Distance and Level Measurement in Industrial Applications (Set 3)
https://support.industry.siemens.com/cs/document/21689394/distance-and-level-measurement-in-industrial-applications- (set-3)
You would like to monitor the filling level of a storage tank which is to be filled automatically.
This application demonstrates by the following example how you can configure an automatic filling level monitoring based on LOGO! ...
When falling short of the minimal filling level (switching on limit) of the storage tank it shall be filled. When exceeding the maximal filling level (switching off limit) the filling cycle shall be stopped automatically.
The LOGO! base module is used as a controller for the automation solution.
An ultrasonic sensor is used for filling level monitoring and it is connected to an analog input at the LOGO! logic module.
The voltage signal of the ultrasonic sensor is evaluated in the LOGO! control program in order to regulate the filling level.
The switching on and off limits are displayed as a numerical percentage value on the LOGO! display.
The current filling level is additionally represented as a bar chart diagram.
The switching on and off limits can be configured via the LOGO! display.
The modes and the filling cycle can be operated via LOGO! cursor keys.
