Aspects of a monitoring system for winemaking are provided.

The invention relates to a method for closed sampling from filling plants comprising the following steps in: filling a sample quantity into a container (1) with a wall (3); applying a reinforcing element (20) to the container (1) with the wall; introducing a fracture point (22) into the wall of the container (1) in the area of the reinforcing element (20); introducing a sampling attachment (30) with hollow tube (40) into the wall of the container (1) in the area of the fracture point (22); filling a sample container (50) connected to the hollow tube (40) once or several times; removing the sample container (50) from the hollow tube (40) and closing the sample container (50); removing the sampling attachment (30) with hollow tube (40) from the container; and sealing the fracture point (22) of the container in the area of the reinforcing element (20).

The subject matter of the invention is also a sampling device, in particular for carrying out the method.

A sampling device includes a pig-retaining pipe, a plurality of pipes extensions, a plurality of pipe couplings, a winch and support jig, a sample spout, a bottom cap, a pig, and a cable. A storage tank holds product-fuel, water, sludge, and a hard volume. The sampling device is used to collect and sample contents of the storage tank. The sampling device is assembled with the pig attached to a bottom cap coupled to the pig-retaining pipe. The sampling device is inserted into the storage tank to the desired depth. Contents of the storage tank enter into the sampling device through openings in the pig-retaining pipe. The winch is used to pull the cable upwards and draw the pig up through the sampling device. As the pig is pulled upwards, contents exit through the sample spout. The contents are stored in a container that is sent to a laboratory for analysis.

A pH sensor with automatic water storage and replenishment, including a substrate, a working electrode, a reference electrode, a first piezoelectric micropump, a water storage device, and a second piezoelectric micropump. The working electrode, the reference electrode, the first piezoelectric micropump, the water storage device, and the second piezoelectric micropump are arranged on the substrate. The working electrode and the reference electrode are each connected to a bonding pad through an electrode lead. The second piezoelectric micropump, the water storage device, and the first piezoelectric micropump are sequentially communicated, and a liquid flows to the working electrode via an outlet of the first piezoelectric micropump.

A container system includes a flexible bag, a probe port, and a probe. The probe port includes an elongated tubular member having an interior surface bounding a first passageway extending between a first end and an opposing second end, the tubular member being made of a polymeric or elastomeric material and being flexible. The probe port also includes a flange coupled to the tubular member and radially outwardly projecting therefrom, the flange being secured to the flexible bag so that the first end of the tubular member projects into a chamber of the flexible bag while the second end of the first passageway of the tubular member is accessible from outside of the flexible bag. The probe can be received within the first passageway of the probe port.

An apparatus includes a body and a fluid sampling conduit disposed within the body. The body is configured to be disposed within a pipe flowing a fluid. The fluid sampling conduit is configured to obtain a sample of the fluid flowing in the pipe. The apparatus includes an odometer wheel coupled to the body and an elastomeric ring surrounding at least a portion of the body. The elastomeric ring is configured to remove material disposed on an inner wall of the pipe as the apparatus travels through the pipe. The apparatus includes a solid sampling subsystem coupled to an external to the body. The solid sampling subsystem includes a capsule, an inlet valve, and a tubing. The inlet valve, when opened, allows at least a portion of the material removed from an inner wall of the pipe to flow through the tubing and into the capsule.

A system and method for accessing contents of a tank through a tank opening disposed on the tank. The system and method may obtain samples, use a sensor to analyze sludge or may clean the tank. The system has a rotatable head connected to a rigid tube having a central axis. The rotatable head is adapted to be inserted through the tank opening. The rotatable head comprises a displacer and a head opening. A flexible tube has an insertable end and an external end. The flexible tube is slideably movable within the rigid tube and has a range of motion relative to the rigid tube so that the insertable end of the flexible tube can be directed by the displacer through the head opening at an angle offset from the central axis of the rigid tube.
