Level visualization and control in closed and/or buried metal tanks.

The MAGTOP 400 and 410 are devices designed to indicate the liquid level in a tank in real time. A float, attached to a rod, causes a pointer to move up and down in a tube located above the tank, as the level rises or falls. Thanks to its two-color magnetic flaps that pivot as the pointer passes through the measuring column, it provides a clear and accurate visual reading. Its mechanical robustness allows it to be used with liquids such as hot water or oils subject to relatively high temperatures or pressures.

Operating conditions
This model is suitable for pressures up to 16 bar and maximum temperatures of 300 °C. For use beyond these limits, it is necessary to use the MAGTOP D model (see technical data sheet 560-03).

Assembly and modularity
The indicator is mounted on the tank using a flange connection. To simplify assembly or meet transport requirements, the MAGTOP 410 can be manufactured in two parts.

Manufacturing drawing
Each MAGTOP is manufactured according to a drawing that must be approved prior to production. For each MAGTOP, it is necessary to provide the operating conditions and connection specifications.

• Fluid nature
• Density (kg/m3)
• Pressure (bar)
• Temperature (°C)
• Connection size (Nominal Diameter)
• Immersion height (mm)
