Operation Manual

6. Installation
ATTENTION!
Wrong measurement is possible, if the sensor is not
installed correctly.
Careful attention must be paid to the design of the inlet and outlet
section. Obstructions can cause counter-flow turbulence as well as
turbulence in the direction of the flow.
The sensor is for indoor use only! At an outdoor installation, the
sensor must be protected from solar radiation and rain.
