Fig. 24 Behaviour of the current output
The current output behaves as shown in the figure above.
Above the low flow, the current curve proceeds as a straight line in accordance with the flow rate.
-
Flow rate = 0, current output = 4 mA
-
Flow rate = Q
max
, current output = 20 mA
If the low flow cut-off is activated, flow rates below the low flow are set to 0 and the current
output set to 4 mA.
