| 摘要 |
The invention comprises an electrolytic scale inhibitor (100) comprising: an inlet (101); an outlet (102); a chamber disposed between the inlet (101) and outlet (102) through which a fluid can flow; a first conductor formed from a first material; a second conductor formed from a second, different material with a lower standard electrode potential than the first material; and an electrical link between the first and second conductors, wherein when the chamber is full of fluid, the first and second conductors are each in contact with said fluid and wherein the link between the first and second conductors is provided with a monitoring means that is operable to determine a component of the electrochemically generated current flowing therethrough that arises from the difference in the standard electrode potentials of the first and second materials and to output a signal indicative thereof. Also proposed is a method of determining whether an electrolytic scale inhibitor is functioning adequately. |
