The Rosemount 8705 Flange type electromagnetic flowmeter sensor has great accuracy and durability. This modern sensor is fully protected from wetness and dirt because it is all-welded. This electromagnetic flowmeter sensor gives you reliable, accurate readings that you can trust for years, no matter if you work in petrochemicals, power production, or water treatment.

Industrial processes need equipment that works well in tough situations. The fully sealed design of the Rosemount 8705 makes it the most durable option available. You will be glad that the all-welded case keeps the parts inside safe from erosion and damage from the environment.
The sensor's new design gets rid of frequent upkeep problems. You can do field repair without having to swap out the whole unit if the connections can be taken off and put back on. This feature cuts costs and time while also minimizing process downtime.
Advanced Protection Features
Your process efficiency depends on tools that can work in tough conditions. The sealed case design keeps chemicals, weather, and other things that can damage the device out. Even in the most difficult industrial environments, the inside parts stay safe and working.
The extra containment shell around the wires is not required, but it makes things safer. This feature lets you check for any possible process liquid leaks, which can help ease your mind during important tasks.
