摘要： The sampler comprises a vessel assembly for taking, conducting, and storing a fluid sample to be stored at a predeterminable storage temperature as well as a cooling assembly, thermally coupled to the vessel assembly, for cooling the fluid sample. The cooling assembly has a first cooling volume, which encompasses the vessel assembly, and a second cooling volume, which jackets the vessel assembly. To cool the fluid sample, the internal temperature of the vessel assembly is lowered by means of the cooling assembly prior to and/or during the dispensing of the fluid sample, and the fluid is subsequently conducted or held in the vessel assembly.

摘要： A composite wastewater sampler includes a flow-through-chamber having an inlet port and an outlet port with a path between them that gradually increases in depth and width and then decreases in width. It is shaped to cause fluid to: (1) flow from the inlet port; (2) drop to a lower level of flow within the flow-through-chamber; (3) gradually adjust in cross-sectional shape to the outlet port; and (4) flow back into a wastewater pipe. A sampling nozzle extends into the flow-through-chamber adjacent to the inlet port and within the path of the downwardly flowing wastewater so that wastewater exiting the port contacts the nozzle and flows downwardly across it.

摘要： A robotic sampling device has a maneuverable, telescoping sample collector comprising a sample collecting arm and a propulsion module containing means for supporting and facilitating movement. Most preferably, the means for supporting and facilitating movement are wheels. The robotic sampling device also contains means for increasing traction for the propulsion module. The sampling device is remotely controlled. The sampling device contains at least one light source and a viewer that provides information for navigation and sample collection. The wheels of the propulsion module contain extendable pins which promote increased traction. The telescoping sample collector may also be rotated or tilted through a 180 degree arc relative to the axis of the pipe. The robotic sampling device also provides a means for collecting, labelling, and storing a sample, as well as cleaning the sample collector in preparation of another sampling event.

摘要： To draw samples of fluid at remote locations, one of a plurality of sampler configurations is selected from configuations that have a universal base, a selected one of a composite container holder or locator, 12-container rain water runoff container holder and sequential sample multiple container holder; clampdown, control section and cover. The selected configuration is brought to the remote site. Samples are drawn at the site in a predetermined time sequence. After a sequence is completed, a new selected container carrier is put into an insulated shipping carton with ice and containers and brought to the site. At the site, the old container holder is removed and the ice is poured into the shipping carton. The new container carrier is inserted into the sampler and ice put in with it. The old container carrier with sample in the containers is put into the shipping carton with the remaining ice and brought to the laboratory.

摘要： This invention provides a method and apparatus for transmitting and sensing liquid pressure (head) and liquid level (depth) in flow metering, tide gauge and liquid salinity or slurry density measurement applications. The invention essentially eliminates the effect of pressure sensor temperature variations and the effect of long-term pressure sensor signal drift on pressure sensing accuracy by resetting the zero and gain of the pressure sensor prior to pressure measurement. A variety of sources of a known differential pressure may be used to reset the gain of the differential pressure sensor by simultaneously exposing both sides of the differential pressure sensor to the known differential pressure. In one embodiment of the invention, the head loss through exhaust port of a spring-biased comparitor is the known pressure differential used to reset the pressure sensor gain. In another embodiment, a U-tube manometer is used to set a known differential pressure across an adjustable differential pressure regulator or an adjustable spring-biased comparitor and that pressure differential is used. The invention provides accurate bubbler pressure measurement under conditions of rapidly varying liquid head by means of a single calibration of a differential pressure sensor instead of sequential calibrations of a gauge pressure sensor. The present invention provides a compact and lightweight manifold-mounted pneumatic integrated circuit and a method for in situ recalibration of relatively inexpensive pressure sensors.
摘要翻译：本发明提供了一种用于在流量计，潮汐计和液体盐度或浆料浓度测量应用中传输和感测液体压力（头部）和液位（深度）的方法和装置。通过在压力测量之前复位压力传感器的零点和增益，本发明基本上消除了压力传感器温度变化的影响以及长期压力传感器信号漂移对压力感测精度的影响。可以使用已知压差的各种来源，通过同时将差压传感器的两侧暴露于已知的压差来重置差压传感器的增益。在本发明的一个实施例中，通过弹簧偏置的比较器的排气口的头部损失是用于复位压力传感器增益的已知压力差。在另一个实施例中，使用U型管压力计来设置跨越可调压差调节器或可调节弹簧偏置的比较器的已知压差，并且使用压力差。本发明通过差压传感器的单次校准而不是表压式传感器的顺序校准，在快速变化的液体头的条件下提供精确的起泡器压力测量。本发明提供了一种紧凑且重量轻的歧管安装的气动集成电路和用于相对便宜的压力传感器的原位重新校准的方法。
