Top-of-Tank Level Indicators (ToT VLI) for Tank Top Mounting

Top-of-tank level indicators offer all advantages of magnetic level indicators with space-saving mounting directly on the tank. Instead of lateral installation, the ToT VLI is mounted on top of the tank deck, with the magnetic carrier above the tank deck connected to the float through a connecting tube.

WEKA Rod Magnet Principle for Compact Solutions
The proven WEKA functional principle with horizontal rod magnet ensures clear and reliable control of display rail, switches, and transmitters even with top-of-tank level indicators. The float detects the level directly and inevitably – the energy-free display operates without further calculations even during power outages.

Wide Application Range
Like bypass level indicators, ToT VLI offer maximum flexibility in operating conditions and cover the complete parameter range.

Material Diversity
From standard materials like 316/316L to special alloys (Inconel, Hastelloy, Titanium) and plastics (PVDF, PTFE). All non-magnetic materials are principally applicable.

Safe Readability
The red-silver color-contrasted flag display is readable over large distances while hazardous media remain safely enclosed in the pressure-resistant float chamber.
