Flowmeter provides flexibility to achieve improved measuring performance

Products electromagnetic Endress+Hauser flowmeters

The Endress+Hauser Proline Promag W electromagnetic flowmeter for the water/wastewater industry has a new 0 x DN full bore option said to deliver great measurement accuracy without any measuring tube restriction — irrespective of the flow profile or mounting location.

Maximum measurement performance is indispensable for optimal process control but in some circumstances is difficult to achieve. Plant operators may have to compensate for flow disturbances by adopting the recommended inlet and outlet runs or by employing a flow measuring device with a restricted measuring tube. However, sufficiently long straight pipe sections may not be not available for the former, while tube restrictions cause pressure loss that often leads to increased energy consumption for pump operations and higher energy costs.

The Endress+Hauser solution is provided by the innovative measuring concept of Promag W 300/400/500 flowmeters with 0 x DN full bore, the company says. Each flowmeter features multiple measuring electrodes to detect abnormalities in the flow that can impact measurement accuracy. This generates a substantially higher density of measured data than for standard devices. Measurements aren’t distorted by frequently occurring swirls caused by Influences such as a close-knit pipeline network or obstacles in the pipe cause flow turbulence that affect accuracy. These obstacles can include pipe bends and insertion devices or unknown obstacles such as build-up on the pipe wall, protruding seals or different inside diameters.

The flowmeters with the 0 x DN full bore option are particularly well-suited for installation in tight spaces, such as compact systems or skids, because they do not need any inlet or outlet runs. They can be equipped with different Proline transmitters: as a compact version (Proline 300 and 400) or as a remote version (Proline 400 and 500) with up to four outputs. Proline transmitters make no compromises in terms of performance and accuracy. The digital signal processing begins in the intelligent sensor and is the basis for a reliable, highly accurate measurement. Full access to all measurement data, including diagnostic data acquired by the company’s proprietary Heartbeat Technology, is possible at any time thanks to digital data transmission or the freely combinable inputs and outputs.
