How PLC controls a Valve based on Flow Meter?

Hi everyone, I am a student learning about PLC for the steam flow meter. I don’t know how to get a steam flow signal into the PLC and read it. Then, based on the steam flow, the PLC will control the valve on and off.

Please guide from everyone. Thank you!
