UFM 3030 35
Function 3.03.09 Display date
Not available, reserved for future use.
Function 3.03.10 Display analog input
Enable/disable the display of the analog inputs.
Only available for converter functions CORR T and CORR T + P (see Function 3.02.01). The
display of the values represented by the current signal coming from the temperature- and pressure
transducers. See Function 3.02.02 through 3.02.07.
Function 3.03.11 Display gain
Enable/disable the display of the signal level from the sensors. For each measuring path this level is
displayed as a gain value 0 dBV through 80 dBV at the input amplifier.
Submenu 3.04.00 Current output
Function 3.04.01 Function of current output
The current output can be programmed for the following functions:
•
OFF switched off, current output steady at current value for 0 % scale, see Function 3.04.03
ACT FLOW proportional with the actual volume flow, see Function 3.01.0.1 FULL SCALE
•
CORR FLOW proportional with the corrected volume flow, only available if the converter
function is set to CORR T or CORR T + P (see Function 3.02.01)
•
F/R IND forward/reverse flow indication, see Function 3.01.10, 100 pct mA value for forward
flow, 0 pct mA value for reverse flow, see Function 3.04.03 through 3.04.05
•
VOS proportional with the velocity of sound, see Function 3.01.11 through 3.01.12
•
SIGN LEVEL proportional with the signal level, see Function 3.03.11
•
AN INP 1 proportional with the signal on analog input 1, see Function 3.02.01, Only available if
the converter function is set to CORR T or CORR T + P (see Function 3.02.01)
•
AN INP 2 proportional with the signal on analog input 2, see Function 3.02.01. Only available if
the converter function is set to the CORR T or CORR T + P (see Function 3.02.01)
Function 3.04.02 Direction of current output
Only available when ACT FLOW or CORR FLOW is selected in Function 3.04.01. When
FORWARD is selected, the current output will only be active when the flow is in the forward flow
direction as defined in Function 3.01.10 FLOW DIR, while when BOTH is selected, the current
output will be active forward and reverse flow direction. Use F/R SPEC to indicate the reverse flow
in the range from 0 mA through 0 pct mA (see Function 3.04.04 0 pct). I.e. when the flow goes from
the forward direction to the negative direction, the current output will pass the "0 pct" mA value
down to 0 mA, where it stops.
