Prestop Quantity Sets the point near the end of the load at which the flow will switch from
Valve Low Flow The minimum flow rate throughout a batch.
Valve Response Valve response is a measure of the magnitude of adjustment made to
Auto High Flow When enabled, if the actual flow rate does not reach the target flow rate
Valve Full Flow Sets the desired flow rate when full flow is required. Flow is set to full
High Flow Timeout The time allowed for the actual flow rate to reach the target flow rate
7 - 2
(Minimum Linear Flow Rate + Dead Band) to 800 (300*)
high to low. A low flow at the end of the load helps prevent pipe stresses
and gives a more accurate cut-off.
Enter a value in the following range:
0 to 999 (300*)
Constraints: None
Enter a value in the following range:
(Minimum Linear Flow Rate + Dead Band) to 800 (300*)
the flow control valve. A value of 0.2 results in a slower change of flow
rate than a value of 1.
Constraints: Only for Valve Type = Digital.
Enter a value in the following range:
0.2 to 1.0 (0.7*)
within the High Flow Timeout period, the target flow rate is reduced by
the deadband and the High Flow Timeout is restarted. This sequence
continues until the target flow rate matches the actual flow rate allowing
for the dead band setting.
Once the reduced target flow rate has been achieved and has been
stable for the high flow timeout period the instrument will then try
increasing the flow rate. For more details see the Software Manual.
Constraints: Only for Valve Type = Digital.
Select one of the following options:

flow rate after the start time has elapsed, and remains at this flow rate
until the delivered quantity has reached the preset less the pre-stop
quantity.
Constraints: Only for Valve Type = Digital.
Enter a value in the following range:
(Slow Flow) to 9999 (1800*)
before the target flow rate is reduced by the deadband.
