VEGAPULS WL 61 - 4 … 20 mA/HART - two-wire

4 Mounting1Fig. 14: Position of the polarisation level1 Marking barInstallation positionWhen mounting the sensor, keep a distance of at least 200 mm(7.874 in) to the vessel wall. If the sensor is installed in the center ofdished or round vessel tops, multiple echoes can arise. These can,however, be suppressed by an appropriate adjustment (see chapter"Setup").If you cannot keep this distance you should carry out a false echostorage before setup. This applies mainly if buildup on the vessel wallis expected. In this case, we recommend repeating a false echo storagelater with existing buildup.> 200 mm(7.87")Fig. 15: Mounting of the radar sensor on round vessel topsIn vessels with conical bottom it can be advantageous to mount thesensor in the center of the vessel, as measurement is then possibledown to the lowest point of the vessel bottom.18VEGAPULS WL 61 • 4 … 20 mA/HART - two-wire38061-EN-121011
