ABSTRACT:
Apparatus for removing liquid samples, especially milk samples, from a flow facility wherein a feed pump, an electromagnetically actuated and normally closed metering valve physically located at a higher level than said feed pump, an air eliminator and a volume meter are sequentially arrayed downstream. The metering valve (7) is connected to flow line (6) by a short connecting pipe (15) sealed by closing element (11), the drain tube (8) of this valve leads to a sample container located above closing element (11) and defined by channel (14) traversed by valve shaft (13), which leaves annular gap (29) between the outer surface of the valve shaft (13) and the wall of channel (14) and which is large enough as to just suffice in cross-section to pass the amount of liquid sample to be removed.
