A servo-electric actuated sampler can draw samples of fuel liquid from an operating main line. The sampler can run in a fast-loop process whereby liquid is drawn into the sampling system and past an actuated sampler and then out of the system back into main. The system main run a short loop whereby the main fast-flow is restricted, and the actuator and sampler are isolated from the main line flow. When isolated, the sampler discharges liquid into sampling cans. The servo-electric actuator requires a monitored amount of power to draw and discharge fluids. Monitoring of the power requirements of the servo-electric sampler can reveal the status and reliability of the system.

A testing device for testing the level of a selected chemical in central heating system water in a central heating system circuit comprises: a sample chamber for holding a sample of central heating system water, the sample chamber being connected to the central heating system circuit; means for controlling filling of the sample chamber with central heating system water from the central heating system circuit, and emptying of the sample chamber; at least one valve for isolating the sample of central heating system water from the heating circuit during testing; and optical testing apparatus including a light source and a detector, for measuring an optical property of the sample of central heating system water isolated within the sample chamber and thereby making a determination as to whether or not the level of the selected chemical in the water is greater than a predetermined threshold level.

Methods and systems for collecting high quality reservoir samples and delivering EOR substances are disclosed. The systems and methods disclosed are especially important for collecting samples of reservoir samples in a manner that most closely resembles production fluids and maintains the samples at or above the bubble point of the fluid.

Apparatus and a method are provided for bringing a well-fluid sample in a well through a sampling device which is in fluid communication with the apparatus. The apparatus includes: a dump chamber for receiving the well-fluid sample; a first hydraulic piston arranged in a first cylinder housing; a second hydraulic piston arranged in a second cylinder housing; a piston rod for mechanically connecting the first piston to the second piston to form a piston arrangement, the dump chamber being defined by the first piston and a portion of the first cylinder housing. The apparatus further includes at least one holding device arranged to switch between an active position, in which the piston arrangement is held fixed against movement, and an inactive position, in which the piston arrangement is allowed a movement relative to the cylinder housings.
