Key Features
- Quad vortex flow measurement with two-out-of-three voting
- Fourth integrated transmitter for process control
- 4-20 mA with HART 5 or 7
- Optional scalable pulse output
- Turndown: 15:1
- Gasket-free, non-clog meter body
- Dual shedder bars, quadrupole sensors, and quadrupole sensing elements
- Isolated sensor design for online replacement
- IEC 61508 certified for use in safety instrumented systems up to SIL 3 with 2oo3 voting
Applications
This series is suitable for liquid, gas, and steam flow measurement in industrial applications where redundant measurement, higher safety integrity, and improved plant availability are required. It is especially suitable for users who want to reduce maintenance risk and guard against false trips.
