Racine Vortex has released the RNS series (insertion) and RWS series (wafer) vortex steam flowmeters.

The meters are suitable for measuring non-condensing steam and saturated process steam at pressures up to 150psi.

Typical 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 the meters in both series are loop-powered devices with standard Hart communication to facilitate field programming and system integration.

Both meters work in an operating temperature range of -20F to 366F.

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.

The accuracy of both meters is +/-1 per cent of reading, with a repeatability of 0.5 per cent.

The RNS and RWS meters are pre-calibrated for specific uses and can be rescaled in the field with the use of the provided PC-based software program.

The RNS series insertion flowmeter is available for pipe sizes from 6in to 72in (152mm to 1,829mm), has a 35:1 turndown ratio and can be configured for mass flow measurements.

The RWS wafer meter has 316SS wetted parts, a small bluff bar for little or no pressure drop and NIST-traceable calibration.

It is available in five sizes for flange mounting in pipes from 0.5in to 4in.

Options for both meters include ATEX certification, a two-line eight-digit rate/totaliser display and remote electronics.
