Control 13 pumps with feedback pressure sensors

3 posts in this topic

Hi, I am building a 13 pumps system. Each pump has a pressure sensor (4-20mA output). All pressure setpoints are set from a touch screen. I wonder what solutions can be applied? - Simatic S7 Siemens - Twido, Modicon Schneider-Electric - .... Pls help me! Thanks.

My first idea would be : HMI -> multidrop connection to inverters -> inverters with PID control -> connect to pumps.

Beijer E-terminals have a driver for Mitsubishi Inverters
