Visual Level Display with Precise Measuring Scales
Experience intuitive level reading with WEKA indicator rails and measuring scales. The red-silver color-contrasted indicator flags respond to the float's magnetic field and provide a causal, interpretation-free visual reading. Combined with precise measuring scales, individual values such as percentages, volume or liters can be read directly.
Indicator Rails / Measuring Scales

Proven Magnetic Guide Band System for Precise Display
Like a compass needle, the float in the magnetic level gauge always aligns with the patented magnetic guide band integrated in the indicator rail. As the float follows the fill level, a magnetic field force is transmitted outward, which is used to flip the color-coded indicator flags.
The red-silver color-contrasted flag display is clearly readable even over long distances. In combination with measuring scales made of Alu-Dibond or stainless steel, individual values can be read directly – available in metric, imperial or customer-specific divisions. Thanks to robust construction, the system functions reliably even under demanding operating conditions.
