When choosing a site for the installation of the sensor the following precautions should be observed:

It is advisable to set up the sensor in quiet surroundings, as high acoustic noise levels will impair the measurement of small drops. Signals caused by acoustic noise will be suppressed by the instrument, but drop signals not exceeding the level of the noise signal will be suppressed together with the noise signal. Drop signals exceeding the noise signal will be measured with full accuracy. The presence of acoustic noise therefore may cause a reduction in the number of small drops measured.

A similar effect is caused by strong winds producing turbulence at the edges of the sensor. Mounting the sensor with its top even with the surroundings will reduce this effect.
