Fast, accurate control
for semi-automatic drum filling systems.
Two speed net weight filling control for top
fill or substance fill drum fillers
The FWC-788 Controller offers full electronic control
for the standard Fuller filling units. The controller utilizes
a Cardinal 788 instrument enclosed in a NEMA-4, painted enclosure
with a pneumatic interface for operating the lance assemblies.
The 788 offers multiple product filling for either foaming
or non-foaming products with many features and safety interlocks
included.
