each input labeled 1 through 2. Make sure that you select the type of device that is actually wired to that
terminal of the card!
Not Used should be selected if nothing is attached to that input.
Contacting Flow Meter should be selected if a low frequency (10 Hz maximum) contacting-head
water meter is connected to that input. These are generally reed switch sensors that give one dry contact
closure every gallon or more of volume through the meter. . A sensor of this type must be connected to
Digital Input 1-4.
Paddlewheel Flow meter
should be selected if a high frequency (greater than 10 Hz) Hall Effect
paddlewheel flow meter is connected to that input. This option will give you the ability to specify a K
Factor to convert contact closures into a flow rate. A sensor of this type must be connected to Digital
Input 1-4.
Generic Input
should be selected if the digital input state (open or closed) will indicate an alarm
condition or if the input state needs to be logged. The WebAlert allows you to specify a custom
message to be delivered if the contact is open or closed. A sensor of this type can be connected to any
Digital Input.
Generic Counter should be selected if the contact closure from the sensor will be used to log counts
and/or to initiate a relay to activate for a given time after a given number of counts. . A sensor of this
type must be connected to Digital Input 1-4.
