All Level Measurement Products
WEKA SmartLine in focus

NEW: WEKA presents its product lines in profile

No news in the classical sense, but still worth a note. In the next few weeks, we will take turns at this point to present our product lines from the two business areas of valves and cryogenic components as well as level measurement technology in more detail.

In doing so, we will focus on the most important features and characteristics in order to provide you with a well-founded overview in a nutshell.

Today we will start with our "Smart Line 50" a bypass level indicator (VLI) from the field of level measurement technology.

Fields of application

Did you know that our Smart Line 50 is predominantly used in the chemical and pharmaceutical industries, explosion-proof plants, mechanical and plant engineering, water management and shipbuilding?

Task and function

In the portfolio of all VLI this is the product line, for universal use in simple applications. The reliable visualization and detection of levels of liquid media in containers, whose accessibility is not given by pressure, temperature or for other reasons. 

Functional principle

In the bypass chamber, a float moves on the liquid surface with a magnet that actuates an indicator rail on the outside or controls electrical accessories.

Special suitability in the field of application

Made possible by the WEKA magnet system, the smallest size on the market has been created. The float chamber with an outer diameter of 33.7 mm (1'') saves material, weight and therefore transport costs.

With a maximum operating pressure of 50 bar (5 MPa), no compromises were necessary in the low-pressure range. However, the small size is responsible for the restriction in the max. viscosity of the medium: instead of 600 cSt, the SmartLine can still be used up to 150 cSt. The temperature range was also limited to 250°C in favor of the solenoid system. 

The product line is aimed at uncomplicated level detection of water and oil, nevertheless material verification (certificates / PMI) or other non-destructive test methods (excl. RT) are available.

Otherwise, the full variance of all VLI, also in the Ex-area, is available. From length and flange connections to the full range of accessories (indicator rails, magnetic switches, transducers, etc.).

Variable features within the product line

  • Length / connection dimension
  • Float chamber diameter
  • Version process connections
  • Version service connections (-A / -B / -K / -O)
  • Display rail
  • Accessories (number & design of magnetic switches / design of transducers / other accessories)

Available versions

SmartLine 50 - for universal use up to 50 bar and 250°C.

The version with integrated valves (34110) saves space and avoids additional effort and connection points.

Tip: With the material variant in CuNi (copper/nickel alloy) we can guarantee absolute corrosion resistance in seawater (shipbuilding, submarines, seawater desalination plants).

Available accessories

In addition to the different versions of the indicator rails, the extension of point limit switches by magnetic switches or the continuous signal acquisition by transducers is possible.

The accessories are also adapted to the respective requirements regarding application parameters, certificates and approvals.

Available spare parts

Among the product's advantages are its durability, designed to last for decades, and low maintenance requirements. For example, there are virtually no wear parts - yet floats and seals can be reordered. Should a defect occur in the indicator rail or electrical accessories, the parts can be replaced without any problems.

Tip: Give your contact person the serial number from the type plate. In our archive all orders of the last 50 years are documented, so that we can offer the optimal replacement.

Current market approvals

In addition to the usual requirements for pressure vessels by the European Union (CE) and the Eurasian Union (EAC), applications in European explosion protection (ATEX) and international explosion protection (IECEx) as well as shipbuilding can also be served.

Current certificates

  • Declarations of conformity / certificates according to CE and EAC
  • Declarations of conformity / certificates according to ATEX and IECEx
  • Shipbuilding certificates according to BV, DNV, RS and RINA

Additional useful information about the product line

Materials and connections according to ANSI/ASME standards and welding approvals according to ASME are available for international use.
