– for smooth metallic walls: > 50 mm (2 in)
– for plastic walls: > 300 mm (12 in) to metallic parts outside the vessel
– for concrete walls: > 500 mm (20 in), otherwise the available measuring range may be
reduced.
• Distance (B) between rod or rope probe and internal fittings in the vessel: >
300 mm (12 in)
• When using more than one Levelflex:
Minimum distance between the sensor axes: 100 mm (3.94 in)
• Distance (C) from end of probe to bottom of the vessel:
– Rope probe: > 150 mm (6 in)
– Rod probe: > 10 mm (0.4 in)
– Coax probe: > 10 mm (0.4 in)
For coax probes the distance to the wall and to internal fittings is arbitrary.
