Gravimetric level measurement with SIWAREX U in the PCS 7 environment
Dosing and weighing operations are often required in process automation. Different methods are used depending on the requirements of the process.
Each method requires electronic weighing systems that vary according to the required task.
The SIWAREX FTA and SIWAREX U have been approved for use in the PCS 7 environment as an electronic weighing system.
In the process industry, a common use of the electronic weighing system is the gravimetric level measurement of a storage silo.
The gravimetric level measurement should be, as much as possible:
- precise enough
This Application Example allows us to describe the application of a gravimetric level measurement in the PCS 7 environment. The level of a storage silo should be monitored during the process.
In this process, the following requirements are imposed on the solution:
- The level of the storage silo is detected gravimetrically (by weight), and transmitted to the control system
- The HIGH and LOW limits are defined in the AS and are evaluated
- Display of the current level locally by means of a simple display
- Zero setting of the scale, e.g. in case of contamination
The current Application Example provides a template that comprises all typical components, their control system and the necessary logic.
The following configuration example enables you to significantly reduce your engineering effort when using PCS 7 standard agents while improving performance. You can use this solution for both new configurations as well as for integration into existing projects. The required hardware and software products are all made by Siemens and guarantee the compatibility, actuality and upgrade options you are accustomed to.
When using the SIWAREX U - Advanced Process Library you also get the following benefits:
