Answer / greenborhan

1. Pressure switch used on pressure line/process line (pipe) to save the line/process from over pressure.
2. Level switch used on Drum/tank/vessel to see the level of the drum/tank/vessel.
3. Flow switch used the line through which fluid/liquid/air/gas is flowing, it confirms that if there is any flowing elements or not.

Input of all these switches are +24VDC and output of these are Digital Signal, these switches send a Digital Signal/Input to DCS.
My answer is right or wrong?? I am a little bit confuse...
