VEGA VEGASON 64 Foundation Fieldbus - Manual (Page 22)

If there are strong air currents in the vessel, e.g. due to strong winds in
outdoor installations or air turbulence, e.g. by cyclone extraction you
should mount VEGASON 64 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.
