8705 Flange type electromagnetic flowmeter sensor works consistently and doesn't need to be maintained, so industrial engineers and procurement managers can rely on it for important process control tasks. It can be used in petrochemical processing, power generation, water treatment, or chemical manufacturing.
To measure flow accurately, you must first understand what makes this sensor technology so useful in industrial settings.
All-weld stainless and carbon steel construction makes a hermetic seal, which is what makes this Rosemount 8705 Flange type electromagnetic flowmeter sensor really different from others. This way of engineering gets rid of possible leak paths where water and other acidic substances could damage electronics inside. The sealed housing protects all the wiring and internal parts, so it will still work even if it's exposed to harsh chemicals, high temperatures, or high-pressure washdown environments that are common in food and drug processing plants.
Faraday's Law of Electromagnetic Induction says that conductive fluids moving through a magnetic field create a voltage that is related to the speed of the flow. This is how Rosemount 8705 Flange type electromagnetic flowmeter sensors work. Process liquids must have a conductivity of at least 5 microsiemens per centimetre for the system to work. This means that it can handle water-based solutions, slurries, and most industrial fluids, but not solvents or pure water. The accuracy of the measurement can reach 0.15% of the volumetric flow over a 13:1 turndown range, and the diameter choices run from 1/2 inch to 36 inches. Different chemical compatibility needs can be met by liner materials like PTFE, PFA, and polyurethane rubber. Electrode options include standard 316L stainless steel as well as rare materials like tantalum and platinum for very corrosive uses.
Long-term measurement accuracy and reliability are directly affected by how well the equipment is installed. As the site is prepared, straight pipe runs with five-inch diameters upstream and two-inch diameters downstream should be made so that fully developed flow profiles can be found. The Rosemount 8705 Flange type electromagnetic flowmeter sensor can be mounted either horizontally or vertically, but keeping the electrodes on a horizontal plane stops air bubbles from interfering. Connecting the sensor body and process pipes to earth ground is part of grounding practices. Grounding rings are recommended for pipes made of materials that don't conduct electricity. The design of the removable terminal block makes field wiring easier and lets maintenance be done in the future without having to shut down the process or replace the whole meter.
To make smart choices about what to buy, you need to compare the success of one solution to that of other solutions on the market.
When compared to competitors like the Siemens SITRANS FM MAG and Endress+Hauser Promag flowmeters, the Rosemount 8705 Flange type electromagnetic flowmeter sensor has similar accuracy specs. However, it stands out because its housing is better protected, and it can be serviced in the field. Independent case studies from local water treatment plants show lower total costs of ownership over ten-year operating periods. This is mostly because upkeep tasks are reduced and calibration times are increased. The fully welded design gets rid of the problems with seal failures that happen with bolted housing designs, especially in outdoor settings where temperatures change, and UV light hits the housing.
The extra secondary containment box around the electrodes adds another layer of safety by stopping any process fluid leaks before they reach the outside world. This feature is useful when handling dangerous materials because even small leaks need to be reported to the government. The liner protector accessory protects against damage during installation and stops leading-edge erosion in abrasive slurry applications. This effectively extends the Rosemount 8705 Flange type electromagnetic flowmeter sensor's useful life in tough process conditions. The full Rosemount 8700 series transmitter family is compatible, even the older 8712D and 8732C models. This saves current infrastructure investments and allows for a gradual modernisation of the system.
The Rosemount 8705 Flange type electromagnetic flowmeter sensor is useful for industrial water treatment because it can stay accurate even when the conductivity level and suspended solids content change. Chemical processing settings, like different mixtures of liner and electrode materials, allow for a wide range of chemical compatibility. Power plants depend on high-pressure rates of up to ANSI Class 2500 to monitor boiler feedwater and wastewater return. The dependability of the measurements has a direct effect on how well the plant works and how safe the equipment is.
To get the best procurement results, good sourcing strategies balance the quality of the products, the dependability of the suppliers, and the total cost of acquisition.
