Level measurement with
automatic density correction
(with media changing in the
tank)
Level measurement with automatic density correction is possible in conjunction with a limit switch such as
Liquiphant and a PLC. The limit switch always switches at the same level. In the switch point, the signal
processing unit determines the corrected density from the pressure of the Deltapilot M currently measured and
the known distance between Deltapilot M and the limit switch. The signal processing unit then calculates the
level from the new density and the measured pressure of the Deltapilot M.

In the example given, two Deltapilot M devices (each with a gauge pressure sensor) are interconnected. The
pressure difference can thus be measured using two independent Deltapilot M devices.
Caution!
If using intrinsically safe devices, strict compliance with the rules for interconnecting intrinsically safe circuits
as stipulated in IEC60079-14 (proof of intrinsic safety) is mandatory.
