  • Page 9: Principle Of Operation

    Functional principle - in- High frequency microwave impulses are guided along a steel cable or terface measurement rod. Upon reaching the product surface, a part of the microwave im- pulses is reflected. The other part passes through the upper product and is reflected by the interface. The running times to the two product layers are processed by the instrument. GWR-3000 • Modbus and Levelmaster protocol...

You can find further information in the operating instructions manual "Bypass tube VEGAPASS 81".

    Prior to setup you have to replace these protective caps with ap- proved cable glands or close the openings with suitable blind plugs. Note: Process conditions For safety reasons, the instrument must only be operated within the permissible process conditions. You can find detailed information on GWR-3000 • Modbus and Levelmaster protocol...

  • Page 15: Mounting Instructions

    Fig. 5: Vessel with conical bottom Type of vessel Plastic vessel/Glass vessel The guided microwave principle requires a metallic surface on the process fitting. Therefore, in plastic vessels, etc., use an instru- ment version with flange (from DN 50) or place a metal sheet (ø > 200 mm/8 in) beneath the process fitting when screwing it in. Make sure that the plate has direct contact with the process fitting. When mounting rod or cable probes in vessels without metal walls, e.g. in plastic vessels, the measured value can be influenced by GWR-3000 • Modbus and Levelmaster protocol...
  • Page 16 In such cases, always carry out a false signal suppression after mounting. You can find further information under "Setup procedure". DN25 ... DN150 ≤ 150 mm (5.91") > DN150 ...

  • Page 18 In the case of cable probes, the cable can be strained. Keep in mind that the lower dead zone underneath the spacer in- creases if spacers are used. Buildup can form on the spacers. Strong buildup can influence the measurement. GWR-3000 • Modbus and Levelmaster protocol...
  • Page 19 It does not matter if the standpipe is perforated or slotted for better mixing. Measuring probes can be mounted in standpipes up to DN 200. GWR-3000 • Modbus and Levelmaster protocol...
  • Page 20 With rod probes, a spacer is generally not required. However, if there is a risk of the rod probe being pressed against the tube wall by in- flowing medium, you should mount a spacer at the probe end to avoid contact with the tube wall. In the case of cable probes, the cable can be strained. GWR-3000 • Modbus and Levelmaster protocol...
  • Page 21 If there is a risk of the cable probe touching the vessel wall during operation due to product movements or agitators, etc., the measuring probe can be strained. For this purpose there is an internal thread (M12 or M8) in the gravity weight. GWR-3000 • Modbus and Levelmaster protocol...
  • Page 22 Rod extension In case of difficult installation conditions, for example in a socket, the probe can be suitably adapted with a rod extension. To compensate for the resulting changes in signal runtime, let the instrument determine the probe length automatically. You can find further information in the supplementary instructions of the rod and cable components. GWR-3000 • Modbus and Levelmaster protocol...
