  • Page 7 Safety notes 2.2 Installation in hazardous areas Instructions specific to hazardous area installations (Reference European ATEX Directive 2014/34/EU, Annex II, 1/0/6) The following instructions apply to equipment covered by certificate number SIRA 11ATEX9367X, and CSAE 21UKEX9105X: 1. For use and assembly, refer to the main instructions. 2.
  • Page 8 Safety notes 2.2 Installation in hazardous areas Conditions for safety use • The equipment shall be installed such that the supply cable is protected from mechanical damage. The cable shall not be subjected to tension or torque. If the cable is to be terminated within an explosive atmosphere, then appropriate protection of the free end of the cable shall be provided.

  • Page 9: Description

    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.
  • Page 10 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 11 Description Horizontal sensing plate The material travels down the flowguide, striking the sensing plate and discharging through the outlet. The force exerted on the sensing plate has both a vertical and horizontal component. The design of the load cell is such that it reacts to the horizontal component only;...
  • Page 12 Description Negative displacement A negative stop protects the load cell against excessive negative displacement which could functionally destroy it. The negative stop is factory set so that the output signal is limited to - 20 mV when the load cell is forced to travel in the negative direction. Under no-flow conditions, the load cell/sensing plate assembly is at rest at static zero.

  • Page 13: Material Feed Examples

    Description 3.1 Material feed examples Location Materials with low moisture content generally have excellent flow and adhesion characteristics. In processes where material moisture content varies, select a flowmeter location where the moisture content is lowest. Linings • Sensing plate abrasion resistant linings are often used for aggregates, barley, corn, soybeans, wheat, and material with similar hardness and particle mass.
  • Page 14 Description 3.1 Material feed examples Bucket elevators • commonly used for grain applications • feeder discharge damping required when slow elevators (typically chain drive) produce heavily pulsing material discharge • use deadbox if required to reduce material velocity from fast elevators (typically re-inforced belt drive) Conveyor belt •...
  • Page 15 Description 3.1 Material feed examples Feeder/flowguide transition • reverse flowguide transition reverses direction of the bin or feeder material discharge before the material enters the flowmeter flowguide • reversing direction forces the material into a desirable flow pattern rather than permitting material to be flung from the feeder, directly into the flowguide •...
  • Page 16 Description 3.1 Material feed examples Long fall chute • material in-feed where the bin or feeder discharge/flowguide fall is more than 0.6 m (2 ft) • less desirable than the short fall chute because material velocity is greater, increasing flowmeter component abrasion •...
  • Page 17 Description 3.1 Material feed examples Pulsing feeder discharge damping • install a temporary holding bin to receive pulsing material discharge from a feeder. Then the material is gravity fed from the bin to the flowmeter flowguide. • provide manual or automatic control to ensure the holding bin is neither emptied nor overfilled while the feeder is in operation.
  • Page 18 Description 3.1 Material feed examples Flowguide capacity CAUTION If either the material bulk density and flowrate is near the flowmeter's in-feed diameter upper limit, choose the next largest diameter. Refer to the following chart to ensure the flowguide capacity is suitable. Figure 3-1 Flowguide capacity chart SITRANS WF100...

    Refer to the integrator instruction manual for programming and calibration details and for information about material tests. All operating instructions are available for download from our website: Siemens weighing (http://www.siemens.com/weighing) Test rate The test rate is the material flowrate represented by the test weight. The test weight is used to simulate the horizontal forces of the material hitting the sensing plate.
  • Page 24 Commissioning For example: If the design flowrate is 6 T/H, then: Therefore the test weight should be between 162 and 216 g. If an available test weight of 200 g is used, then: Perform the zero calibration as described in the Calibration section of the integrator manual. After the completion of the zero calibration, a span calibration, as described in the integrator instruction manual, can be performed with the test weight(s) applied.
  • Page 25 Commissioning Span 1. Install the calibration pulley to the bracket on the flowmeter housing. 2. Hang the test weight over the calibration pulley using the test weight cable. 3. Perform the span calibration as described in the calibration section of the integrator instruction manual.
  • Page 26 At least two 5 minute samples should be taken to ensure repeatability. Refer to material test and subsequent factoring of the flowmeter sections of the integrator manual.
