Level measurement of liquids at high pressures

Level measurement of liquids, even at high pressures using the displacement principle

Modular assembly, replacement or retrofit without interruption of the process  
Pressure-tight separation of measuring and display parts  
Interface detection possible  
Displacement rod available 0.3 - 6 m (1 - 20 ft) 
 Resistant to high pressures ≤ 400 bar (5800 psig) and high temperature ≤ 400°C (752°F)  
Current output 4...20 mA and/or max.
2 limit switches

Application range
The level indicator can be used for various liquids. This device is suitable for extreme operating conditions. 
Temperatures '60 - +400°C ('76 - +752°F)  
Pressure Up to 400 bar (5800 psig)

If the display cannot be installed from above, e.g. there is an agitator in the vessel, it is possible to install it lateral in a special reference chamber. In both cases it is important to note that the non-measurable depth is 340 mm because of the spring mounting.

With special versions it is possible to measure the interface between two immiscible liquids of different densities. The displacer must be covered completely with liquid. The difference in density should be min. 100 g/l.

Typical products are: 
Water, aqueous liquids  
Acids/alkalis  
Organic and inorganic solvents  
All kind of pure liquids
