ABSTRACT:
Liquid is removed from a liquid transfer line 1, for example a crude oil pipeline, through a sampling probe 2 and returned to the transfer line 1 via a return loop 3 and pump 5. At the outlet 4 of the return loop to the transfer line the returning liquid enters the liquid in the transfer line as a jet or jets which agitates the liquid to a substantially homogeneous mixture. The outlet 4 is upstream of probe 2 so that in operation the liquid entering the return loop 3 is uniformly mixed and a representative sample may be withdrawn from the return loop 3 into sample outlet through valves 9 and 10. To ensure mixing of sedimentary layers in the transfer line 1 the jet from outlet 4 is directed upwardly into the transfer line.
