Operation - Calibration
The pulse phase parameter on the screen provides the phase
difference between the quadrature pulse inputs used for the product.
It can be used to determine if phase relationship is forward, reverse
or inverse.
5.18 Calibration
5.18.1 Why Calibrate?
A flow meter provides a number of pulses per amount of fuel that
passes the meter. The number of pulses per unit of volume the meter
provides is called K-factor. This K-factor is specified per delivered flow
meter, by the manufacturer.
To increase the accuracy of the flow meter, a calibration process can be
performed. This process is performed by comparing the actual resulting
fuel volume received in a calibrated vessel (see FIGURE 5-34) with the
