4 Mounting Fig. 2: Measures against moisture ingress Do not hold the VF-90 on the vibrating element. Especially with Transport Do not hold VEGAWAVE 61 on the vibrating element. Especially with the VF-90 flange and tube versions, the sensor can be damaged by the weight of the instrument. Remove the protective cover just before mounting.

Inflowing medium If VEGAWAVE 61 is mounted in the filling stream, unwanted false the VF-90 measurement signals can be generated. For this reason, mount the VF-90 at a position in the vessel where no disturbances, e.g. VEGAWAVE 61 at a position in the vessel where no disturbances, e.g. the VF-90 from filling openings, agitators, etc., can occur.
