Using SLC5/03 & RS Logix.
I have a pump that pumps water at about 5 litres a minute. The flow is
measured from a DP cell across an orifice plate. The 4-20 mA signal from the
DP Cell is linearised by the square root function in the plc program.
How can I take the linearised flow signal and give me a readout of pump
flowrate and total flow within the plc. I only want the readings in the RS
logix program and not to an external device. The readings need to be in
engineering units litres per minute & total litres.
