Use to scale the external sampler up or down as required.
Values
Range: 0.0000001 to 99999
.000
Default: 1.000
This allows the totalizer relay to click for different values of volume.
Example:
To click once every 4310 units, set 2.11.4.2. Multiplier to 4310.
Interval (2.11.4.3.)
The time in hours from the activation of the relay until the next activation.
Values
Range: 0.1 to 99999
.00
Default: 1.00
Set the time to activate the relay during low-flow conditions.
Relay Duration (2.11.4.4.)
The time in seconds from one change of state in the relay to the next.
Values
Range: 0.1 to 1024.0
Default: 0.2
This value must be less than the Interval (2.11.4.3.) (Page 217) or the relay will never reset.
Assigned Relay (2.11.4.5.)
Determines the relay assigned to flow sampler control.
Options
*
RELAY 1

NORMALLY OPEN
NORMALLY CLOSED
Relay contact operation is NORMALLY CLOSED for alarms and NORMALLY OPEN for
controls.
By default a control contact is Normally Open. For Interval (2.11.4.3.) (Page 217) the
corresponding relay coil is energized. By setting this parameter to
Normally Closed, the relay
coil will be de-energized for the duration phase.
