If I understand correctly, the description is of a vessel containing two liquid phases of oil over water. The interface between the phases is kept below the top of the vertical weir at all times. As oil accumulates, it overflows the weir to a segregated part of the vessel. The top of the oil layer will be essentially at the weir height. The interface is the bottom of the oil layer so no water flows over the weir -- only oil.

Hi,

 

Because at HHIL there is the risk of water overflow from the weir, hence stopping the incoming flow to the separator could be reasonable...what's your problem?

Of course, referring to the picture there is no indication for trip at HHIL but it might be just alarm for operator intervention...please recheck and come back for clarification...
