The present invention relates to a mobile system for continuous, automatic, online monitoring of water quality and particle sampling in a drinking water distribution network, comprising: a mobile unit provided with means for supplying, from at least a selected one of the plurality of points in the drinking water distribution network, a corresponding, selected influent fluid sample stream; means for discharging a corresponding, selected effluent fluid sample stream; for each selected influent fluid sample stream, a respectively associated continuous monitor module.

An arrangement forming a lubricant circuit includes at least one lubricant line, at least one line branching that branches the lubricant line into a first branch and a second branch. The arrangement further includes at least one lubricant reservoir integrated into the first branch, and at least one line junction where the first branch and the second branch merge. The first branch is lockable and releasable.

An apparatus and a method to withdraw samples from a polymerization plant using a defined sequence of steps combined with locking devices for valves opened by a single key.

A system and method for accurate, automated collection of a sample of a process fluid flowing through a transport line includes: a first container for collecting the sample and being pre-filled with a displacement fluid immiscible with the process fluid; a second container having smaller volume than the volume of the first container, for collecting the displacement fluid; an actuated valve positioned between the first container and the second container and actuated by a controller to move from an open position to initiate collection of the sample in the first container and transfer the process fluid displaced from the first container into the second container, and to move the actuated valve to the closed position upon receiving a signal from the fluid level sensor regarding level of fluid in the second container.

Example aspects of a pit assembly, a fluid testing system, and a method for using a fluid testing system are disclosed. The pit assembly can comprise a pit housing; a curb stop assembly comprising a curb stop valve, the curb stop valve mounted within the pit housing; and a pressure transducer mounted within the pit housing.

A chiller water sampling device includes a pair of flow meters and a proportional valve to provide a constant flow rate of sample water containing peroxyacetic acid from a chiller to a mixing tank. Acid can be added to reduce the pH of sample water in the mixing tank to bring the pH within the operating range of a peroxyacetic acid sensor. The sensed level of peroxyacetic acid can be used to control further addition of peroxyacetic acid to the chiller.

The present disclosure provides for analysis systems that are configured to extract a fluid sample from a fluid (e.g., aqueous solution) in a reactor (e.g., bioreactor) at a first rate and then flow the fluid sample to a sensor system at a second rate to analyze the fluid sample. The sensor system can detect the presence and/or concentration of molecules (e.g., biomolecules such as biomarkers (e.g., metabolites, proteins, peptides, cytokines, growth factors, DNA, RNA, lipids) and cells of different types and cell properties, e.g., mechanical stiffness, etc.)). The data obtained can be used by a feedback control system to modify, as needed, the conditions in the reactor to enhance the productively of the reactor.

A fluid sampling unit includes a housing and a shutoff valve adapted to selectively permit and restrict fluid flow to a fluid line disposed within an internal cavity of the housing. An electrically-actuated valve is disposed within the housing downstream from, and in fluid communication with, the shutoff valve. A first metallic line including copper is disposed within the housing in fluid communication with and between the shutoff valve and the electrically-actuated valve. A second metallic line including lead is disposed within the housing in fluid communication with and between the shutoff valve and the electrically-actuated valve. A control unit includes a controller adapted to selectively actuate the electrically-actuated valve.

The present invention relates to a method and system for measuring total chloride content in a process product stream. In particular, the present invention relates to a method of measuring hydrogen chloride and organochloride content, in situ, for a gaseous refinery process product stream. This method allows for measurement of hydrogenchloride and organochloride content in a single test method, which allows for optimised performance and maintenance schedules for chloride guard beds used within the refinery process.

A sampling device for taking samples from a gaseous beverage under pressure includes a connection for a beverage line, a pump having a pump chamber, a particle filter, a discharging opening for a beverage sample, an outlet for waste, a control device, and a line system connected to the pump chamber with adjustable valves. The sampling device is configured so a beverage sample with a volume smaller than the volume of the pump chamber is introduced from the connection into the pump chamber. The pump chamber is then separated from the connection and is expanded so gas exits from the beverage sample. The pump chamber is then connected to the outlet opening and compressed so gas which has passed out of the beverage sample is displaced. Then, the pump chamber is connected to the discharging opening via the particle filter and compressed so the beverage sample is displaced.
