    The reference plane for the measuring range is the lower edge of the Reference plane for measuring range transducer. Make sure that a minimum distance from the reference plane - the so-called dead zone, in which measurement is not possible - is OPTISOUND 3020 C • Profibus PA...
  • Page 11 C. Low pressure or vacuum does, however, damp the ultrasonic pulses. This influences the measuring result, particularly if the level is very low. With pressures under -0.2 bar (-20 kPa) you should use a different measuring principle, e.g. radar or guided radar (TDR). OPTISOUND 3020 C • Profibus PA...

    4 Mounting Mounting instructions Screwing in Screw OPTISOUND 3020 C into the mounting socket with an ap- propriate spanner applied to the hexagon of the process fitting. Max. torque see chapter "Technical data". Warning: The housing must not be used to screw the instrument in! Applying tightening force can damage internal parts of the housing.
  • Page 13 Fig. 7: Recommended socket mounting If the reflective properties of the medium are good, you can mount OPTISOUND 3020 C on sockets which are higher than the length of the transducer. You will find recommended values for socket heights in the following illustration.
