Installation conditions for density measurement

Conditions
• If possible, density should be measured on vertical pipes with forward flow from bottom
to top.
• If only horizontal pipes are accessible, the path of the beam should also be arranged
horizontally to minimize the influence of air bubbles and deposits.
• The Endress+Hauser clamping device or an equivalent clamping device should be used to
fasten the source container and the Gammapilot FMG50 to the measuring pipe.
The clamping device itself must be installed in such a way as to withstand the weight of
the source container and the Gammapilot FMG50 under all anticipated 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 in the case of pumps.
Measuring system arrangement
The arrangement of the source container and the Gammapilot FMG50 depends on the
pipe diameter (or the radiated length) and the density measuring range. These two
parameters determine the measuring effect (relative change in the pulse rate). The longer
the radiated length, the greater the measuring effect. Therefore, it is advisable to use
diagonal irradiation or a measurement section for small pipe diameters.
To select the measuring system arrangement please contact your Endress+Hauser sales
organization or use the Applicator™
