ABSTRACT:
A vapor tight sampler which is used to visually examine flowing liquid or liquids to determine color, gravity and solids content thereof. The sampler comprises a metal block on which are disposed a plurality of clear cylinders which are covered and gasketed at the top and gasketed to the metal block at the bottom. A pressure release plug is provided in each cover. A header is provided in the block for supplying liquid feed. A separate feed line runs from the header to the bottom of each cylinder. Disposed within each cylinder is an aspirating overflow tube to remove liquid and vapors and prevent overfilling of the cylinders. A vent line is provided in the top of each cylinder. The vent lines and overflow tubes are connected to a drain tank through the metal block. The drain tank provides egress to a separator or drain system and a vent line to the atmosphere. Openings are provided in the block below each cylinder for draining purposes. Three way valves are provided in each feed line and also connect with each drain from the cylinders so that it is possible to fill each cylinder, drain each cylinder or both drain and fill each cylinder at the same time with a single valve. During operation of the sampler, a hydrometer is placed in each cylinder with each hydrometer being designed to reflect the gravity of only one of the liquids which are being sampled.
