Products Description
The flangeless design of the Rosemount 8711 Wafer Magnetic Flow Meter Sensor makes it an economical, compact and lightweight alternative to flanged magnetic flowmeters. Choose from a wide range of rugged liner and electrode material options compatible with virtually all applications, from highly corrosive liquids to fibrous slurries often considered difficult to measure with other devices. For easy installation, alignment spacer kits are provided with every 8711 meter to center the sensor in the process line.
Features
- Cut costs with a flangeless construction for minimum size and weight
- Compact shape is ideal for installation in locations with limited amount of straight run pipe
- Suit any process application with available rugged liner options and standard, grounding and bullet-nose electrodes
- Simplify installation with a lightweight, flangeless design
- Eliminate gaskets and prevent moisture ingress with an all-welded sensor
- Minimize maintenance and repair with an obstructionless design featuring no moving parts
- Avoid process shutdown with a removable and replaceable terminal block that enables repairs in the field
Key Advantages
1. Easy Installation, Saves Cost and Space
· Wafer Design: Eliminates the need for flanged connections, significantly reducing installation costs for bolts, gaskets, and labor.
· Compact and Lightweight: Ideal for space-limited locations and reduces pipe support requirements.
2. Easy Maintenance and Inspection
· Can be quickly disassembled from the pipeline for sensor inspection, cleaning, or maintenance, especially suitable for production lines with regular CIP (Clean-in-Place) or batch changeover requirements.
3. No Moving Parts, High Reliability
· The magnetic flow measurement principle means there are no moving parts inside, resulting in no pressure loss and minimal wear, ensuring long-term measurement stability and low maintenance.
4. Wide Fluid Compatibility
· Offers a variety of liner and electrode material options to handle everything from clean water to corrosive chemicals and slurries.
5. High-Performance Measurement
· When combined with the 8700 series transmitter, it achieves measurement accuracy up to ±0.5% and provides excellent repeatability for reliable process control data.
