INTERFACE
E3 Modulevel is capable of tracking the interface level
of two immiscible liquids with different densities. Each
unit is custom-made with a displacer specially designed
for the user’s application. This allows it to detect the
position of a clean interface or an emulsion layer and
convert it into a stable 4 –20 mA signal. Contact the factory
for assistance in specifying an E3 for interface service.
Note that for proper interface detection, the entire
displacer must always be immersed in liquid.
DENSITY
Yet another capability of E3 Modulevel is to track the
changing density of a liquid over a known density range
and convert that into a stable 4–20 mA output signal.
As the density of the liquid changes, so does the mass
of the liquid displaced by the specially designed dis-
placer. The resulting change in buoyancy force on the
displacer causes the movement of the LVDT core nec-
essary to convert the density change to the 4–20 mA
signal.
PACTware^™ P C S O F T W A R E
PACTware PC software and the Field Device Tool (FDT)
standard take level measurement to a new degree of
setup efficiency and user-friendliness. PACTware adds a
graphical software interface for increased ease of use.
Simply connect your PC through a serial interface to the
HART loop and all functionality can be accessed con-
veniently, and safely. Refer to Magnetrol PACTware
bulletins 59-101 & 59-601 for more information.
