Sensor zum Messen des Niedrigstandes von Salz.

摘要

A low salt level sensor comprising a float (24) within a brine tank (10), means for detecting whether said float (24) has risen in response to the addition of a predetermined amount of water (12) to said brine tank to a height such that an adequate supply of salt (14) is present in said brine tank (10) and means for indicating if the float (24) has not risen high enough. A method of detecting whether the salt level is low in the brine tank of a water treatment system is also described. According to this method, brine is removed from the brine tank and a predetermined amount of a water is added. A determination is then made as to whether the brine level has reached a height such that an adequate supply of salt is present in said brine tank and an indication is provided if the brine level is below this height.
