Appurtenances added to a pipe mitigate the effects of upstream valves, sluice gates or pipe elbows to condition the pipe flow for accurate flow rate detection by a reverse propeller meter. Further appurtenances allow the reverse propeller meter to be used in extreme debris situations such as weeds, vines and moss present in many canal systems. The system provides an electronic signal that indicates flow rate and accumulated flow volume, or the signal can be transmit to a central headquarters for remote gate control or canal automation.

A flow imaging and monitoring system for synchronized management of wide area drainage that includes an interposer for supporting monitoring and management equipment in a manhole, a module for illuminating water flowing in pipes at the base of the manhole, a module for monitoring responses to reflected light, a sealed and rechargeable battery pack, and a data analysis and management system to interpret data streams in real time. The interposer can be adjusted to fit the diameter of the manhole and can be adjusted to be placed under the manhole cover. The module for illuminating the flowing water can be adjusted to generate various frequencies. The support structures for the modules can be adjusted for varying pitch, roll and yaw with respect to the manhole. The data analysis and management system is supported by cloud computing.

A pump system has at least one fluid container (2) which comprises an inlet (4) and an outlet (6), at least one pump (8) arranged in the inlet (4) or the outlet (6), and a control device (16) which includes a flow evaluation device for determining a flow through the fluid container (2) of the pump system. The flow evaluation device is configured such that the flow evaluation device uses a system model for determining the flow. The system model includes at least two different sub-models, a sub-model which describes the inflow behavior of the fluid container (2) and a sub-model which describes the outflow behavior of the fluid container (2). A corresponding pump flow evaluation method is provided.

An analysis tool for monitoring and displaying the real time and historical hydraulic conditions in a sewer system as measured by monitors distributed throughout the sewer system and associated weather data. Data about the hydraulic conditions of the sewer system are displayed in a graphical display that incorporates a visual representation of the sewer system infrastructure.

A treatment structure for rainwater has at least one receiving vessel for rainwater and an outlet for discharging treated rainwater. A monitoring device for monitoring a need for maintenance of the treatment structure is provided. The monitoring device has at least one first sensor for detecting a fill level of rainwater in the vessel, at least one second sensor for detecting an amount of precipitation in a predetermined area surrounding the treatment structure, and at least one data processing unit in which parameter values from a group comprising a predetermined target fill level and a predetermined target rate of decrease of the fill level of rainwater in the vessel are stored. Here, the at least one first and the at least one second sensor are operatively coupled to the data processing unit via an electronic data line.

A system and method for measuring or for estimating flow or flowrate of a fluid, including wastewater inflow or infiltration, using non-contact depth-based flow measurement, including: receiving a depth sensor signal from an ultrasonic depth sensor positionable over a manhole channel above an outgoing pipe's crown; receiving a temperature signal from a temperature sensor positionable within the manhole channel; receiving one or more data input signals; calculating a distance to a surface of the fluid based on the received depth sensor signal; and determining a depth of the fluid in the manhole channel based on the calculated distance. Flow velocity may be calculated using Manning's equation or the Hazen-Williams equation, with flow rate subsequently determined using the continuity equation. Alternatively, flow velocity and flow rate may be estimated using a machine learning model trained on simulated or historical time-series data of flow rate, flow velocity, and flow depth, along with pipe attributes, to generate real-time flow estimates based on current and prior flow depth measurements.

Systems and methods are disclosed for controlling a fluid-flow network transport infrastructure using distributed field devices. A control system applies a fluid-flow control policy to configure operational modes for a plurality of field devices. Each field device is configured to monitor fluid-flow parameters and report sensor data based on dynamic criteria. Upon receiving an alert from a field device, the system identifies other field devices that are hydrologically or hydraulically connected to the alerting device and satisfy a defined proximity threshold. Activation commands are issued to prompt additional data collection. The system manages fluid-flow control devices, such as valves or pumps, based at least in part on received sensor data, policy criteria, and environmental inputs. A simulated digital counterpart can model expected system behavior and inform adaptive policy adjustment. The disclosed architecture supports condition-responsive monitoring and decentralized control, reducing energy consumption and enhancing real-time responsiveness.
