  • Apparatus with a self-cleaning electrode for sensing at least one parameter in water
    Patent number: 9816962
    Abstract: Apparatus (2) for sensing at least one parameter in water, which apparatus (2) comprises: (i) at least one electrode based sensor (4, 6) for sensing at least one parameter in water; and which apparatus (2) is such that: (ii) the electrode based sensor (4, 6) has a self-cleaning electrode; (iii) the electrode based sensor (4, 6) has a reference electrode; (iv) the self-cleaning electrode is stable in water; (v) the apparatus (2) is configured to operate by liberating chlorine from the water using a first waveform applied to the self-cleaning electrode; (VI) the apparatus (2) is configured to operate by liberating chlorine and oxygen from the water using a second waveform applied to the self-cleaning electrode; and (VII) the apparatus (2) is configured to preserve the condition of the reference electrode by periodically regenerating the reference electrode.

  • Process for sensing at least one parameter in water
    Patent number: 9448200
    Abstract: Apparatus (2) for sensing at least one parameter in water, which apparatus (2) comprises: (i) a dissolved oxygen sensor (4) for sensing dissolved oxygen in the water; and which apparatus (2) is such that: (ii) the dissolved oxygen sensor (4) has a working electrode and a reference electrode; and (iii) a voltage signal is applied between the working electrode and the reference electrode, and the voltage signal provides a conditioning waveform, then a wait time, and then a measurement function.
