摘要： An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the "as collected" condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (e.g., mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The preparation sub-system may comprise a slurry recirculation flow loop configured with devices to stir, measure, and adjust a water to solids ratio of the slurry.

摘要： A plumbing system including a pump noise dampener is provided. The plumbing system comprises: a pump to output a flow of process liquid; a measurement device to measure a flow rate of the process liquid output from the pump; and a process line coupling the output of the pump to an input of the measurement device. The pump noise dampener is disposed between the pump and the measurement device. The pump noise dampener comprises a bladderless, single chamber pressure vessel to hold the process liquid at a prescribed pressure and an isolation valve tying the pressure vessel into the process line in order to control a flow of the process liquid output from the pump into and out of the pressure vessel and to the measurement device. The pressure vessel is further configured to dampen noise of the process liquid output from the pump and input to the measurement device.

摘要： A pulsation dampener system (300) is provided. The pulsation dampener system includes a pump (310) that pumps fluid through the pulsation dampener system. A pulsation dampener (312) is located downstream from the pump and dampens pulsations within the fluid. A pressure sensor (315) is located downstream from the pump and detects a pump pressure of the fluid at the pulsation dampener. A wye pipe (303) located downstream of the pulsation dampener and the pressure sensor that diverts the fluid into two or more flow paths. From the wye, a first flow path (302C) increases pump pressure of the fluid and a second flow path (302D) allows the fluid to flow unrestricted. Piping (302E) receives the fluid from the first flow path and the second flow path and discharges the fluid further downstream.
