UFM 800 W for pipelines

UFM 800 C for open channels

UFS 800 WMounting location and installation

Position the UFM 800 W in the pipeline such that the measuringtube 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 becompleted by KROHNE technicians.

Install UFC 500 F signal converter in the vicinity of the measuringpoint (UFS 800 W sensors).

Gas contentThe gas content in the process liquid must not exceed a maximumof 0.2% by volume at flowing conditions.

Please note:Even in liquids that are virtually gas-free, large quantities of gas mayform if the liquid is allowed to expand before reaching the measur-ing point, e.g. downstream of partially closed valves or small pumpoutlets.

Inlet run: 10 x BOutlet run: 5 x B(B = width of channel)

Sensors can be installed either from the inside or the outsideof the channel.

Sensors aligned by KROHNE technicians are precisely set usinglaser alignment.

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 fromall 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 connectionbetween 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.
