CALIBRATION
The menu makes it possible to determine the K factor of the process:
either by entering the value of the K factor of the fitting (depending on the pipe diameA ter and material, see instruction manual of the fitting S020): the transmitter then calculates the K factor for the process using the fitting K factor, the cell constant Fs and the
temperature coefficient Kw. Fs and Kw are set ex works and can be read and modified
within the TEST menu.
B
or by using the “TEACH-IN” procedure. It consists either of a volume measurement or
a comparison measurement with another flow meter.
The value of the K factor taken into account for the process is the last
determined K factor, whatever the method used.
