7. Flow Meters
7.1 Flow Meter Setup
VERIFY ALARM -
If a flow meter is linked to a control relay, the controller will give an alarm if it does not receive a
contact or pulse from the aux meter within the amount of time defined, or if it gets a contact when the relay is not on.
RELAY LINK - The relay link informs the Aux meter input is relevant to the control function that the selected
relay is being driven by. For example, if the Aux flow meter is a metering pump's FloTracker then it should be
linked to the relay that is driven by the feed timer that pump will be controlled by. If the Aux meter is going to
be linked to a water meter in a bleed-off line then it should be linked to the relay that is controlling the bleed
off valve.
VOLUME ALARM - If FloTracker has been selected as the Tracking method, an alarm will occur when the
defined VOLUME USED has passed through the flow device.
Note: If Rate and Volume tracking has been selected an alarm will occur if the defined MAX VOLUME
amount is measured within the defined TIME CYCLE which can be a 12- or 24-hour period.
RESET VOLUME - Resets the Volume Alarm totalizer.
METER LINK – This selection only shows if the tracking method is Rate and Volume and tells the auxiliary
flowmeter input to get its signals from one of the system water meters already wired to the controller's water
meter inputs. If this is selected, no wiring to the auxiliary input is required and the PULSE VALUE and UNITS
settings are auto populated from the water meter's settings.
TRACKING - Provides a pop-up screen to select either FloTracker or Rate and Volume tracking.
A unit may have up to 10 option auxiliary flow meter
inputs. These additional inputs are for tracking
various flow meter devices like Advantage Controls'
6
FloTracker in a metering pump's discharge tubing.
They can also be linked to a system's water meter
7
input for additional tracking and alarm capabilities.

The Flow Meter setup gives the user access to the
various settings for the flow meter along with a review
of the current settings.
PULSE VALUE - Defines the numerical value for a
contact, i.e. 225.
UNITS - Defines the units of measure for a contact,
i.e. Pulses / Ounce.
RESET TOTAL - Resets the totalized count of the
meter.
