The measuring-device system comprises two measuring devices and an evaluating- and supply electronics. Each of the measuring devices has a measured variable transducer and a measurement transmitter. Each of the transducers is adapted to react to a measured variable and to provide a corresponding transducer signal. The first measurement transmitter includes an interface circuit both for wired energy supply and for wired signal transmission on a two-wire loop. The second measurement transmitter includes an interface circuit for wired energy supply and a radio unit. The evaluating- and supply electronics feeds electrical power into the two-wire loop during operation. Both measurement transmitters are adapted to draw electrical power from the electrical current loop. Additionally, the first measurement transmitter is adapted to transmit its measurement signal via the electrical current loop to the evaluating- and supply electronics.

A nozzle gas flow sensor and a method thereof are provided. The nozzle gas flow sensor includes circuitry configured to receive sensing signals (readings) from a sensing element, each indicative of a flow rate of shielding gas ejected from a nozzle of a torch; analyze the flow rate; and evaluate the stability of the flow rate of the shielding gas with a window of operation. The nozzle gas flow sensor may include an indicator indicative of the evaluation result. The torch may be a welding torch, a cutting torch and/or a spraying (coating) torch.

In a temporally continued plurality of day-and-time sections, history data included in the past day-and-time section is graphically displayed on the basis of the integrated flow amount data stored in the storage unit, as an integrated flow amount in each day-and-time section. In the day-and-time section including the current day-and-time, the integrated flow amount in the day-and-time section based on the current integrated flow amount data is successively updated and graphically displayed.

To provide an apparatus for monitoring a fluid flow rate, which is capable of performing monitoring without a data deficit, and displays information on a trend of a past history. A monitoring apparatus accepts, from the flow meter, integrated flow amount data for every day-and-time section, and a current flow rate, and graphically displays, on the basis of the integrated flow amount data for every day-and-time section, an integrated flow amount corresponding to each day-and-time section, on the basis of the integrated flow amount data for every day-and-time section including the current day-and-time and for every another plurality of continuous day-and-time sections.

A work vehicle for tracking a payload through a dump cycle having am implement, a volume sensor, a location tracker, an operation sensor, and a computing device. The volume sensor may be configured to sense a volume of material in the implement and generate a corresponding volume data signal. The location tracker may be configured to generate a location data signal indicative of the location of the implement. The operation sensor may be configured to detect an operation characteristic of a dump cycle of the implement and generate an operation data signal indicative of the operation characteristic. The computing device may be operable to execute a payload tracking algorithm to receive the volume data signal, the location data signal, the operation data signal, store the input signal to generate a tracking metric corresponding to the payload.

Provided is a flow meter capable of logging data more reliably. In this operation, a detection element repeatedly detects a physical quantity related to a flow rate of a fluid flowing in a pipe in a predetermined sampling cycle. Based on physical quantities, a calculation part sequentially calculates the flow rate of the fluid in the pipe. Further, a time measurement part calculates the time. A control storage part is caused to store a logging target, a logging cycle, and logging start definition information. Based on the logging start definition information, a control part automatically starts logging of the logging target in response to startup of the flow meter, and causes a log storage part to store the time measured by the time measurement part and a numerical value of the logging target in association with each other in every logging cycle.

An apparatus for dispensing a towel and/or a liquid, which stores information pertaining to an amount of the towel and/or liquid that is arranged in the apparatus and/or dispensed by the apparatus. The apparatus stores the information in a control data memory that is able to be written to only once. The control data memory is part of a radio chip. The apparatus stores the information pertaining to the dispensed amount in a comparison data memory that is erasable and rewritable. The apparatus automatically compares the information pertaining to the dispensed amount of the towel and/or liquid that is stored in the control data memory and in the comparison data memory with one another. The apparatus prevents the towel and/or liquid from being dispensed, or stores the information pertaining to the amount that is stored in the control data memory in the comparison data memory, if the information of the control data memory and that of the comparison data memory are not consistent with one another.

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.

A system is provided for tracking usage of a plurality of water appliances in a distributed water infrastructure. The system may comprise at least one processor configured to receive, from a location in the distributed water infrastructure upstream of the plurality of water appliances, historical water usage measurements; determine from the historical water usage measurements at least one unique water usage signature associated with each of the plurality of water appliances; receive, from the location in the distributed water infrastructure upstream of the plurality of water appliances, current water usage measurements; determine from the current water usage measurements at least one current water usage signature; compare the current water usage signature with at least one of the unique water usage signatures stored in memory to determine a match; and, based on the signature match, ascertain an identifier of a water appliance in current use.

Disclosed is a method for detecting domestic hot water use by a sanitary fitting during an observation period by analysing data relative to volumes of water passing through a water meter, the method including: receiving a first item of data, noted V1, representing the maximum volume of fluid measured over a predetermined period, preferably equal to 5 minutes; receiving a second item of data, noted V2, representing the maximum volume of fluid measured by the meter during another predetermined period, preferably equal to 15 minutes; and detecting that domestic hot water has been used when V1>15 litres and V220 litres.
