KROHNE OPTISOUND 3050C 4wire EN - Manual (Page 21)

If there are strong air currents in the vessel, e.g. due to strong
winds in outdoor installations, or because of air turbulence, e.
g. through cyclone exhausting, you should mount OPTI-
SOUND 3050 C in a standpipe or use a different measuring
principle, e.g. radar or guided radar (TDR).
Strong heat fluctuations, e.g. caused by the sun, can cause
measurement errors. In this case, you should use a sun shield.
