- the spray device 10 may also have only one sensor unit 68, 70, for example the sensor unit 70 in the spray nozzles 46, whereby the flushing process can also be monitored and optimized. The rinsing process is started manually.
- control device 72 is set up, a property signal 74 having a signal by means of the sensor unit 70 of the spray device
- control device 72 is furthermore set up to record at least one further property signal 78 with a signal detected in the flow region 73 by means of the sensor unit 68 of the spray device 10
- Property information 76, 80 each include an electrical Conductivity and a temperature of the rinsing liquid 54. Accordingly, the sensor units 68, 70 each have a sensor for detecting the electrical conductivity and one for detecting the temperature.
- the control device 72 is also set up, an information signal 82 to a display unit 84 and / or a control signal 86 to the rinsing unit 56 in dependence on the
- Control means 72 arranged to compare by means of a computing unit 88 at least one value of the property information 76, 80 of the rinsing liquid 54 with at least one predetermined reference value and / or a predetermined reference value range of the property information 76, 80, in response to the information signal 82 to the display unit 84 and / or output the control signal 86 to the flushing unit 56.
- the arithmetic unit 88 is further configured, using the property information 76, 80 to determine an active agent concentration in the rinsing liquid 54.
- the control signal 86 is output, in particular, when the property information 76 has reached the reference value and / or reference value range. In this case, the control signal is designed to deactivate the purging unit 56 to the
- the control device 72 also has a
- Memory unit 90 for storing the property information 76, 80, the detected values and the reference values.
- 3 shows a flowchart of a method 100 for monitoring and / or controlling a rinsing process carried out by means of a rinsing liquid 54, in particular a rinsing water 54, in a spraying device 10 for dispensing a spraying liquid 36 having an active agent 18,
- the method 100 comprises a step 102 of receiving at least one property signal 74, 78 with one by means of a sensor unit 68, 70 of the spray device 10 in one
- Property information 76, 80 of the rinsing liquid 54 wherein using the property information 76, 80 an agent concentration in the
- Rinse liquid 54 can be determined.
- the method 100 finally includes a
- method 100 further includes a step 104 of comparing at least one value of
- an exemplary embodiment comprises a "and / or" link between a first feature and a second feature, this is to be read such that the
- Embodiment according to an embodiment both the first feature and the second feature and according to another embodiment, either only the first feature or only the second feature.
