5 WEKA is selling worldwide Visual Level Indicators VLI 50 %Cryogenic Components25 %Tank Level Indicators TLI 15 %Stainless Steel Valves10 %Overall revenues of WEKA represent an approx. 12 mio AU$10% account for stainless steel valves15% each account for cryogenic components and TLI systems60% account for magnetic level indicators.We are the „pros“ in magnetic level indicators which are our daily bread and butter . None of our competitors has such a high production percentage sharein magnetic level indicators.Taking into account the approx. 10 mio AU$ worth of MLI‘s manufactured at GEMS in Plainville, GEMS/WEKA is the single largest supplier to the MLI market.In addition we also are the only source manufacturing MLI‘s on both sides of the Altlantic.Total Revenues ~ 5 Mio. EUR(90% Export)

8 Our Vision Know-How, Quality, Flexibility To be the leader in level measurement of liquids with the float technologyTo be the leader in the cryogenic component marketTo grow sustainablyTo improve know-how and quality standards continuouslyTo maintain high flexibilityTo act responsible towards customers, environment and employees
12 Phyisical principle Function Based on the float principle and the principle of communicating vessels the liquid level inside the VLI is always the same as in the vessel to be monitored
13 Floats Forced level transmission Hermetically sealed floats For pressures up to 350barDensities > 0.3g/cm3Compact dimensionsLarge float choice for optimal selection of the indicator
14 Bar Magnet System Horizontal bar magnet AlNiCo magnet Horizontal magnet fieldHighest magnetic fluxLarge radial extensionLow weightSingle pole activation of accessories
15 Magnetic guiding tape system FunctionSimilar to a compass needle, the bar magnet inside the float always points to theintegrated magneticguide tape.
