Installation location
The sender/receiver units can be installed on vertical, horizontal, or inclined ducts or pipe-
lines. In vertical ducts, a minimum distance from the duct outlet (approx. 30 m) must be ob-
served in order to prevent noise disturbance caused by rain drops on the probe head.
The mounting location for the device components must be free of vibration.
If a purge-air unit is required, it must be mounted at a location that allows the intake of clean
air. The intake temperature must match the values specified in the technical data.
The mounting location should be equipped with power connections and permanent lighting.
Platform
The sender/receiver units must be easily accessible for installation and maintenance. If
necessary, provide a suitably wide platform secured by a handrail.
Warning
The plant operator is responsible for ensuring that the applicable accident prevention and
occupational health and safety regulations are observed.
In vertical ducts, the installation angle should be selected as a function of the duct diameter
so that only one platform is necessary. An additional basic platform and/or sealable ope-
ning in the platform with a basket guard can be helpful (see Fig. 3.2).
Ensure that sufficient clearance is provided for installing and removing the sender/receiver
units.
