Explore Rosemount 8711. A lightweight, flangeless wafer magnetic flow meter. Features 0.15% accuracy, ETFE/PTFE/PFA liners, and all-welded sensor design.
The Rosemount 8711 Wafer Magnetic Flow Meter Sensor offers an economical, compact and lightweight alternative to traditional flanged magnetic flowmeters. Its flangeless design is specifically engineered to cut costs by reducing overall size and weight, making it the ideal wafer magnetic flowmeter for process lines with limited space.
Designed for versatility, the 8711's compact shape is ideal for installation in locations with a limited amount of straight run pipe. By utilizing a flangeless construction, this sensor allows for minimum size and weight without sacrificing performance. If your application lacks the space even for a wafer design, you might consider our Clamp-on Ultrasonic Flowmeters for a completely non-invasive solution.
The Rosemount 8711 is built to handle the toughest process applications, from highly corrosive liquids to fibrous slurries often considered difficult to measure. It features a wide range of rugged liner materials, including ETFE, PTFE, and PFA. For specialized mass flow requirements in similar corrosive environments, our Coriolis Mass Flow Meters offer unmatched precision.
Engineered for long-term durability, the 8711 features an all-welded sensor that eliminates gaskets and effectively prevents moisture ingress. Its obstructionless design contains no moving parts, which serves to minimize maintenance and repair. Additionally, a removable and replaceable terminal block enables field repairs, helping operators avoid process shutdown.
Precision is at the core of the 8711, delivering up to 0.15% of volumetric flow rate accuracy over a 13:1 flow turndown. This sensor is designed for interchangeability, maintaining compatibility with all Rosemount 8700 Series transmitters as well as legacy transmitters.

Q: What makes the Rosemount 8711 an economical choice?
A: Its flangeless (wafer) design reduces the size and weight of the sensor, making it a lower-cost alternative to flanged meters without compromising performance.
Q: Can the 8711 handle difficult fluids like slurries?
A: Yes. Its obstructionless design and availability of rugged liners (like ETFE/PTFE) and specialized electrodes make it ideal for corrosive liquids and fibrous slurries.
Q: Is the Rosemount 8711 compatible with older Rosemount transmitters?
A: Absolutely. It is interchangeable with all 8700 Series transmitters and legacy models, including the 8712D, 8732C, and 8742C.
Q: How does the all-welded design benefit the user?
A: The all-welded sensor housing eliminates gaskets, which prevents moisture ingress and ensures long-term reliability in harsh environments.
