5 Recommendation Site Selection / Standard Installation
Depending on the wind velocity, a certain amount of the precipitation particles are blown away over
the deposit area. Therefore, an installation in a completely open area as well as at the direct lee-
side of an object is to be avoided. Gardens e.g., where hedgerows or similar objects offer
protection against the wind, are more suitable.
The World Meteorological Organization recommends that precipitation gauges be installed at a
distance which is at least four times as high as the next higher object. If this is not possible, it is to
be observed that an elevation angle of
≤
45° towards the surrounding plants, buildings etc. is
adhered to.
The precipitation gauge is to be installed in such a way that the collection area is horizontal and is
situated 1 m above ground. If snowfall is to be expected regularly within the area of the measuring
instrument this distance should be increased respectively.
Attention:
Precipitation gauges are to be installed in a way that ensures a
vibrationless operation.
6 Installation
Attention:
- The electrical connection is to be carried out by experts only.
- Please open the instrument only with dry ambient conditions.
- Do not damage the exposed electronics!
6.1 Mechanical Mounting
Attention:
-
The included tipping bucket must be operated only
with this precipitation transmitter.
- Please don’t touch the inner surfaces of the tipping bucket.
- The drain pins of the tipping bucket must not be
deformed.
Remark:
The combination filter/cram (14/15) in the collecting funnel is to be removed in
winter operation with snowfall
