For over 50 years, wedge flowmeters have served as a rugged alternative for measuring abrasive, viscous, and erosive fluids that challenge conventional DP flowmeters. While effective, these systems traditionally required costly custom engineering and specialized maintenance. Emerson’s new Rosemount 9195 Wedge Primary Element transforms this legacy technology into a standardized, plug-and-play solution for modern industrial demands.
Engineered for Extreme Process Conditions
The 9195 series combines four breakthrough features:
- ISO 5167-6 compliant wedge design eliminates sharp edges to withstand slurries and particulates
- Preconfigured remote-seal assemblies simplify installation across -18°C to 410°C environments
- Modular connection styles adapt to space-constrained installations
- Erosion-resistant construction maintains accuracy in mining, refining, and carbon capture applications
Five Tailored Packages Replace Custom Builds
Emerson replaces bespoke configurations with application-optimized packages:
- Standard: Water/wastewater processing
- Abrasive: Mining slurries & metal recycling (thickened diaphragms)
- Ultra-HT: Refinery flows up to 410°C
- Cold-Weather: Arctic pipeline monitoring
- Remote-Mount: Compact plant installations
“Now instead of engineering each meter, users select from validated configurations based on their media – whether it’s lithium slurry or asphalt,” explains David Wright, Emerson’s DP Flow Product Manager.
Smart Integration with Rosemount Transmitters
When paired with Emerson’s 3051S DP transmitters, the system delivers:
- 14:1 flow turndown with Ultra for Flow precision
- WirelessHART/Battery operation for remote sites
- 15-year stability warranty – unprecedented in wedge flow measurement
- Foam/entrainment diagnostics to predict process anomalies
Future-Proofing Industrial Flow Measurement
With support for Fieldbus, Modbus, and HART protocols, the 9195 bridges legacy and IIoT systems. Its standardized approach reduces deployment time from weeks to days while cutting lifecycle costs – a critical advantage for carbon capture projects and battery mineral processing driving today’s energy transition.
This innovation marks a paradigm shift: specialist measurement becomes mainstream infrastructure, empowering industries to monitor harsh flows with unprecedented simplicity and reliability.
