Flow Alarms - MultiTrode MultiSmart Installation & Operation Manual

20.5.1 MultiTrode Probe
If using a MultiTrode probe as the primary level device, enter the volume of liquid between each sensor into
each of the volume fields. Since there are 10 evenly spaced sensors, the percentages will range from 10 –
100% in equal increments. If feet or metres has been set as the level units (see section 14.8), then the
configuration display will change accordingly.
20.5.2 Analog Level Device
If using a 4-20mA Level device, then the percentage values can be altered to reflect any volumes required to
be entered.
For example, in a 5m well, the lead/duty pump may be set to start at 1.5m (from the bottom) and stop at
0.5m. In this case, the activation point is 30% and the deactivation point is 10%. Setpoints may change, and
the level may rise above the activation point, therefore the volumes should ideally be set to 10%, 15%, 20%,
25%, 30%, 35%, 40%, 60%, 80% and 100%. The volumes for each step will then have to be calculated and
entered.

20.6 Flow Alarms

Flow warnings and faults are used to indicate when flow rates fall outside acceptable limits. To select and
configure alarms, navigate to:
Figure 152 – Configuring Flow Alarms
The first step is to enter a Nominal Flow Rate for the well. All the alarms are defined as percentages of this
rate. The rate is expressed as litres/second, litres/minute or gallons/minute depending on the Unit
configuration made in the General Settings screen.
In a similar manner, Low Flow alarms can also be configured for the station; enter the minimum Flow Rate.
All the alarms are defined as percentages of this rate.
Select and enable an alarm by pressing the Toggle button. When finished, press the Save button.
The basic fault parameters such as activation delay, deactivation delay, pump context and fault reset method
can be modified by navigating to:
Select the appropriate fault and then press Configure.
