Product catalog summary
Overview of WEKA Tank Level Instruments (TLI)
WEKA TLIs are designed to complement WEKA Visual Level Indicators (VLIs) by providing reliable tank level measurements where bypass installations are not feasible. These instruments are directly mounted on tanks and offer a dependable signal output for remote indicators or control systems. They are versatile, with various configurations available to meet diverse tank measurement needs, including installations at the tank bottom.
Float Technology
WEKA TLIs utilize float technology, which is highly reliable and accurate for liquid level sensing. This technology offers several advantages:
  • Floats track the actual liquid surface, unlike indirect methods such as pressure sensing.
  • They function effectively in tanks with curved walls or irregular shapes.
  • Floats can monitor liquid interface levels between two liquids with different densities, overcoming issues like foam and waves that affect other sensors.
  • They provide accurate and repeatable measurements without being influenced by pressure or temperature changes.
Technical Specifications
Various models of WEKA TLIs are available, each with specific technical data:
  • Type XM-/XT-825E: 2.5 mm resolution, 1.5 m max length, made of brass or 316/316L.
  • Type XM-/XT-800E: 5 mm resolution, 3 m max length, made of brass or 316/316L.
  • Type XT-800R: 5 mm resolution, 3 m max length, made of 316/316L.
  • Type XM-/XT-36000E: 12.7 mm resolution, 5 m per sensor, made of stainless steel.
  • Type XM-/XT-140000E: 5 mm resolution, 5 m per sensor, made of stainless steel.
Operating Principle
WEKA TLIs operate using a voltage divider principle. The sensors are vertically mounted and connected to a remote receiver. As the float moves with the liquid level, it closes reed switches in sequence, altering the voltage divider's output. This electronic system requires minimal maintenance due to its self-cleaning float design.
Conformance and Applications
WEKA TLIs conform to European Directives 97/23/EC (PED) and 94/9/EC (ATEX) for explosion protection. They are suitable for various applications, including chemical processing, railways, and automotive industries. Custom solutions are available for specific requirements, such as integrated temperature sensors or special mounting elements.
Company Background
WEKA AG, part of the ARCA Flow Group, has a long history of innovation in level measurement and valve technology. The company is based in Switzerland and offers a range of products, including visual level indicators, cryogenic components, and stainless steel valves.

Modular Design Technical Data Tube size Special features ● WEKA TLI: Tank Level Instruments WEKA TLIs optimally complement the range of WEKA VLIs (Visual Level Indicators). Wherever physical conditions prevent a bypass type level measuring installation, a WEKA TLI product would be the preferred alternative. The TLI sensor is installed directly on the tank, and provides a reliable level measurement signal output that can be fed to a remote indicator or control system. A wide choice of standard accessories and fittings allow TLI sensors to be configured to meet virtually any tank level measurement...
