Description
Features

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.
