OVERFILL SAFE & OVERFILL PROOF
Eclipse 7xR, 7xM, 7xT and 7xN coaxial type GWR probes are
“overfill safe” in operation and “Overfill proof” certified.
Overfill safe means that the unit is capable of measuring up
to the process connection. “Non overfill safe” probes often use
software algorithms to ignore level readings in the blocking
distance or transition zone. When level rises in this zone, non-
overfill safe may consider the end of probe reflection as to
the real level and may report an empty vessel instead of a full
vessel.
Overfill proof protection (such as WHG or VLAREM) certifies
reliable operation when the transmitter is used as overfill alarm
but assumes that the installation is designed in such way that
the vessel/ cage cannot overfill.
