A liquid container refill management system including a machine learning algorithm and method of training the same, the system and method making use of noninvasive tank-in-tank measuring techniques. The system can comprise of a container fill level indicator. The container fill level indicator can be capable of detecting a vibration response signal on the outer surface of a container, wherein the system is capable of transmitting the response signal to a remote data processor for processing using a trained machine learning algorithm. The trained machine learning algorithm can be trained by the process of selecting model inputs and outputs to define an internal structure of the machine learning algorithm, applying a collection of input and output data samples to train the machine learning algorithm, and verifying the accuracy of the machine learning algorithm by applying input data samples and comparing received output values with expected output values.

A method for testing a container (11) having an interior volume (12) for tightness, comprising the following steps: providing the container (11) in a pressure chamber (10) and reducing pressure within the pressure chamber (10) or increasing pressure within the container (11) as far as a predefined test pressure, ascertaining a pressure profile (100) within the pressure chamber (10) over time, comparing the pressure profile (100) to a reference profile (200) in order to determine whether a leak is present within the container (11), wherein ambient conditions of the container (11) and/or the pressure chamber (10) are monitored and the reference profile (200) is adapted to changing ambient conditions.

Subsea equipment-protection apparatus including a fluid monitoring apparatus for detecting a first fluid, a second fluid and a third fluid. The fluid monitoring apparatus including a first float having a density less than that of the first fluid but greater than that of the second fluid; a second float having a density less than that of the second fluid but greater than that of the third fluid; and a sensor configured to detect the first and second floats so that the position of the floats can be determined. The first float floating when a fluid with density greater than the first float is present and sinking when a fluid with density less than the first float is present. The second float floating when a fluid with a density greater than the second float is present and sinking when a fluid with a density less than the second float is present.

The present invention defines six unexpected benefits resulting from the automation of and improvements to inventory reconciliation and tank level monitoring at tank farms, terminals and refineries, commonly associated with refining and the transportation of, hydrocarbon fuels. In the implementation of an automated system for tank level monitoring and periodic inventory reconciliation, it has been discovered that both applications can be used to correctly identify maintenance needs and policy violations that were previously unable to be identified. The benefits include identification of thermal relief valve failure, transmix check valve failure, lock out/tag out failure, floating roof landing, and incorrect tank assignments.

A transformer system includes a transformer and a transformer tank housing the transformer in a bath of a coolant; and a plurality of radiator systems operative to transfer heat from the coolant, each radiator system being in fluid communication with the transformer tank. The transformer system also includes means for determining an occurrence of a potential coolant leak in one or more radiator system of the plurality of radiator systems; and means for isolating only radiator systems of the plurality of radiator systems that are leaking, in response to a determination of the occurrence of the potential coolant leak.

Exemplary embodiments disclosed herein are directed to systems and methods by which the level of liquid nitrogen in one or more liquid nitrogen storage containers can be monitored and leaks may be detected and reported.

A flushing system has a water reservoir; discharge equipment enabling delivery of water into the toilet bowl; the triggering member, which enables the water to be delivered via the discharge equipment; the normal operating mode in which the water is transferred by the triggering member; the standby mode in which the predetermined quantity of the water is transferred at the first predetermined period; the level measurement member enabling the level of water within the reservoir to be determined at a second period; the control panel comprising the first control member enabling the flushing system to operate in normal or standby mode; and the control unit for containing the information about the optimum water level within the reservoir, for comparing the level data to the optimum level information, for enabling the predetermined quantity of the water to be delivered at the first period when the flushing system is in standby mode.

The present invention is directed to a process, which can be used in the production of exhaust catalysts. In particular, the present process describes way of testing the leak-tightness of the coating equipment before a new coating campaign begins or during a running campaign.

An agricultural sprayer includes a purge tank and first and second nozzles. Furthermore, the system includes a first valve fluidly configured to selectively permit air to flow to the first nozzle and a second valve fluidly configured to selectively permit the air to flow to the second nozzle. A computing system is configured to receive an input indicative of initiation of a purging operation and, upon receipt of the input, control an operation of a main valve to allow the air to flow through a main fluid conduit. Furthermore, the computing system is configured to monitor the air pressure associated with the purge tank and control the operation of the first and second valves during the purging operation based on the monitored air pressure.
