SITRANS WF solids flowmeters monitor the rate of bulk material
flow in a process. They continuously measure the impact force
of the material under gravity feed conditions, and convert this
signal into a flow rate used to control the rate into a process or
blending operation.
Solids flowmeters can function in standalone measuring operations, or they can interface to a facility’s
process control system using industry standard protocols

SITRANS WF100 flowmeter is a low to medium capacity flowmeter for various product sizes, densities, and fluidities in restricted spaces.
WF100 is unaffected by corrosive, abrasive, or hot materials.
Handling various product sizes, densities, and fluidities including fine powders such as sugar, the WF100 helps to improve final product, increase operating efficiency, and realize significant
cost savings.
Dry bulk solids enter the flow guide producing a mechanical deflection as they strike the flowmeter sensing plate before continuing through the process un-hindered. The WF100 converts
the deflection into an electrical signal that feeds into an accompanying integrator, which instantaneously displays the flow rate
and totalizes the weight.
SITRANS WF200 and WF250 flowmeters are medium to high capacity flowmeters for various product sizes, densities, and fluidities.
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).
SITRANS WF300 series are low to medium capacity flowmeters for various product sizes, densities, and fluidities.
With weighing mechanics located externally, the WF300 series
solids flowmeters are unaffected by corrosive, abrasive, or hot
materials. Handling a wide range of product sizes, densities,
and fluidities including fine powders such as cement, they operate at process temperatures to 230 °C (450 °F). The flowmeters
help to improve final product, increase operating efficiency, and
realize significant cost savings.
Operating with the appropriate SITRANS WFS sensing head and
a micro-processor-based integrator package, the WF300 series
flowmeters provide a display of the flow rate, totalized flow, and
alarms. Outputs are 0/4 to 20 mA proportional to rate, and open
collector output for remote totalization.
Dry bulk solids enter the flow guide producing a mechanical deflection as they strike the flowmeter sensing plate before continuing through the process unhindered. The LVDT in the sensing head converts the deflection of the horizontal force into an
electrical signal. The integrator processes this signal into a display of flowrate and integrated total weight. The weighing process is immune to the effect of product build-up as only the horizontal force is measured.
SITRANS WF330 flowmeters are totally enclosed, with external
weighing mechanics, operating with corrosive, abrasive or hot
materials. SITRANS WF350 series operates with aerated gravity
conveyors, and includes integral vents and baffles for air separation. For applications with little available headroom, the
SITRANS WF340 series flowmeters provide the answer.
SITRANS WFS300 and WFS320 sensing heads are out-of-the process sensing elements for SITRANS WF300 series solids flowmeters.
SITRANS WFS300 and WFS320 sensing heads are used in applications such as product rationing, batch load-out, and process feed rate control, the WFS series of sensing heads has
been field-proven in thousands of applications with some units
providing over a quarter century of reliable performance.
The WFS sensing heads use only the horizontal force created by
impact of product upon the sensing plate and then apply the
horizontal deflection to a highly reliable linear variable differential
transformer (LVDT).
Friction-less pivots exclude the vertical force from the sensing
process and the LVDT travel range is controlled by a coil spring
selected for the specified full-scale flow rate. A viscous fluid
damper provides mechanical damping in the event of pulsating
flows.
The LVDT converts the horizontal movement, proportional to the
impact forces into an electrical signal, which is converted by the
integrator to time-based flow rate indication and totaling. This
method of sensing material flow has been proven best in thousands of applications all over the world.

The sensing plate transfers the impact force to the sensing head of the flowmeter.
Milltronics BW500 is a full feature integrator for use with both belt
scales and weighfeeders.
Milltronics BW500/L is an integrator for use in basic belt scale or
weighbelt applications.
Milltronics BW500 and BW500/L operate with a belt scale and a
speed sensor. Belt load and speed signals are processed for accurate flow rate and totalized weight of bulk solids.
BW500 can take on lower level control functions traditionally
handled by other devices, and it supports popular industrial
communication buses. Its proven load cell balance function
eliminates matching of load cells.
The PID function may be used for rate control on shearing weighfeeders - where belt loading is constant - but can also control
pre-feeding devices. Operating in tandem with two or more
weighfeeders, the BW500 may be used for ratio blending and
controlling additives. Batching, load out, and alarm functions are
also provided by the BW500.
Dolphin Plus software may be used for programming the unit on
a PC.
