AUTOMATIC DETERGENT DISPENSING SYSTEM FOR A WAREWASHER
An apparatus dispenses detergent into a warewasher from a reservoir (50) wherein a flow control device (54) controls the flow of the detergent. A sensor (42) measures the electrical conductivity of water within the warewasher (10) and produces a conductivity measurement. A controller (32) operates t...

Summary: | An apparatus dispenses detergent into a warewasher from a reservoir (50) wherein a flow control device (54) controls the flow of the detergent. A sensor (42) measures the electrical conductivity of water within the warewasher (10) and produces a conductivity measurement. A controller (32) operates the flow control device (54) in a first mode in which the quantity of detergent dispensed into the warewasher (10) is determined in response to th e electrical conductivity of the water. If the conductivity measurement is determined to be unreliable, the controller operates in a second mode in whi ch a predefined quantity of detergent is dispensed into the warewasher (10). Th e reliability of the conductivity measurement is determined based on the amoun t that the conductivity changes upon detergent being added to the warewasher.< /SDOAB> |
