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. TIA
