Racine Vortex released its RNS Series (Insertion) and RWS Series (Wafer) Vortex Steam Flow Meters. The meters are suitable for measuring non-condensing steam and saturated process steam at pressures up to 150 psi. Leading applications include boiler monitoring and other energy-related uses, as well as building and facilities management.
Both the RNS and RWS series meters have no moving parts and are virtually maintenance-free. All meters in both series are loop-powered devices with standard HART communication for easier field programming and system integration.
Both meters work in operating temperatures of -20°F–366°F. An internal RTD and an optional external pressure sensor provide data to the internal flowmeter software, which compensates for changes in temperature and pressure to achieve an accurate flow measurement. Accuracy of both meters is ±1 percent of reading, with repeatability of 0.5 percent. The RNS and RWS meters are pre-calibrated for specific uses, and can be rescaled in the field

The RNS Series insertion flowmeter is available for pipe sizes from 6”-72” (152-1,829 mm), has a 35:1 turndown ratio, and can be configured for mass flow measurements.
The RWS Wafer meter has 316SS wetted parts, an extremely small bluff bar for little or no pressure drop, and NIST-traceable calibration. It is available in 5 sizes for flange mounting in pipes from ½”-4”.
Options for both meters include ATEX certification, a two-line, 8-digit rate/totalizer display and remote electronics.