As an official Emerson Rosemount instrumentation dealer in Asian markets, Shaanxi Honglixing Electronic Technology Co., Ltd. gives customers direct access to real goods that come with full manufacturer guarantees.

When you sign a bulk purchase deal, you can get discounts for buying more and get first choice during times of high market demand. Delivery times usually range from two to four weeks, but they depend on how complicated the setup is and how much inventory is available.
The cost of a Rosemount 8705 Flange type electromagnetic flowmeter sensor depends on the diameter of the pipe, the material chosen for the liner, the makeup of the electrodes, the pressure values for the flange, and any extra features that are chosen, such as secondary containment or liner protectors. Standard configurations in popular sizes usually have better prices and wait times than mixtures of unusual materials. Framework agreements that last a year and commit to minimum purchase volumes often get better prices and faster delivery times. When you buy compatible Rosemount 8700 series transmitters along with compatible sensors, you can make system packages that lower the overall cost of the project and make sure that all of the parts work together.
Standard manufacturer warranties cover both materials and workmanship for 12 months from the date of shipment. Service agreements can be used to get longer warranties. Our technical support team offers pre-sale application advice to make sure the right Rosemount 8705 Flange type electromagnetic flowmeter sensors are chosen, installation help during the setup phases, and ongoing troubleshooting support for the entire lifetime of the product. To keep downtime to a minimum during rare service events, regional service centers keep calibration equipment and replacement parts in stock. Training programs teach customer support staff how to diagnose problems and do preventative maintenance, which makes equipment more reliable.
Measurement precision and working continuity are protected by proactive repair plans and the ability to solve problems quickly.
Because there are no obstructions, there are no moving parts that need to be replaced on a regular basis in mechanical flowmeters. As part of regular maintenance, cable connections should be visually checked every three months, and the integrity of the grounding system should be checked once a year. During planned shutdowns, process links should be checked for gasket quality and flange bolt torque. The detachable terminal block lets you test electrical continuity without touching the process pipes. This lets you do diagnostic checks without stopping production.
When the Rosemount 8705 Flange type electromagnetic flowmeter sensor is made, it is calibrated in the factory to set a baseline level of accuracy across its flow range. The unique sixteen-digit identification number on the nameplate stores the calibration data. You can use local operator interfaces or HART communication protocols to enter this calibration code into compatible transmitters. This will set the transmitter up automatically for best performance. Field recalibration should be done every three to five years under normal working conditions. Portable ultrasonic flowmeters should be used for verification tests once a year, or reference standards should be compared during process shutdowns.
One common diagnostic indicator is empty pipe detection, which lets operators know when the flow of a process stops or a pipe drains, which stops wrong flow readings. Electrode coating alerts find insulating layers that could affect the accuracy of measurements, so they need to be cleaned up before they start to fail. Transmitter tests check the resistance of the coil and the quality of the insulation. This finds possible wiring problems or water getting in before the transmitter fails completely. When testing shows that Rosemount 8705 Flange type electromagnetic flowmeter sensor problems can't be fixed in the field, our technical support team offers quick advice and arranges for the delivery of new parts to keep production as low as possible.

Process fluids with a conductivity of at least 5 microsiemens per centimetre are needed for the sensor. Most water-based solutions, slurries, and conductive liquids can pass through this threshold. However, hydrocarbons, distilled water, and solutions that aren't water-based can't. For uses with deionised water or fluids with low conductivity, technical experts should be consulted to make sure the product is right.
The interchangeable terminal block lets electrical work be fixed and rewired without taking the sensor out of the stream or stopping the process. Maintenance workers can fix broken terminals, test for continuity, or improve wire connections, all while the sensor is still in place. This cuts down on repair time by a huge amount and avoids the expensive process shutdowns that come with replacing the whole meter.
The sensor works with all Rosemount 8700 series transmitters, both new ones and older ones like the 8712D, 8712C, 8732C, and 8742C. This wide compatibility protects investments in existing infrastructure and lets you design a flexible system or do upgrades in stages without having to replace all of its parts at once.
