4.2 Installation safety precautions
FSS200 clamp-on sensors
22 Installation Manual, 08/2017, A5E36255466-AC
Prevent the device from overheating or materials becoming brittle due to UV exposure by
protecting it from direct sunlight. Make sure that the maximum permissible ambient
temperature is not exceeded. Refer to the information in Technical data (Page 81).
Installation in hazardous location
Risk of explosion in hazardous areas
Special requirements apply to the location and installation of the device. See Installation in
hazardous areas (Page 15).
Installation safety precautions
Special precautions must be taken when the flowmeter is mounted in applications with
working pressures/media that can be dangerous to people, surroundings, equipment or
others in case of pipe fracture.
● Take appropriate protective measures to avoid contact with surfaces with temperatures
above 70 °C (155 °F).
● Prevent severe external stresses and loads from acting on the device.
● Do not install the flowmeter in the vicinity of strong electromagnetic fields, for example
near motors, variable frequency drives, transformers etc.
Note
Material compatibility
Siemens can provide you with support concerning selection of sensors. However, you are
responisible for the selection of components. Siemens accepts no liability for faults or
failures resulting from incompatible materials.
Sensor installation parameters
The following parameters are required for a correct sensor installation, ensuring the best
possible flow measurement accuracy:
●
material, outer diameter, wall thickness, Liner material and thickness (if
applicable), pipe roughness, upstream and downstrream straight run (in pipe diameters).
●
Type of fluid, fluid sound speed (if known), process temperature, fluid
viscosity, positive flow direction.
