4 Mounting> <strong>20</strong>0 mm(7.87")Fig. 8: Vertical mounting on the wall via the mounting strap with length 170 mmSome measuring points have only very little space between ceilingand water surface. In such cases, for example in closed stormoverflow basins, horizontal mounting of the sensor is recommended.The radar impulses must be directed via a 45° reflector - for examplea stainless steel sheet - to the water surface.45°> 50 mm(1.97")Fig. 9: Horizontal mounting with a mounting strap of length 170 mm with reflectorprovided by the customerInformation:With this mounting arrangement, the reference plane mentioned inchapter "Technical data" no longer applies. There is an offset thatmust be taken into account for the adjustment. Note the distancemeasured at min. level with the reflector, for example 2.5 m. Enterthis value as min. adjustment/measuring range begin. Determine thedifference between the min. and max. level, for example 1 m. The distancefor the max. adjustment results from 2.5 m - 1 m = 1.5 m. Enterthis value as max. adjustment/measuring range end.380<strong>61</strong>-EN-121011<strong>VEGAPULS</strong> <strong>WL</strong> <strong>61</strong> • 4 … <strong>20</strong> <strong>mA</strong>/<strong>HART</strong> - <strong>two</strong>-<strong>wire</strong>15
