Fig. 5: Installation possibilities - Density measurement or concentration meas-

urement

1a Radial raditiona - vertical mounting

1b Axial radiation - Horizontal mounting or when the lead cover is used as

protection against ambient radiation

2 Inclined radiation for extention of the radiated length (L)

3 Extension of the radiated length (L) by adding a tube angle piece as meas-

uring distance

4 Integrated lead cover as protection against ambient radiation - the instru-

ment is hence shielded laterally

Withdensitymeasurement,theradiationdierencewithdiering

density is very low. Especially with small tube diameters, the change

is negligible.

Therefore it is important to shield from interfering X-ray radiation. To

protect the instrument against X-ray radiation, it can be be equipped
