The K factor of the fitting used can be entered here. The device may also determine the K factor using a teach-in procedure: see "Fig. 58". The K factor of the fitting used is in the operating instructions of the fitting. The operating instructions of the Bürkert fittings can be found on the CD delivered with the device or on the internet at: www.burkert.com.

Type 8025 / 8035 operatingandcommissioning 9.6.4. configuring the current output The 4-20 mA output provides an electrical current, the value of which reflects the flow rate measured by the device. Example of relation between the measuring range and the current output: l/min → To invert the output signal, give a lower flow rate value to the 20 mA current value than to the 4 mA current value. → To disable the current output, set both range bounds, 4 and 20 mA, to zero. In this case the output delivers a constant current of 4 mA. The units and number of decimal digits are those set within the "UNIT" parameter for the display of the current output values. ENTER CURRENt 4=0000 → Enter the flow rate value related to the a 4 mA current, in the unit chosen in the 0..9 "UNIT".parameter. 4 = 28.00 20=0000 → Enter the flow rate value related to the a 20 mA current, in the unit chosen in the "UNIT" parameter. 0..9 ENTER PULSE 20 = 6.000 Fig.
