Abstract |
A runoff sampling device is described that will automatically start itself, collect samples, and cease operation after a predetermined time period. The sampler must be reset for the next runoff event. The sampler may also be utilized to collect samples resulting from irrigation runoff. The major design parameters imposed upon this device were: (1) Activation whenever runoff occurred; (2) Samples taken at preselected time intervals; (3) Continuously record quantity of runoff; (4) Prevent intermixing of successive samples; and (5) Deactivate all circuitry after completion of sampling cycle. Illustrations show the unit with sample containers mounted on a turntable and the schematic wiring diagram for the sampler. A small capacity pump and flexible tubing delivers water to the sampler containers. The unit may be designed to operate on alternating or direct current. (Author) |
