All open-channel flowmeters require a 32-point flow curve, for calibration and commissioning + enabling accurate flow measurement.

We supply 32-point flow curves for all of our supplied flumes, weirs + complete open-channel installations.

We can also supply 32-point curves for existing primary devices, all we would need is the primary device + channel dimensions.

Please note, should the primary device be found to be the incorrect type for the application, we will not issue a 32-point curve, but rather a correct solution.
