2. SYSTEM DESCRIPTION
2.1 Use and Function
The radiometric density measuring system can be used to measure the density
of
• liquids
• suspensions
• pulps and
• bulk goods.
The measurement can made directly in-line or in a tank or container. Pressure
and viscosity fluctuations or the flow rate of the product does not affect meas-
urement accuracy.
Special instrument configurations and calculations allow the measuring system
to be tailored to the local needs and conditions of the product being measured:
a) Instrument configuration (Operating modes)
• Density measurement without temperature compensation (TC)
• Density measurement with temperature compensation via Pt 100
• Density measurement with temperature compensation via current input
• Suspension measurement with any carrier liquid
Solids density and liquid density are known
With or without TC
• Suspension measurement with water as carrier liquid
- Solids density is known
- with water temperature compensation
♦ the density of the water and
♦ the solids concentration
are used for temperature compensation
• Mass flow measurement without TC
• Mass flow measurement with TC via Pt 100
b) Special configuration
• Back-scatter measurement
c) Selection of measurement mode
• Continuous measurement
• Discontinuous measurement
- Batch operation via keyboard (press <
run
> button)
- Batch operation via digital input
