FLOWPULSE INSTRUCTION MANUAL

Step Response Threshold
The step response threshold is the change in flow required for the normal
damping to be bypassed. The range of the step response threshold is:
Min = 22, Max = 426.
Default = 60
400 relates to the ‘Flow High’ value.
The higher the step response threshold, the larger the jump in flow needs to
be before damping is skipped.
Step Change Limit
The step change limit is the maximum change in flow that the FlowPulse will
ignore the damping for. A change in flow greater than this limit will adhere
to the set damping.
Min = 22, Max = 426
Default = 119
Flow Low and Flow High
The “Flow Low” and “Flow High” parameters represent the minimum and
maximum flow rate setting, in units of volumetric flow rate.
By default, the flow rate limits, in units of litres per second, are set to
correspond to the specification of flow velocity range of 0 to 4 m/s (0 to
10m/s for high flow version).
Note that the mA output is scaled to the flow rate limits that are set here.
For example, if the range is set to Flow Low = 3 litres/sec and Flow High =
10 litres/sec, then the mA output will be 4 mA at 3 litres/sec and 20 mA at 10
litres/sec. Please refer to the “mA Output” section for more information.
