CALIBRATION METHOD FOR TURBINE FLOW METER

摘要

The present invention provides a fluid flow meter that generates pulses proportional to the flow therethrough, both at high flow rates and low flow rates, the meter being at least temporarily in fluid connection with a further means for determining the actual flow rate through the flow meter, whereby the time between pulses can be calculated and a graph of time between pulses versus volume per pulse can be generated for each specific meter, enabling the creation of a table having discreet O order and first order curve regions with the characteristics of the specific meter which can then be downloaded into the specific meter when operating in any one of the specific predetermined regions and thereby enabling an accurate calculation of volume per pulse and hence flow rate for the specific meter.
