1480698 Salt consumption indication apparatus LICENTIA PATENT-VERWALTUNGS GmbH 9 Oct 1975 [29 Oct 1974] 41453/75 Heading G1N An apparatus for determining the consumption of salt from the regenerator of an ion-exchange water softener comprises a salt storage chamber 3 divided into two parts 4, 5 by two partitions 14, 15, a water inlet 16, a salt solution outlet 9 and conductivity measuring electrodes 11, 12 in the inlet chamber. The dividers 14, 15 define an overflow passage 17 which may contain a non- return valve, as may outlet 9. In use, both chambers 4, 5 are filled with salt 6, 6' through filler openings 7. Water from inlet 16 will dissolve salt in chamber 4 first so that a saturated solution passes through chamber 5. When the salt 6 in chamber 4 is used up, the conductivity of the solution between electrodes 11, 12 rises and measuring circuit 13 activates a warning. The salt in chamber 5 still remains as a reserve. |
