1.1.2 7828 MEASUREMENTS
The 7828 measures the following fluid properties:
• =
Line Density (Measured in kg/m 3 , g/cc, lb/gal, or lb/ft
3
)
•
=
Temperature (Measured in °C or °F )
From these properties, the following are calculated:
•
=
API base density at 15°C, 1.013bar; or at 60°F, 14.5psi
•
=
Base density by the Solartron matrix referral method
• =
°API
•
=
S.G.
•
=
Special function calculations such as °Brix, °Baume, °Twaddle, % solids, etc.
1.1.3 WHAT IS IT USED FOR?
The 7828 Transmitter is ideally suited to applications where continuous real time
measurement of density is required, for example in process control where density is the
primary control parameter for the end product, or is an indicator of some other quality
control parameter such as % solids or % concentration.
Some examples are:
•
=
Blending
•
=
Mixing
•
=
Evaporator control
•
=
End point detection in batch reactions
• =
Interface detection in continuous separators
•
=
Interface detection in multi-product pipelines
Typical industries include:
•
=
Oil and petrochemical
•
=
Brewing
•
=
Food
•
=
Pharmaceutical
•
=
Minerals processing (clays, carbonates, silicates, etc.
