© Siemens AG 2015 Solids Flowmeters LVDT flowmeters SITRANS WF200 series ■ Overview ■ Application Operating with a microprocessor based integrator package, the WF200 series flowmeters display flow rate, totalized flow, and rate alarms. Outputs are 0/4 to 20 mA proportional to rate and contact closure for remote totalization. Dry bulk solids enter the flowmeter before continuing through the process unhindered. The load cells convert the horizontal force of the deflection into an electrical signal. The integrator processes this into flowrate and integrated total weight. The sensing process is immune to the effect of product build-up as only the horizontal force is measured. With load cells located externally to the process, the WF200 series flowmeters measure high capacities with a maximum rate of 900 t/h (990 STPH). For high capacity aerated gravity conveyor pre-feed, the WF250 has a maximum rate of 900 t/h (990 STPH). Key applications • Aggregates • Grain • Cement • Mineral processing 6 SITRANS WF200 and WF250 flowmeters are medium to high capacity flowmeters for various product sizes, densities, and fluidities. ■ Benefits • • • • For specialized pre-feed applications Sensing element mounted outside process Flowrates from 200 to 900 t/h (220 to 990 STPH) Continuously monitoring of the material flow without interrupting the process • Dust-tight construction: suitable for use in hazardous areas and in washdown applications that require frequent cleaning • Minimal maintenance or recalibration after the initial installation and material tests Siemens WT 10 · Update 04/2015 6/11 © Siemens AG 2015 Solids Flowmeters LVDT flowmeters SITRANS WF200 series ■ Selection and ordering data 1) SITRANS WF200 series flowmeters SITRANS WF200 and WF250 flowmeters are medium to high capacity flowmeters for various product sizes, densities, and fluidities.
