Solution Overview
Problem
Existing pump systems face challenges in accurately detecting liquid properties, such as concentration, under various operational conditions, leading to imprecise measurements.
Innovation Solution
A pump system equipped with a concentration measurement device that includes a sensor and an evaluation device, which considers additional parameters from further signal sources to compensate for operational conditions, ensuring precise concentration detection.

Engineering Contradiction Analysis
1Measurement precision
If a concentration sensor is used to detect liquid properties in a pump system, then concentration measurement capability is provided, but measurement precision deteriorates under varying operational conditions
Solution Approach 1:
The evaluation device receives signals from both the concentration sensor and additional sensors (temperature, flow, pressure) and uses this feedback to compensate for operational condition variations. The system continuously monitors multiple parameters and adjusts the concentration evaluation based on the additional sensor inputs, thereby maintaining measurement precision across varying operational conditions.
Solution Approach 2:
The system changes the parameters being measured by incorporating additional sensors that detect temperature, flow rate, and pressure. These additional parameters are used to compensate for the concentration sensor's readings, transforming a single-parameter measurement system into a multi-parameter evaluation system that maintains accuracy under varying conditions.
2Measurement precision
If additional sensors and signal sources are integrated into the pump system, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The evaluation device serves as a central integration point that combines signals from the concentration sensor with additional sensors (temperature, flow, pressure). By merging these multiple sensor inputs into a single evaluation unit, the system achieves improved measurement precision without proportionally increasing overall system complexity. The evaluation device processes all inputs together to produce a compensated concentration reading.
Solution Approach 2:
The evaluation device is designed with multi-functionality, serving both as the primary concentration measurement processor and as the integration point for additional sensor signals. This universal component handles multiple functions (concentration evaluation, temperature compensation, flow compensation, pressure compensation) within a single device, thereby reducing the need for separate processing units and minimizing the increase in system complexity.

AI summary
A pump (2) system includes a pump, a sensor (22; 28) arranged in or at a flow path (14), and a concentration measurement device measuring a concentration in liquid inside the flow path (14). The concentration measurement device includes the sensor (22; 28), as a concentration sensor, connected to an evaluation device (26) for evaluating readings of the sensor (22; 28). The evaluation device (26) is connected to a further signal source (20; 24), providing at least one further parameter, and is configured to carry out an evaluation of the reading of the sensor (22; 28), taking into account the further parameter provided by the further signal source (20, 24) to output the concentration in the liquid.
