Operating and Maintenance Instructions, Intrinsically Safe Triple Function Gauging Tape for Open Applications Liquid Measure ff Ullage, Oil/Water and Temperature MODEL D-2401-2
Year: 2018 Language: english Author: MMC Genre: Manual Format: PDF Quality: eBook Pages count: 30 Description: 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 a 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.

Description: 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 a 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.
