    During work on and with the device the required personal protective equipment must always be worn. Appropriate use VEGAPULS WL 61 is a sensor for continuous level measurement. You can find detailed information about the area of application in chapter "Product description". Operational reliability is ensured only if the instrument is properly used according to the specifications in the operating instructions manual as well as possible supplementary instructions.

  • Page 9: Principle Of Operation

    Principle of operation Application area The radar sensor VEGAPULS WL 61 is the ideal sensor for all appli- cations in the water and waste water industry. It is particularly suitable for level measurement in water treatment, in pump stations as well as storm water overflow tanks, for flow measurement in open flumes and for gauge measurement.

    Mounting bracket For a rigid mounting, a mounting bracket with opening for thread G1½, e.g. from the VEGA product range, is recommended. The mounting of the sensor in the bracket is carried out via a G1½ counter VEGAPULS WL 61 • Foundation Fieldbus...
  • Page 12 The instrument is normally mounted vertically with a bracket on the mounting ceiling. This ensures swivelling of the sensor up to 180° for optimum orienta- tion. Fig. 4: Ceiling mounting via the mounting strap with length 300 mm VEGAPULS WL 61 • Foundation Fieldbus...

    The emitted radar impulses of the radar sensor are electromagnetic waves. The polarisation is the direction of the electrical wave compo- nent. By turning the instrument in the connection flange or mounting strap, the polarisation can be used to reduce the effects of false echoes. The position of the polarisation is marked by marking bars on the instrument. VEGAPULS WL 61 • Foundation Fieldbus...
  • Page 15 Fig. 10: Mounting of the radar sensor on round vessel tops In vessels with conical bottom it can be advantageous to mount the sensor in the center of the vessel, as measurement is then possible down to the lowest point of the vessel bottom. VEGAPULS WL 61 • Foundation Fieldbus...
  • Page 16 Approximate values of the socket heights are shown in the following illustration. The socket end should be smooth and burr-free, if possi- ble also rounded. After mounting, you have to carry out a false signal memory during the parameter adjustment. VEGAPULS WL 61 • Foundation Fieldbus...
  • Page 17 Make sure when planning your measuring point that the radar sensor has a "clear view" to the measured product. In case of existing vessel installations, a false echo storage should be carried out during setup. VEGAPULS WL 61 • Foundation Fieldbus...
