2.4 Measuring Configuration
Measuring systems for density, concentration and mass flow measurements typically
comprise the following components:
Radioactive source (a)
Shielding container (b)
Detector (c)
Evaluation unit LB 444 (d)
Mounting device (e)
Connection cable (f)
Resistance thermometer Pt 100 (option) (g)
Cooling jacket for detector (option)
The detector’s power supply and the measuring signal (pulses) are transmitted via the
cable connected between detector and evaluation unit.
Figure 2: Measuring system mounted on a pipeline
Different configurations and mounting devices may be required, depending on the meas-
uring tasks, the condition of the product being measured and the containers.
Figure 2 shows a basic setup in a pipeline with Pt 100 resistance thermometer and a 90°
mounting device for density, concentration and mass flow measurement.
45° and 30° mounting devices are available to extend the measuring path.
U or S-shaped measuring paths may be used for smaller pipeline diameters. Measure-
ments in containers are also possible (see 5.2.2).
