A method operates a counter device for a fluid which can be connected via a connecting device to a meter point having at least one line through which the fluid flows. A control device is configured when connected via at least one operating parameter specific for the meter point and/or a meter point environment. When the counter device is taken into operation, the operating parameters are called up by a communication device on the counter device side communicating wirelessly by radio via a communication link with a passive communication device on the meter point side. The operating parameters are stored in a storage device of the passive communication device.

A drug delivery device system with mutable indicia and method for using same are provided. The drug delivery device system includes a syringe and/or syringe components (e.g., needle shield, needle guard), or autoinjector pen, or wearable autoinjector with mutable indicia and a software application for an external device to analyze images of the mutable indicia to automatically determine and record status of the drug delivery device.

The present invention relates to a system for estimating the individual water consumption of a plurality of devices supplied by the secondary fluid distribution network of a user. The system comprises a sleeve able to be fitted around the supply pipe of the secondary network and comprises an electromechanical sensor placed against the outside wall of the supply pipe, and a processor for analyzing the signals delivered by the electromechanical sensor with a view to extracting information characterizing the individual consumption of the devices supplied by the secondary network.

A method for determining a flow rate of a fluid includes positioning a tubular within a wellbore formed in a subsurface formation, wherein a flow of fluid is to move through the tubular. An orifice plate is positioned in the tubular. The orifice plate is movable between a first position and a second position to alter a flow area of the flow of fluid moving through the tubular. The method includes detecting a change in a downhole attribute that changes in response to the alteration of the flow area of the flow of fluid. Sensors positioned within or in communication with an interior of the tubular can detect the change in the downhole attribute. The method further includes determining a flow rate of the flow of fluid based on the detected change in the downhole attribute. The flow of fluid may be single phase or multiphase.

By implementing a monitoring system to a fluid meter set, the meter set can be monitored for abnormalities including fluid leaks or other system failures as well as gas blend or gas density. A monitoring system that uses sensors such as vibration sensors can detect fluid leaks or other system failures based on abnormal conditions such as vibrations of the meter set. Sensors may be positioned at various locations along the meter set where leakage of fluids or other system failures may be possible. Sensory information detected by sensors are communicated to processing or control unit which can trigger an alarm signaling unit alerting of a potential fluid leak. Such a system of monitoring the integrity of a fluid meter set can help to quickly identify and respond to a fluid leak without necessarily relying on visual or olfactory cues associated with the fluid being leaked.
