  • Page 11: Description

    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.
  • Page 12 Description Components Siemens flowmeters react to the horizontal component of force created by the impact of material on the sensing plate. Siemens flowmeters consist of two physical components: ● the housing which includes the flowguide and the outlet: supports the sensing assembly and guides the material flow ●...
  • Page 13 The displacement of the load cell is sensed by its strain gauges. These convert the excitation signal from the electronic integrator to produce a signal proportional to material flow. ① Positive stop ② Negative stop SITRANS WF100 Operating Instructions, 02/2012, 7ML19985NB01-01...
