StandardLine for Proven Level Measurement up to 400°C
The StandardLine offers magnetic level indicators for pressures up to 50 bar and temperatures up to 400°C as proven standard. Whether water, heating oil, toxic, or explosion-hazardous media (ATEX/IECEx) – this versatile product line covers a wide application spectrum.
Explore the proven solutions of the StandardLine for your reliable level measurement.
StandardLine

Three Pressure Levels for Maximum Flexibility
The WEKA rod magnet principle enables a variety of float types for diverse parameters. The StandardLine includes three pressure levels (6/28/50 bar) with EN and ANSI connections as standard – whether flanges, threads, or welding ends. Manufactured according to European PED or American ANSI/ASME standards.
The proven standard material 316/316L (1.4401/1.4404/1.4435/1.4436) ensures high resistance with optimal magnetic compatibility. Simple pressure-temperature diagrams allow precise determination of the basic type including connections.
Magnetic switches and transmitters for continuous signal transmission extend functionality for demanding control system integration.
The complete range of 2- and 3-wire devices is available in normal or Ex variants. Additional tests such as X-ray or dye penetrant testing as well as surface finishing through pickling or passivation are possible as standard.
