(OP)
We have the pump curve( Flow Vs Head & Efficiency) given by OEM.
I want the system or software, which will have the curve installed. Also which will show me the online live values of flow, head and efficiency. So that i can know, which point i m operating the pump?
Here, the input data can be taken from PLC or SCADA.
Is there any vendor who develop these solution, or readymade system...?

RE: Online Pump curve developer
Centrifugal pumps are often adequately fit by the equation of a concave down parabola with vertex at zero flow and shut-off head. From there you can use the affinity laws to give you the entire family of curves with acceptable accuracy.

Kindly elaborate, in CURVE EXPERT PROF
How to input the data, from PLC or SCADA...?

I should have read your post more carefully. So, you want to input flow and capacity directly from SCADA and then build your own pump curve from it?
BigInch's suggestion would work.
Me, I would have read the data from the OEM curve, fit an equation to it, and programmed the equation.

RE: Online Pump curve developer
In your idea, we have to input the flow & head to develop the curve using that CURVE EXPRT. am i right...?
Hi BigInch, can i get the curve using PLC data...? if so, how..?
RE: Online Pump curve developer
You must know the pump curve, so draw those in Excel and tap the current operating point signals from either the PLC or SCADA, then show them on the same Excel graph as your pump curve. Don't forget to add current suction head to the curve.
