Problems solved by technology

[0015] The problem with known devices is that when one of a limited number of specific conditions does not occur, the fact that the hardness value itself may not be correct because the water softening device may not conform to the ideal model on which conductivity based hardness calculations are based

Embodiment Construction

[0112] As an example of a liquid handling system, a system for softening water ( figure 1 ) includes an inlet 1 for connection to a source of untreated water. The water source may be, for example, a tap water source. The system comprises an outlet 2 for connection to an appliance (not shown) or a conduit leading to the appliance to supply the appliance with water of a suitable hardness level. The system can of course be configured to supply water to more than one appliance. First and second fluid paths pass through the system between the inlet 1 and the outlet 2 .

[0113] Untreated water entering the system through the inlet 1 is directed to a variable ratio flow divider 3 where the first and second fluid paths diverge. The first fluid path passes through a liquid treatment component 4 configured to remove to some extent minerals contributing to temporary hardness or carbonate hardness from water passing through it.

[0114] Said liquid treatment unit 4 comprises a bed of...

Abstract

Method for processing data of a system for controlling the hardness of water. A sensor (12, 33, 57) measures a parameter related to the hardness of the treated water (e.g. the conductivity). A processor receives the sensor data and decides whether or not to pass on a signal related to the parameter to further process. This ensures that incorrect hardness readings, such as data recorded right after the exchange of the ion exchanger cartridge, are not transmitted to a further process. Alternatively, an integral value (e.g. the total amount of water processed since the last cartridge change) is taken into account and the sensor data is adjusted.

Description

technical field [0001] The present invention relates to a method of processing data acquired by operating a liquid handling system comprising a liquid handling component comprising at least one liquid handling medium, the method comprising: [0002] receiving a measurement signal, the value of which is indicative of a first parameter, which is a parameter of the liquid which is dependent in part on the liquid being removable by said liquid treatment part from liquid flowing through said liquid treatment part, at least to some extent. The concentration of at least one component of , [0003] wherein said signal is a signal originating from a sensor located downstream of said liquid handling component; [0004] determining a value of a measure of the concentration of a component removable by said liquid treatment component based at least on a corresponding value of said measurement signal; and [0005] determining the value of at least one second parameter, each second paramet...
