Vortex flowmeter simplifies maintenance, reducing installation costs & increasing availability in utility apps!

The Rosemount 8600 Utility Vortex flowmeter is an expansion of Emerson's vortex flowmeter family. Optimised for clean fluid and steam in utility applications, the new flowmeter is available in standard and multivariable versions. Its application specific design simplifies maintenance, reduces installation costs and increases availability.

The unique design of the Rosemount 8600 Utility Vortex flowmeter provides a cost effective solution for a wide range of utility applications. For example, when compared with traditional DP flowmeters, the Rosemount 8600 Utility typically provides a 46 per cent saving on the installed cost (based on a 2” line size installation).

The cast construction of the unit minimises potential leak points and eliminates the need for impulse lines – improving reliability and reducing installed cost. There are no moving parts to wear or stick, and no impulse lines to plug or freeze. The signal filtering (Adaptive Digital Signal Processing-ADSP) and a mass-balanced sensor design, maximise measurement reliability and eliminate the impact of vibrations on measurement accuracy.

For saturated steam applications, a multivariable measurement option on the Rosemount 8600 Utility Vortex provides a temperature compensated mass flow output directly from the meter. Unlike traditional multivariable vortex designs, the Rosemount MultiVariable™ 8600 Utility Vortex has an isolated temperature sensor. This allows the temperature sensor to be verified or replaced without breaking the process seals. Operator safety is enhanced by limiting personnel exposure to process conditions and throughput maximised by eliminating the need to shut down the process to maintain the temperature sensor.

Internal flow simulation diagnostics simplify maintenance, enabling easy field verification of the electronics without the need for additional equipment. With a turndown ratio of 30:1, the vortex linear technology provides accurate measurement over a broader range of flow rates.

This ange comprises seven line sizes from DN25 to DN200 (1 to 8 inches). Each unit is leak tested and factory configured to speed installation and there is no field calibration or zeroing required. Accuracy is ±0.75% of volumetric flow rate in liquid, ±1.0% of volumetric flow rate in gas and steam, ±2.0% of mass flow rate in saturated steam with ±0.2% repeatability. Suitable for process temperatures in the range -50°C to +250ºC, the transmitter can map independent variables to provide an analogue output, pulse output, or HART® burst variables.

It forms part of a broad range of Rosemount Vortex flowmeters for a variety of process and utility applications. The unique features of their Vortex flowmeter simplify installation, maintenance, and meter verification, while improving overall process availability and reducing the total cost of ownership.
