Operating Manual - A5E00102775-03
In older versions of sensors the calibration constant is known as
”C100” and must be converted with the formula
CFH = ( 35343 * DN [ in m ]
2
) / C100
into a CFH value.
In probes the probe constant ”C1” must be converted with the formula
CFH = 1250 / C1
into a CFH value!
The ZPH value must be set to 0 in both cases!
Gas/air in the line If there is still gas/air in the measuring tube or in the pipeline after
assembly, a flashing “F” appears at the top of the first line in the display
(see also menu item ”
2.1 Device status” in section 3.2.1). The failure
signal is output at the analog output and for the digital outputs an error
message is output if they are programmed for this function. The flowing
medium removes the gas/air occlusions from the tag and the flow can
be measured without interference after a few minutes.
