Rosemount 8705 Flanged Magnetic Flow Meter Sensors provide long-lasting, reliable performance in even the most challenging applications. An all-welded construction provides a hermetic seal that protects against moisture and other contaminants. The sealed housing ensures maximum sensor reliability by protecting all internal components and wiring from even the most aggressive environments. A removable and replaceable terminal block enables easy repair in the field without the need to replace the entire meter.
· For maximum protection, a fully welded sensor housing provides a hermetic seal
· Avoid process shutdown with a removable and replaceable terminal block that enables repairs in the field
· Capture any potential process fluid leakage with optional secondary containment compartments to surround electrodes
· Ensure reliability in the harshest environments with an all-welded sensor housing
· Guard against installation damage and leading-edge wear with an optional lining protector
· Minimize maintenance and repair with an obstructionless design featuring no moving parts
