The Rosemount 8721 is a high-performance sanitary flow meter engineered specifically for industries where purity and safety are non-negotiable. Designed for food, beverage, and life science applications, the 8721 features an all-welded, lightweight stainless steel body that meets stringent 3-A and EHEDG standards. At Hanyuzl, we understand the complexities of sterile processing, offering the 8721 as a reliable, CIP/SIP cleanable measurement solution that ensures your production line remains compliant and efficient.
In hygienic environments, the materials in contact with the media are critical. The Rosemount 8721 utilizes FDA-approved PFA liners and 316L Stainless Steel electrodes to prevent contamination.
The 8721’s sensor ID perfectly matches the process piping, eliminating hard-to-clean step changes or "dead zones" where bacteria can grow. This obstructionless design not only ensures the highest hygiene levels during Clean-in-Place (CIP) and Steam-in-Place (SIP) cycles but also reduces pressure drop and maintenance costs.

To ensure long-term reliability in Grade A milk processing or pharmaceutical dosing, consider:
Connection Type: Tri-Clamp® is the standard for quick disassembly, while Weld Nipples are preferred for permanent, high-integrity lines.
Electrode Choice: Use Platinum electrodes for highly corrosive cleaning agents or aggressive life science media.
Transmitter Pairing: The 8721 is interchangeable with the Rosemount 8732 transmitter, allowing for advanced diagnostics like "High Process Noise" detection.
Orientation: For hygienic reasons, vertical installation with upward flow is best to ensure the pipe is always full and self-draining.
Gasket Access: Ensure the meter is installed where process gaskets are easily accessible for routine inspection.
Grounding: Proper grounding is essential for signal stability; use grounding rings if installing in non-metallic or lined piping.
The 8721’s all-welded construction eliminates gaskets within the meter body, reducing the risk of leaks.
Daily Inspection: Thanks to the easily accessed sanitary connections, technicians can quickly verify seal integrity.
Smart Diagnostics: When paired with modern transmitters, the 8721 can detect electrode coating, alerting you to build-up before it affects measurement accuracy.
