Title: Liquid sample taken with non-representative liquid eliminated - by temporary storage then return to process system(BE-27.2.76)
Inventor: FRITZSCHE ALBERT DR ING
IPC: G01N1/14
Filed: 1974-08-31
Abstract: A device for obtaining a liquid sample from a vessel or pipeline, while at the same time excluding the volume of liquid contained in the tapping line leading form the process liquid (vessel or pipeline) to the sampling line is constructed as follows: the tapping line has a piston pump with separately operated suction and expulsion strokes connected to the end of this tapping line which is nearest to the sampling line; the capacity of this pump is at least sufficient to draw of the entire liquid contained in the tapping line; branched off from the end of the tapping line is the sampling line containing a multi-way valve, providing a connection to a second piston pump; when a sample is to be measured from the process liquid, the first pump is first used to draw off the entire liquid in the tapping line, since this liquid may be unrepresentative; while this is stored in the pump, the sample which follows it down the tapping line arrives at the T-region adjacent to the multi-way valve; this valve is then set so that when the piston is drawn back, the sample is drawn into this pump; by again closing the valve from the upward direction and opening it down to the sampling line, and then advancing the piston, this sample is expelled into the sampling line. By resetting the valve and advancing the first piston, the non-representative liquid can be returned to the process line.
