    • A sampler for collecting vertically continuous media samples from aggregate liquid filtering systems. The sampler includes a sample collecting lower section have an inner member rotatably carried within an outer member. These lower members have slots which may be aligned by relative rotation of the members. An upper extension section has inner and outer members which are releasably coupled to the lower inner and outer members. The extension section has handles which allow manual rotation of the inner members relative to the outer members. The handles are used to insert the sampler into an aggregate bed, open the slots to collect a sample, close the slots and remove the sampler from the bed.

    • 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.

    • 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.

    • 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.

    • 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.
    • 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。

    • A storm water runoff first flush sampler is provided which includes at le one container which has a top and a bottom. A water collection device is also provided which has an inlet end for collecting water and an outlet end for discharging the collected water. The inlet end of the water collection device is located above the top of the container, and the outlet end of the water collection device opens into the container for filling the container with water. A device is also provided for venting air from the container as it is filled with water and discharging the vented air at a level above the top of the water collection device. This arrangement enables automatic termination of gravity flow to the container when water reaches the level of the water collection device. Also, the water collection device is provided with an aperture that releases the kinetic pressure resulting from water falling onto the inlet end of the water collection device, thereby preventing alteration of the composition of the original sample by additionally collected water. Further, the liquid collection device has a P trap which will prevent sediment from additional runoff water from entering the container after the container is full.
    • 提供暴雨水径流第一冲洗取样器,其包括至少一个具有顶部和底部的容器。 还提供一种具有用于收集水的入口端和用于排出收集的水的出口端的集水装置。 水收集装置的入口端位于容器的顶部上方,并且收集装置的出口端开放到用于用水填充容器的容器中。 还提供一种装置,用于在容器充满水并且将通风空气排放到集水装置的顶部上方的水平时从容器排出空气。 当水达到水收集装置的水位时,这种布置使得自动终止重量流向容器。 此外,水收集装置设置有孔,其释放由于水落入收集装置的入口端而产生的动力压力,从而防止通过另外收集的水来改变原始样品的组成。 此外,液体收集装置具有P捕集器,其将在容器充满之后防止附加径流水中的沉淀物进入容器。
