Abstract
A sensor is configured to sense a parameter of an aqueous liquid. The sensor has an analog output port configured to provide an analog signal indicative of a sensed parameter, and a calibration memory device storing individual digital information indicative of a calibration of the sensor. A digital output port provides a digital signal indicative of the digital information. A treatment system and method is matched to the sensor.

A treatment system for treating an aqueous liquid comprising:
- a conduit for channeling the aqueous liquid to be treated;
- a treatment device associated with the conduit for altering a parameter of the aqueous liquid and having an input port for receiving a treatment signal indicative of an extent to which the treatment device alters the parameter of the aqueous liquid;
- a first sensor sensing a parameter of the aqueous liquid and having an analog output port providing an analog signal indicative of the sensed parameter, said first sensor having a calibration memory device storing digital information indicative of a calibration of the sensor and having a digital output port providing a digital signal indicative of the digital information;
- a second sensor comprising a temperature sensor for sensing a temperature of the aqueous liquid and having an output port providing a temperature signal indicative of the sensed temperature;

- a controller having a digital input port connected to the digital output port of the first sensor, said controller receiving the digital signal via its digital input port and determining a calibration of the first sensor,
- said controller having an analog input port connected to the analog output port of the first sensor, and an input port for receiving the temperature signal from the temperature sensor;
- said controller receiving the analog signal from the first sensor via its analog input port, and determining the temperature of the aqueous liquid based on the temperature signal, and determining a temperature-adjusted parameter of the aqueous liquid based on the received analog signal, the received temperature signal, and based on the received digital signal,
- said controller having an output port connected to the treatment device providing the treatment signal to the input port of the treatment device, said treatment signal configured to control the treatment device as a function of the determined temperature-adjusted parameter by controlling the extent to which the treatment device alters the parameter of the aqueous liquid, and wherein
- said treatment signal provided by the output port of the controller is configured to control the treatment device as a function of the determined temperature-adjusted parameter of the aqueous liquid as compared to a minimum free parameter level by controlling an amount of a substance that is added to the aqueous liquid by the treatment device or a rate at which the substance is added to the aqueous liquid by the treatment device, wherein the substance can alter the parameter of the aqueous liquid.
