Example:
You expect a maximum flow rate of 100 m3 in your application and assigned this rate the 20
mA value. You also set the following defaults for the error mode
If an error is pending, the 4 mA to 20 mA output enters the error mode and outputs 4 mA on
expiration of a delay time of
20seconds. In practical operation you may have a flow rate of
130 m³ in the piping for a duration up to
two minutes. In this case, your deltawaveC-P
would output 20 mA for the duration of
20seconds and then enter the error mode and
output 4 mA on expiration of a timeout of
20seconds. After the flow rate has dropped again
