A flow-volume detecting apparatus including a flow-volume detecting unit which measures a flow volume of a measured fluid, a flow-volume state determining unit which determines a flow-volume state of the measured fluid based on an output from the flow-volume detecting unit. The flow-volume detecting apparatus further including a plurality of filters which process a flow-volume signal, and a filter selecting unit which selects a filter that processes the flow-volume signal, wherein the filter selecting unit selects the filter that processes the flow-volume signal according to the flow-volume state determined by the flow-volume state determining unit.

The present invention relates to a device (1) for measuring the oxidation stability and/or the thermal stability of any type of fuel, including diesel fuel, by miniaturization of the test system by use of a microfluidic technique. The physical phenomena to which fuels are subjected are reproduced by the microchannels (12) of the microfluidic chip (7), which comprise a representation of at least one of the fuel injection and the fuel circulation for a drive system, an internal-combustion engine or an aircraft reactor for example.

Gas meters are provided including a housing and a pressure regulator integrated with the housing. The pressure regulator is configured to adjust pressure of gas flowing through the gas meter responsive to a signal from a remote location or automatically based on a predetermined pressure threshold programmed into the gas meter.

Apparatus and associated methods relate to simultaneously pumping and measuring density of an aircraft fuel. The aircraft fuel is pumped by a centrifugal pump having an impeller. A rotational frequency of the impeller is determined while the centrifugal pump is pumping the aircraft fuel. Flow rate of the aircraft fuel through the centrifugal pump is sensed. Pressure of the aircraft fuel is measured at two different points within or across the centrifugal pump or a differential pressure is measured between the two different points while the centrifugal pump is pumping the aircraft fuel. Density of the aircraft fuel is determined based on a head-curve relation characterizing the centrifugal pump. The head-curve relation relates the fuel density to the rotational frequency, the flow rate, and pressures at the two different points or the differential pressure between the two different points.

A system and method includes a seed roll of a saw type gin stand which can easily be inspected in an efficient and safe manner within the normal course of operation. The monitoring of the seed roll is desirable for prediction of irregularities that could significantly hamper the production of a ginning facility. This monitoring can take place by manual inspection with the eye or touch of the operator. In addition, this feature will facilitate the opportunity to introduce a new automatic process by which the control system can monitor the seed roll in order to improve overall productivity of the gin stand.

Devices, systems and methods for leak detection are provided herein. Also provided are devices, systems and methods for monitoring and/or measuring fluid usage. In some aspects, a system comprising a sensor, a processing system, and a platform are provided. In some aspects, the sensor may be coupled to a spinning device. The sensor can be configured to detect fluid data, which can comprise, for example, displacement data of liquid and/or movement data associated with the liquid in a container and/or flow data associated with a flow of fluid in a conduit. The processing system can be coupled with the sensor and configured to communicate the fluid data. The platform can comprise an application communicatively coupled to one or more databases storing evaluation data (e.g., known pattern data) and configured to receive the fluid data and determine if there is a leak.

An electronic sensing and allocation system is provided for a distributed water infrastructure containing a plurality of differing appliances. The system may receive, from at least one sensor upstream of the plurality of differing appliances, a plurality of signals indicative of water usage within the distributed water infrastructure. The system may output a first indication of a first volume of water together with an indicator attributing the first volume of water to a first rate schedule, and output a second indication of a second volume of water together with an indicator attributing the second volume of water to a second rate schedule. The system may enable billing of the first and second volumes of water to a consumer at differing rates based on differing uses.

A drilling fluid flowback tracking system and method for determining quantities and qualities of drilling fluid returned from the wellhead in drilling operations, providing a frame, a receiving pipe, a riser pipe, and a surge suppressor for conveying returned drilling fluid, a tapered fluid bin having a calibrated drain slot, which retains fluid at a level corresponding to the inflow rate of the fluid, and flow rate marks for visual correlation of the highest level of outflow with the flow rate of the inflow. Collection and retention of data is further provided through sensors in an inline sensor housing communicating through a data cable with a data collection unit. Remote access to the data collection unit is further provided through a data transceiver and remote data unit.
