A fluid distribution manifold may receive a first required flow rate for a first flow of fluid that flows to a fluid handling device or a reservoir. A first operation state may be determined for a first valve assembly that regulates the first flow, the manifold may operate the first valve assembly based on the first operation state, and a first position tracker may be incremented based on the first operation. Based on a value of a cycle tracker, the manifold may identify a second valve assembly in an operation cycle and access a second control input that includes a second required flow rate for a second flow of fluid regulated by the second valve assembly. The manifold may cause the second valve assembly to operate based on at least one of a second operation state and a change in the second actual flow rate resulting from the first operation.

A flow detector for monitoring an adhesive flow in an adhesive applicator includes a sensor device arranged in the adhesive flow. The sensor device is formed as a capacitive sensor.

An all-inclusive fluid flow device that can variably magnify differential pressure, measure, and control a flow of a fluid is described. Various procedures, including measuring, controlling, balancing, or calibration procedures can leverage a variably magnified differential pressure measurement. Differential pressure measurements can be measured across the fluid flow device such that a first pressure measurement is taken upstream of the fluid flow device while a second pressure measurement is taken downstream of the fluid flow device. Moreover, one or more of the various pressure measurements, and in particular the downstream pressure measurement, can be performed at stagnation zone where the flow has stagnated. Such can provide significant magnification and/or turndown capabilities and the magnification can vary based on a damper position and/or apertures dimensions.

A mass flow control apparatus and methods for calibrating and tuning the mass flow apparatus are provided. The mass flow apparatus can be calibrated by receiving a calibration input signal that provides one or more properties of a gas that is flowing through a main fluid flow path and performing one or more measurements, using one or more sensors, on the gas. The calibration includes determining a calibration parameter based on the results of the one or more measurements and the calibration input signal and adjusting a proportional valve, based on the calibration parameter, to adjust a flow rate, of the gas through the apparatus, to match a setpoint flow rate.

A method/structure for calibrating a product fluid flow device having one or more apertures with aggregate area A.sub.o, where fluid flows along a fluid flow path therethrough in response to pressure differentials ΔP across the apertures. Calibration is effected relative to a calibration fluid flow device having a geometry and operational parameters corresponding to those of the product fluid flow device. A piecewise curved calibration controller establishes calibration conditions and generates a discrete point calibration flow rate (dpCFR) Function by measuring at a sparse set of points in a range of interest and determining a piecewise curved mathematical representation of fluid flow through the calibration fluid flow device. Data representative of the CFR function is transferred to a product blade controller, which processes the mathematical representation, and controls fluid flow through product fluid flow device based on values extracted from the received dpCFR Function.

A housing assembly for a manifold includes a first housing with an inlet and a plurality of outlets, a second housing, and a valve retainer engaged with the first and second housings. The valve retainer includes a retention plate defined between first and second surfaces, a plurality of slot walls extending from the first surface, and a protruding edge that extends from a flanged lip and surrounds the plurality of slot walls. The retention plate defines a plurality of slots corresponding to the plurality of slot walls. The first housing may define a groove that receives the protruding edge, and the second housing may include a rim that engages the flanged lip of the valve retainer. Valve housings including first and second mating structures separated by wall segments may be positioned in outlets of the first housing and corresponding slots of the valve retainer.

Disclosed is a sensor arrangement on a process installation comprising at least two sensor tiles, wherein each sensor tile comprises a support and a plurality of sensors arranged on the support for determining a physical or chemical variable of a measuring medium, a process characteristic of the measuring medium, and/or a state of the process installation. A first sensor tile comprises a control unit having a transmit and receive module for data exchange with a control unit of a second sensor tile. The first control unit of the first sensor tile and/or a second control unit allocated to the sensor arrangement is designed to weight the values determined by each sensor tile. Weighting may be a function of the measured value variations of the sensor tile, the position of the sensor tile in the process installation, and/or the function of the sensor tile.

A fluid flow rate sensor, which may also be the basis of a valve for a fire suppression system, uses a sensing arm to convey motion of an obturation body or a valve closing member to a sensor system which evaluates the motion and generates a calibrated measure of the flow rate and/or an alarm signal in response if warranted. The obturation body and the valve closing member are capable of both rotation and translational motion, both of which are sensed using the sensing arm. The sensor system is isolated from the fluid within the valve.

A water management system effective for managing and metering water usage and detecting and reducing water leaks is described herein. The water management system can detect a leak when a volume of water flow or change in water pressure detected by a water meter of the system is uncharacteristic for a given day and time of day at the node. Upon detecting the leak, the system alerts the user, and in some situations, remotely shuts off a water supply to preemptively address a water leakage issue.
