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 measuring path for small
pipe diameters.
To select the measuring system arrangement please contact the Endress+Hauser sales organization
or use the Applicator™configuration software.
