Basic Advanced
Measuring system
Measuring principle Bypass level indicator (principle of communicating tubes). A float in
the measuring chamber (Ø42 mm / 1.7¨) is magnetically-coupled to a
mechanical level indicator.
Application range Level indication of liquids for
low-pressure applications and in
storage tanks
Level indication of liquids in
applications up to 40 barg /
580 psig
Measured value Measured value Measured value Measured value
Primary measured value Level of the float magnets in the measuring chamber
Secondary measured value Level and volume of the liquid in the measuring chamber
