Abstract
Liquid sampling devices and methods for sampling flowing or other liquid to determine its composition. The preferred sampling device has an upper liquid catch basin 40 for receiving a liquid to be sampled, a lower sample collection chamber 20, a liquid inlet 24 communicating the basin and collection chamber, and an inlet valve 26, 28 for closing the inlet against entry of liquid and foreign matter into the chamber and escape of liquid and vapor from the chamber except when the inlet is submerged in liquid to be sampled and the collection chamber contains less than a predetermined volume of the liquid. The sampling device is placed in sampling position such that the inlet valve 26, 28 remains closed until liquid covers the inlet 24, whereupon the inlet valve opens to permit liquid flow into the collection chamber 20 and later recloses in response to filling of the chamber with a predetermined sample volume. Exemplary uses of the sampling device are sampling storm water runoff from industrial property to determine the contaminants, if any, absorbed by the storm water as it flows across the property, and sampling liquid leakage in a brewery or other liquid processing facility to aid in locating the leak.
