Precise Density Measurement for Reliable Level Indication
Experience highest measurement accuracy with WEKA floats operating on the proven rod magnet principle. Each float is precisely calibrated to the density of your measurement liquid, ensuring that the integrated rod magnet is positioned exactly at the liquid surface level. The innovative design guarantees reliable function even under the most extreme operating conditions.

Innovative Rod Magnet Principle for Highest Precision
Each WEKA float is precisely calibrated to the density of your measurement liquid, ensuring that the integrated rod magnet is positioned exactly at the liquid surface level. The magnetic field acts with the north pole on the indicator flags and with the south pole on optional accessories such as magnetic switches or level transmitters.
The low weight of the rod magnet principle enables lightweight construction with maximum radial clearance to the standpipe – ideal for contaminated or viscous media. Selected magnetic materials ensure reliable function even at extreme operating temperatures up to 400°C.
| Type | Max. Pressure | Density | Diameter |
| Cylinder Floats | ≥60 bar/ open | ≥1.2 | 26/42/47mm |
