*   All welded, non-clog design provides maximum performance, reliability and enhanced safety by eliminating ports and gaskets. No seals, just steel.
*   Available with optional output. Internal temperature compensation provides cost-effective saturated steam mass flow measurement.
*   Adaptive Digital Signal Processing provides vibration immunity and flow range optimization.
*   Vortex extends the measurable flow range, reduces installation costs, and minimizes project risk.
*   Available in wafer, flanged, and high pressure designs.
