NOTICE TO ALL EQUIPMENT USERS
The triple functions of this sensor are to detect cargo surface level,
Ullage
, the
Interface
between two
immiscible products such as oil and water, and cargo
Temperature
.
The normal order of the gauging device, response to the products “Ullage level”, is a steady horn tone.
The normal response to an “Interface level”, (i.e., between a non-conducting and an electrically
conducting product such as a petroleum product and water, is a “
steady
” tone changing to a “
beeping
”
tone at the interface level.
A special note to our chemical customers, is the fact that some chemical cargoes may be
inherently conductive.
Therefore, at the surface of a conductive product’s Ullage level, a “
beeping
” tone will be the normal
response.
As a further note to the above, the change in detection of a non-conductive product Ullage level as a
steady tone to that of a conductive product’s ullage “beeping” tone, it is not to conclude that the sensor
is malfunctioning.
