Sample Point - Consort R305 Mode D'emploi

Before the exact location of the electrodes is finalised, it is worthwhile to carry
out a measuring profile of the process stream to ensure that the required homo-
geneity is being achieved. As a general rule the electrodes should protrude into
the process stream by one-third of the pipe width and be positioned so as to avoid
gas pockets or sediments.
Generally the measuring electrodes are inserted into the flow with the sample
pick-up facing downstream in order to reduce the risk of blockage by suspended
material.
All sensors are usually positioned vertically at a suitable point downstream of the
dosing point, where the measurements are stable and reliable. The response of
the dosing system will be affected by the time required to disperse the reagents
and their arrival at the measuring point.
