7 Sizing guide Ordering guide UFM 800 for pipelines UFS 800 W Mounting location and installation Position the in the pipeline such that the measuring tube is completely filled with the process liquid at all times, even at zero flow velocity. Make sure that the measuring beam is approximately horizontal. Installation and alignment of FS 800 W ultrasonic sensors can be completed by KROHNE technicians. Install UFC 500 F signal converter in the vicinity of the measuring point (UFS 800 W sensors). Gas content The gas content in the process liquid must not exceed a maximum of 0.2% by volume at flowing conditions. Please note: Even in liquids that are virtually gas-free, large quantities of gas may form if the liquid is allowed to expand before reaching the measuring point, e.g. downstream of partially closed valves or small pump outlets.

8 UFM 800 Electrical connection, UFC 500 F (M 4.1) Power supply, power consumption and load rating of outputs: see Technical data (page 5) Current and pulse outputs (I + P) are galvanically isolated from all input and output circuits, when used in passive mode. Use the supplied signal cables (coaxial), length 5 m /16 ft, max. length 50 m /160 ft (optional), for the electrical connection between sensors and signal converter. Ambient temperature must be from 25 to +60 C ( 13 to +140 F), therefore do not cover signal converter with heat-insulating materials, and do not expose to strong sunlight or other heat sources. Avoid intensive vibration.
