A remote pump manager system equipped with pressure sensors, flow sensors, power meters, and a programmable logic controller that automatically determines and displays pump efficiency data in real-time, and can send this data to a remote server for further analysis and potential remote control of pump functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If pumps are not actively monitored, then device complexity is reduced, but pump efficiency deteriorates and energy waste increases
Solution Approach 1:
The pump system performs self-monitoring through integrated sensors and controllers that automatically track operational parameters without requiring external monitoring infrastructure. The pump controller collects data from pressure sensors, flow meters, and power meters, calculating efficiency metrics autonomously
Solution Approach 2:
The pump controller serves multiple functions simultaneously: it controls pump operation, monitors operational parameters, calculates efficiency metrics, and communicates with remote systems. This multi-functionality eliminates the need for separate dedicated monitoring equipment, reducing overall system complexity while maintaining high pump efficiency
2Productivity
If real-time monitoring is implemented, then pump efficiency is improved, but use of energy increases due to additional sensors and controllers
Solution Approach 1:
The monitoring functions are merged with the existing pump controller rather than using separate dedicated monitoring equipment. Pressure sensors, flow meters, and power meters are integrated into the control system, allowing efficiency calculations to be performed using the same computational resources already allocated to pump control operations
Solution Approach 2:
The system implements feedback loops where sensor data is continuously fed back to the controller, which automatically adjusts pump operation to maintain optimal efficiency. This closed-loop control ensures that the energy invested in monitoring directly translates to energy savings through optimized pump performance
3Measurement precision
If periodic pump tests are performed manually, then measurement precision is reduced, but loss of time increases due to manual intervention requirements
Solution Approach 1:
Manual mechanical testing procedures are replaced with automated electronic monitoring and calculation systems. The controller continuously collects operational data from integrated sensors and automatically calculates efficiency metrics, eliminating the need for manual testing interventions while maintaining or improving measurement precision through consistent automated data collection
Solution Approach 2:
The system transitions from periodic discrete testing to continuous monitoring, where efficiency parameters are constantly measured and tracked. This continuous action provides ongoing precision measurements without the time losses associated with setting up and executing manual periodic tests, as the monitoring occurs continuously during normal pump operation

AI summary
A remote pump manager is provided. The remote pump manager includes pressure sensors or a depth sensor operating to determine the change in pressure of a pump, a flow sensor operating to determine flow rate of fluid exiting the pump, a power meter operating to determine power data related to operation of the pump, and a management device having a programmable logic controller and a display. The pressure sensors, the flow sensor and the power meter are in communication with the management device. The management device operates to determine pump efficiencies, wherein the programmable logic controller automatically determines pump efficiency data in response to receiving real time data from the pressure sensors, the flow sensor and the power meter and automatically delivers the pump efficiency data to the display for displaying the determined pump efficiency data.
