The invention relates to an evaluation tool and method for inspecting the integrity of any physical industry connections (hereinafter fittings). The tool comprises a first component (21) provided with a recess (23) to facilitate its engagement with a fitting to be evaluated (see FIG. 10); and a second component (20) connected to, and moveable relative to, the first component (21). Movement of the second component (20) relative to the first component (21) establishes a measurement between two surfaces (32, 33 in FIG. 10) of a fitting (34) to be evaluated, e.g. between an adjustable ferrule or nut (32) and a fixed part (33) of a fitting (34). The measurement is directly (27, 28), or indirectly, indicative of one or more predetermined connection conditions (e.g. over or under tightening of the adjustable component). The predetermined connection conditions may be read directly from the tool, remotely via an electronic device, or by late cross-referencing against entries in a database.

A test gas applicator (10) for administering test gas to a test object to be tested for the presence of a leak, comprising a housing (12) surrounding a test gas volume (14) and having a test gas outlet (24) with a membrane material (28) through which the test gas diffuses and/or permeates.

The invention relates to a method for leakage detection on an object flown through by a medium, in particular a pipe or a pipeline. According to the invention, a pattern is identified in the determined values for the change of the flow rate and the pressure of the medium and for a temperature change, and a probability for the presence of a leak is determined based on the identified pattern and due to self-learning systems.

A system for measuring water flows in a sub-network of a water distribution network is provided. The system includes a plurality of sensors, for example pressure sensors, on the network. The system further comprises communication links between the sensor and one a computing device, and a measurement acquisition system. The computing device is configured to retrieve values of measurements, directly or through the measurement acquisition system; use values of measurements to determine values of control variables of a model of the water distribution network which minimize residue values between measurements values and predicted physical values on the network; then use the model parameter with the values of control variables to calculate water flows at the boundaries of the sub-network.

Methods, systems, and apparatuses are provided for detecting and determining conditions of and conditions within a fluid conduit.

A monitor device that is configured for use on flow controls and like industrial devices. The embodiments may include a resonator that is sensitive to vibrations on the flow control. The resonator may generate a non-electrical signal, like pressure waves. This non-electrical signal can transit a conduit to a sensor that can convert the pressure waves into an electrical signal. On valve assemblies, a controller can process the electrical signal to detect potential health or maintenance issues. The controller may, in turn, generate an alert to prompt operators to perform maintenance on the flow control.

A seat leak measurement system for a ball valve is described. The system includes: a ball valve with a cavity drain line, the ball valve including a cavity pressure sensor; a valve seat leak measurement apparatus including: a cable with a connector, the connector having an external grounding cable; an apparatus electronic control system in communication with the valve sensor retrieval fitting and with valves of the valve seat; an fluid inlet line with a quick pipe coupler, the fluid inlet line having an apparatus drain valve and an isolation valve; a pressure indicator transmitter connected to the fluid inlet line, the pressure indicator transmitter in electronic communication with the apparatus electronic control system; a temperature indicator transmitter connected to the fluid inlet line, the temperature indicator transmitter in electronic communication with the apparatus electronic control system; and a flow elements manifold receiving fluid from the fluid inlet line.

A sensor assembly includes a controller, a sensor, and a housing. The housing encloses the controller and sensor and includes a body supporting the controller and a head supporting the sensor. The body prevents exposure of the controller to an external environment, and the head includes slots enabling exposure of the sensor to the external environment.

A processor of a sensor device performs measurement processing by one or a plurality of sensors and transmission processing of sensor data generated by the measurement processing. The sensor device includes a processing routine table that stores a processing routine configured to include, corresponding to an identifier for identifying processing performed by a processor, a type of the processing, an execution trigger of the processing, and trigger information that prescribes a trigger for transmitting the sensor data. The processor controls processing in a processing routine of the processing routine table, based on trigger information, so that the sensor data subjected to measurement processing is immediately transmitted, or temporarily stored in a buffer and transmitted after a predetermined time.
