P

 

PACTware

™ 

Software that operates and configures field devices from a remote

 

workstation. It is not necessary to use fieldbus software or programs developed 

by the manufacturer.

 

 

 

R

 

Radar reflection 

Signal reflected from the surface of the tank contents.

 

 

 

S

 

Signal converter 

A set of electronic components in the device that send the measurement

 

signal through some signal filters. They identify and measure the level of the tank 

contents.

 

 

 

T

 

TBF 

Tank Bottom Following (TBF) mode is an alternative measurement mode. It allows 

the device to measure tank contents with very low dielectric constants. TBF 

mode uses the reflection of the tank bottom to indirectly measure the level of 

the tank contents.

 

 

 

U

 

Ullage volume 

Unfilled volume. See the diagrams at the end of this section.

 

 

 

V

 

Volume 

Total volume of tank contents.
