Calibration
There is a (calibration) factor betw een the real flow velocity and the flow velocity displayed by the
device. This calibration factor can be determined by carrying out a calibration. How ever, you will need
flow calibration equipment to do so.
Please send the device to PCE Instruments for calibration. Our contact details can be found at the end
