A system is provided for tracking, in a distributed water infrastructure, water usage by category. The system may comprise at least one processor configured to receive from at least one sensor associated with the distributed water infrastructure signals indicative of water usage in the distributed water infrastructure. The system may, based on the signals indicative of water usage, construct a plurality of profiles. The system may assign each profile to one of a plurality of water usage categories. The system may collect, from the at least one sensor, signals indicative of water usage for substantially all water delivered through the distributed water infrastructure in a time period. The system may construct a plurality of water usage profiles in the aggregate, encompassing substantially all water delivered through the distributed water infrastructure in the time period. The system may assign each constructed water usage profile to one of the plurality of water usage categories. The system may output, for display, water usage for the time period for each of the plurality of water usage categories.

Embodiments of systems and methods are provided to monitor operation of a compound water meter comprising a low flow meter and a high flow meter. In the disclosed embodiments, a first sensor package is coupled to the low flow meter to generate a first set of sensor data for monitoring operation of the low flow meter, and a second sensor package is coupled to the high flow meter to generate a second set of sensor data for monitoring operation of the high flow meter. The first and second sensor packages may each include, e.g., an optical sensor, a magnetic sensor and a vibration sensor. In the disclosed embodiments, the first and second sets of sensor data are analyzed to detect various potential problems within the compound water meter, such as a register failure, a crossover failure, a measurement failure, a bypass open condition and/or an incorrect flow meter size.

A differential monitoring system of carbon dioxide levels within an associated building with a monitoring zone including a quantity of captured carbon dioxide and a reference zone that is spaced away from the monitoring zone. The differential monitoring system includes a first carbon dioxide monitoring inlet disposed within the monitoring zone. A second carbon dioxide monitoring inlet is disposed within the monitoring zone in spaced relation to the first carbon dioxide monitoring inlet and/or is disposed within the reference zone in spaced relation to the first carbon dioxide monitoring zone. A controller is operable to determine when a carbon dioxide level at the second carbon dioxide monitoring inlet exceeds a carbon dioxide level at the first carbon dioxide monitoring inlet by a predetermined differential threshold. The inlets can be part of an aspirated sampling system and/or part of a distributed sensor system. Methods of monitoring carbon dioxide levels are also included.

A system for measuring the flow rate of a fluid medium includes an input line of a fluid medium, elements for measuring the flow rate of the fluid medium in transit which are interposed between the input line and the output line, and an electronic unit functionally associated with the elements for measuring.

The elements for measuring include at least two connecting lines arranged in parallel between the input line and the output line, and a flowmeter in fluid communication with each one of the connecting lines. A corresponding interval of measurable flow rate values stored in the electronic unit is associated with each flowmeter.

The invention comprises a main and a subsequent stage. At the main stage, the medium is pumped into a first instrument line. This first instrument line is mounted in a main pipeline system and is equipped with an inlet mass meter with a first flow rate range. After reaching of a set value from the instruments, an automated control system (ACS) stops the first line pump, ensures operation of its driving isolation valves, thus, completing the main stage measurement cycle, and switches the system into the subsequent stage mode. At the subsequent stage, the medium flow is collected from the tank and cavities of the measuring system. It flows by gravity into the bottom of the system inner volume (9) and is then supplied by a to a second instrument line equipped by a mass meter with a second and lower flow rate range.
