Base station. In real life, there may be no LOS condition. However, the Sigfox sensor still communicate with Base
station, but the distance will be reduced significantly.
Consider to use the isolation valve 1/2" or 1/4" to isolate the media and the sensor during maintenance;
Fully closing the isolation valve during installation and maintenance the sensor;
Fully open the isolation valve during normal operation;
There are two ways of process mounting as below.
The total weight of the sensor MUST be within the permitted load of the pipe to be installed;
Consider to build the support for the pipe if the sensor weight is larger than the permit;
Below picture shown without the isolation valve, but we highly recommend to use isolation valve.
ATTENTION:
DO NOT
install the Sigfox sensor or its antenna inside a completed metallic box or housing, because RF signal
can not pass through metallic wall. The housing is made from Non-metallic materials like plastic, glass, wood,
leather, concrete, cement…is acceptable.
