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
