Chemical and petrochemical, pharmaceutical and food, fluid recycling, offshore, oil and gas, machine building and plant construction – there is hardly any sector of industry where floats cannot provide information on the current liquid level. More often, there is the question as to whether level measurement using the float principle still has a place, and how this can find applications in sterile process engineering.
The experience from numerous applications offers the user a wide range of method and process-specific solutions − in the field of sanitary applications, too − all built around a range of standard products. Last but not least as a result of the unique design and the large variety of materials, in spite of the strong competition by other methods, float measurement technology still asserts itself in the market.
- Floats can provide information on current liquid levels in most sectors of industry.
- The use of floats is particularly dependent on the physical and chemical process conditions − pressure, temperature, density and viscosity − of the medium.
- An advantage of float-based level measurement is that it is not influenced by moving surfaces, electrical conductivity, dielectric constants, foaming and boiling surfaces.
