3.2.4 Installation conditions for density and concentration
measurement
Conditions
• If possible, density and concentration should be measured at vertical pipes with a feed
direction from bottom to top.
• If only horizontal pipes are accessible, the path of the ray should also be arranged
horizontally to reduce the influence of air bubbles and sediments.
• The Hauser clamping device (

ä
81, "Accessories") or an equivalent clamping
device should be used for fastening the radiation source container and the Gammapilot M
to the measuring tube.
The clamping device itself must be installed in a way such that it can withstand the weight
of the source container

and the Gammapilot M
4)
under all operating conditions.
• The sample point may not be further than 20 m (66 ft) from the measuring point.
• The distance of the density measurement to pipe bends is  3 x pipe diameter and  10 x
pipe diameter for pumps.
Configuration of the measuring system
The configuration of the source container and the Gammapilot M depends on the pipe
diameter (or the length of the irradiated measuring path respectively) and the measuring
range. These two parameters determine the measuring effect (relative change of the pulse
rate). The measuring effect increases with the length of the radiation path through the
medium. Therefore, diagonal irradiation or the use of a measurement section is necessary
for small pipe diameters.
For the configuration of the measuring system please contact your Hauser sales
organization or use the "Applicator"

configuration software.

NOTICE
General
‣
To increase the accuracy for density measurements, the use of a collimator is
recommended. The collimator screens the detector against environmental radiation.
‣
When planning, the total weight of the measuring system must be taken into
consideration.
‣
The Gammapilot M should be given additional support to secure it against falling or
prevent damage to the connecting cable.
‣
A clamping device and a measurement section are available as accessories (

81,
"Accessories").
3) The weights of the source containers are specified in TI00445F/00/EN (FQG60), TI00435F/00/EN (FQG61, FQG62), TI00446F/00/EN (FQG63)
or TI00346F/00/EN (QG2000).
4) The weights of the various versions of the Gammapilot M are summarized in the section "Dimensions, weight".
5) The "Applicator"  is available from your Hauser sales organization.
