Description

SITRANS WF100 flowmeter is a low- to medium-capacity flowmeter for various product sizes,
densities, and fluidities in restricted spaces. This compact unit improves processing, increases
operating efficiency, and helps provide significant cost savings.
Operating with a microprocessor-based Siemens integrator, the Milltronics SF500 displays
flowrate, 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 flowguide producing a mechanical deflection as they strike the
flowmeter sensing plate before continuing through the process unhindered. A strain gauge load
cell converts the horizontal force of the deflection into an electrical signal. The integrator
processes this to display the flowrate and integrated total weight. The process is immune to the
effect of product build-up as only horizontal force is measured.
WF100 features easy installation into standard pipe sizes, simple operation, and fast and
accurate flow response. WF100 is an accurate and repeatable force sensor and its performance
depends on consistent flow of material flow in and the quality of the installation.
