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.
Measurements can be carried out directly in a product line or in a container. They are not
affected by pressure and viscosity fluctuations or the flow rate of the product.
Special instrument configurations and calculations allow you to adapt the density meas-
uring system to the local situation and the conditions of the product being measured.
2.2 Instrument Configuration (Operating Modes)
• Density measurement without temperature compensation (TC)
• Density measurement with temperature compensation
− via Pt 100 or
− via current input
• Suspension measurement with any carrier liquid
− Solid density and liquid density are known
− with or without TC
• Suspension measurement with water as carrier liquid
− Solid density is known
− with water temperature compensation the density of the water and the
solids concentration are taken into account for temperature compensa-
tion
• Mass flow measurement without TC (in connection with a volume flow meter)
• Mass flow measurement with TC via Pt 100 (in connection with a volume flow
meter)
• Backscatter measurement (density measurement in containers where no instal-
lations are possible)
• Measurement modes
• continuous measurement
• discontinuous measurement
− Batch operation via keyboard (press <run> button)
− Batch operation via digital input
