Automatic level control is achieved through variable frequency operation of the outlet pump

Who has such a PID? Upload it, please. The liquid level of a device is automatically regulated by adjusting the frequency of the pump connected to its outlet
Which sea friend can help? Looking forward to your assistance
There are no ready-made diagrams; essentially, it’s sufficient to connect the line that was originally used to connect the control valve to the pump. As for the control method, treat the variable-frequency pump as a control valve.
It can be fully achieved using PLC control, along with a corresponding level gauge
Hehe, is it connected to the pump body? Personally, I think the proper way of representation shouldn’t be that simple.
A simple drawing along with a connection to the pump body is sufficient; sometimes a circle is drawn and “VVVF/Tag Number” is indicated inside it. However, it needs to be designed in detail in the automation and electrical professional drawings.
Thank you! Could you take a screenshot and send it?
