By turning the instrument in the connection flange or mounting boss, the polarisation can be used to reduce the effects of false echoes. The position of the polarisation is marked on the process fitting of the instrument.

- Page 20 When using a swivelling holder, keep in mind that the distance between antenna and socket gets smaller as the inclination of the sensor increases. Additional false reflections may be generated which can influence the measuring result at close range. VEGAPULS SR 68 • 4 … 20 mA/HART two-wire...

It can be easily checked with a suitable level or water leve on the sensor. The following chart specifies the distance "a" between installation position and vessel centre dependent on the measuring distance for inclination angles of 2°...
- Page 25 If there are agitators in the vessel, a false signal suppression should be carried out with the agitators in motion. This ensures that the interfering reflections from the agitators are saved with the blades in different positions. VEGAPULS SR 68 • 4 … 20 mA/HART two-wire...
- Page 26 Fig. 20: Radar sensors on traverse crane Information: Keep in mind that for these applications, the sensors are designed for relatively slow level changes. When using VEGAPULS SR 68 on a movable bracket, the max. measuring rate must be observed (see chapter "Technical data").
