A device for monitoring manual flushing of a hydrant includes an adapter attached to a flushing hose and attachable to an outlet of a water hydrant, an access port on the adapter, the access port being sized to take a sample of a stream of water flowing through the adapter, a flexible hose attached to the access port, an analyzer box containing a sensor adapted to sense a characteristic of water, the sensor being operatively connected to the flexible hose, and an alarm operatively attached to the sensor.

A sampler for taking samples from a molten metal bath includes a carrier tube having an immersion end; sample chamber assembly comprising a cover plate and a housing, wherein the housing comprises an immersion end having an opening; an inflow conduit having a first end for receiving molten metal and a second end, opposite the first end, wherein the second end is in communication with the opening, and the opening is configured to receive the molten metal from the inflow conduit; a measuring head, wherein the sample chamber and the second end of the inflow conduit are at least partly arranged in the measuring head; and a metal bushing, wherein the metal bushing coupling the inflow conduit to the sample chamber.

A drifting buoy sampler system for a stormwater discharge plume formed from stormwater discharged into coastal waters. The system compresan electronics sampling pod for collecting integrated water samples within the stormwater plume as the buoy system drifts with the stormwater plume near the water surface as the plume travels out to sea. The pod includes a watertight section including a GPS/radio module for providing GPS (geo-position) location information and a processor for monitoring and controlling the sampling rate, a pump module and a battery module; a passive sampler bag for collecting the integrated water samples; a free flooding section including a composite sample bag module such that the pump module pumps collected samples from the passive sampler bag to the composite sample bag module at a predetermined sampling rate and a ballast module for providing ballast to the system when drifting within the plume.

The present invention refers to a method for the isokinetic sampling of liquids and gases present in streams having many fluid phases, and to an apparatus suitable for achieving it. The method and apparatus have application in particular in the field of oil extraction, wherein, after the extraction of liquid and gaseous hydrocarbons possibly accompanied by water and suspended solids, it is necessary to know the composition of the mixture extracted and also the flow rate of the single phases.

The present invention relates to a test film for detecting surface particles in a clean room in order to prevent inferior products by measuring the contamination level of the clean room using the surface particles. The present invention provides a test film for detecting surface particles in a cleanroom, the test film comprising a substrate which has a predetermined thickness and is formed of a transparent synthetic resin material; a first adhesive layer which is formed at one side of the substrate and collects the surface particles; a release film which is adhered to the first adhesive layer and is separated from the first adhesive layer when the surface particles are collected; a second adhesive layer which is formed at the other side of the substrate; and a protective film which is adhered to the second adhesive layer so as to protect the substrate and has gradations indicated thereon. According to the present invention, there is an effect in that it is possible to easily and quickly check whether or not a clean room is contaminated by collecting, on the adhesive layer-applied surface of a substrate to which an adhesive is applied, surface particles adhered to an object to be measured, and then measuring the number, size, distribution, etc. of the surface particles with the naked eye or using instruments such as a light, a magnifier, a microscope, or the like.
