Abstract
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. A solar heating system includes the pump system.
Claims17
A pump system comprising:
- a pump comprising a pump housing defining at least one flow path for a liquid, the at least one flow path being located inside the pump housing;
- a concentration measurement device measuring a concentration in the liquid inside the flow path, wherein the concentration measurement device comprises a sensor arranged in or at the flow path, and a further signal source providing at least one further parameter and an evaluation device configured to evaluate the sensor readings, wherein:
