Level metering device working on the guided microwave principle, comprising a single-wire line and specific connection piece, and connection piece for a level metering device of this type

摘要

The invention relates to a connection piece (20), comprising an upper connection piece part (21) and a connection piece wall (22) disposed below said upper connection piece part (21) and having a connection piece wall height (h). In said upper connection piece part (21), a level metering device (10) working on the guided microwave principle and comprising a single electric line (40) can be mounted. Connection piece (20) further comprises at least one electrical conductor (30a, 30b, 30c, 30d, 30e, 30f) spaced apart at a distance (a, a′) from the single electric line (40) of the level metering device (10) to be mounted on the upper connection piece part (21) and extending from the upper connection piece part (21) up to at least the 0.25-fold, and maximally up to the 2.5-fold of the connection piece wall height (h). By arranging at least one electrical conductor (30a, 30b, 30c, 30d, 30e, 30f) in said connection piece (20), previous interfering influences caused by connection piece (20) during a filling level measurement are reduced. The invention further relates to a combination of a level metering device comprising a single-wire line, an attachment means and at least one additional electrical conductor having a limited length.
