Overview
The Rosemount 8800 Dual Vortex Flow Meter provides a redundant flow measurement solution designed to protect against false trips using one-out-of-two or two-out-of-two voting. It combines world-class reliability with a gasket-free, non-clog meter body to help improve process availability and reduce unscheduled shutdowns.
Key Features
- Redundant dual vortex flow measurement
- One-out-of-two or two-out-of-two voting
- 4-20 mA with HART 5 or 7
- Optional scalable pulse output
- Turndown up to 38:1 for single bar duals and 15:1 for dual bar duals
- Gasket-free meter body design
- Isolated sensor for online replacement without breaking the process seal
- Compact solution with dual sensors, sensing elements, and transmitter configuration
- IEC 61508 certified for use in safety instrumented systems up to SIL 3 with 1oo2 voting
Applications
This series is suitable for liquid, gas, and steam flow measurement in industrial applications where redundant measurement and higher functional safety are required. It is well suited for users who want to improve plant availability while reducing maintenance risk and false trips.
