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
