2.4 General safety guidelines 

ULM-3D level transmitter meets all modern requirements and safety standards. 
The operating frequency of level transmitter is about 125 GHz.  The radiation pow-
er does not exceed 8 MW, which is significantly lower than the maximum permissi-
ble values. The level transmitter is completely safe for humans and animals. 
The device may be operated only in good working order to avoid occupational acci-
dents. 
ULM-3D level transmitter without an explosion protection label may be used only 
in an explosion-proof zone. 
 

2.5

 

 Environmental safety 

Compliance with the recommendations provided in sections "Packaging, transporta-
tion, and storage" and "Disposal" contributes to environmental protection.
