Flow; Configure General Flow Setting - MultiTrode MultiSmart Installation & Operation Manual

20 Flow

The flow module provides the ability to calculate flow without the use of a flow meter in most
empty/discharge applications. The flow menu can be used to assign and make changes to the configuration
of the flow input devices or to unassign the input device.
The Smart Outflow feature present in the flow module can detect a partially blocked pump from a large
inflow. The Time to Spill feature calculates and displays the time period within which a spill may happen if
the current conditions do not change.
The flow module also allows a flow meter to be used, either 4-20mA for instantaneous flow, a pulse counter
for totalized flow, or both.
The advantage of using the flow module when a flow meter is installed is the data appears on the Flow
section of the Info screens.
calculated, and flow rates are also apportioned to individual pumps.
In addition, the flow module uses specific flow tags, and when SCADA is used, these tags are available at
SCADA, providing a common tag structure across a network of pump stations.
The flow module also provides 2 low flow and 2 high flow alarms.
NOTE: After calculated flow is configured, one complete fill cycle and one complete empty cycle are
needed before any flow calculations show up in the Info page.

20.1 Configure General Flow Setting

To configure Flow settings go to:
The following parameters can be set:

NOTE: If the Units are changed, the existing flow statistics are not converted into the new units so a
reset of the flow statistics is recommended. (Navigate to: Info

Description
Enables or disables flow calculations for the station.
Sets the flow measurement mode.
The flow mode specifies whether the station outflow should be
calculated or measured using one of the following flow metering
methods:
Metered F & V uses an analog input for instantaneous flow (F)
and a pulse counter input for volume (V).
In Metered Flow mode, the flow module uses an analog input to
measure the flow, and derives the total volume, (if the flow rate
is <1 gal/sec or <1 litre/sec the total flow will not be
accumulated).
In Metered Volume mode, a digital input is used to count pulses
from a flow meter to measure the volume pumped, and
periodically it derives the flow rates.
Flow measurement units.
Efficiency measurement units
Enables overflow detection.
Sets the level at which an overflow condition is detected.
Sets how many pump cycles are used in the outflow averaging
calculations.Only used for Calculated and Metered Volume
(der.flow) Modes.
