20150297056 | Alarm Unit For Dishwashing Systems - A method for sequentially monitoring a level of a sanitation agent comprises the step of providing a supply tube having a first portion and a second portion. The method includes the step of linking the supply tube first portion and the supply tube second portion with a pipe. An optical sensor is situated adjacent the pipe, and is used to take a reference reading and a fault check reading. A controller imposes a warning signal when a difference between the reference reading and the fault check reading is greater than a threshold. The reference reading is taken when the sanitation agent is in direct contact with the pipe. | 10-22-2015 |
20140048139 | Alarm Unit For Dishwashing Systems - A method for monitoring a level of a sanitation agent in a dishwashing system having a sanitation agent supply vessel includes the step of providing a supply tube having a first portion and a second portion that are unconnected to one another. The first and second portions are linked with a pipe. An optical sensor is situated adjacent the pipe, and a reference reading, a fault check reading, and a fault confirmation reading is sequentially taken with the optical sensor. The method further includes the step of imposing a warning signal by a controller when both: (1) a magnitude of the difference between the reference reading and the fault check reading exceeds a threshold; and (2) a magnitude of the difference between the reference reading and the fault confirmation reading exceeds the threshold. | 02-20-2014 |
