1. WEKA Visual Level Indicator (VLI)

2. Location
WEKA is situated in Baeretswil, 25 km south east of Zurich and can be easily reached in half an hour by car or public transport.

3. Background WEKA was founded in 1940
Member of the ARCA Flow Group since 2001
Leading manufacturer of instruments for level measurement of liquids, cryogenic components and special valves
45 employees
More than 90 percent of the turnover is realized by exporting
Our strengths are: development, production and testing of tailor-made solutions
Instruments for level measurement (VLI and TLI) are sold through a world wide net of representatives
Cryogenic components and special valves are mostly sold directly to our world wide customer base

5. WEKA is selling worldwide
Visual Level Indicators VLI 50 %
Cryogenic Components
25 %
Tank Level Indicators TLI 15 %
Stainless Steel Valves
10 %
Overall revenues of WEKA represent an approx. 12 mio AU$
10% account for stainless steel valves
15% each account for cryogenic components and TLI systems
60% 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)

11. Visual Level Indicator (VLI = Visual Level Indicator)

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 350bar
Densities > 0.3g/cm3
Compact dimensions
Large float choice for optimal selection of the indicator

14. Bar Magnet System Horizontal bar magnet AlNiCo magnet
Horizontal magnet field
Highest magnetic flux
Large radial extension
Low weight
Single pole activation of accessories

15. Magnetic guiding tape system
Function
Similar to a compass needle, the bar magnet inside the float always points to the
integrated magnetic
guide tape.

16. Other Magnet Systems Magnet system Ring magnet Fe-Oxyd Magnet
Vertical orientation
Small radial extension
High Weight
Risk of double switching
Back-to-back Systems
Ring magnets
Fe-Oxyd magnets
Back-to-back orientation
Magnetisch bedenklich
Big radial extension
Very high weight
Long term stability in question
