Operation
Examples
NOTE: In the following examples it is assumed:
D Meter-mounted Informer package (243312) is used
D Default K-factor of 0.12 cc/pulse is accurate
D External power supply is used
D Jumper JP2 is set to position 1–2, all other jumpers
and setup parameters not specifically mentioned in
the example, are assumed to be in the default
position or setting
Example 1: Gun Flow Rate Detection
The informer is used to monitor the flow rate through a
gun. If the gun tip is plugged, the flow is restricted and
the flow rate is reduced. If the gun tip is worn, the flow
rate through the gun is increased.
A power supply is used to power the Informer and the
alarm light. The Informer is set up with maximum and
minimum flow rate threshold values and the flow alarm
is enabled. The alarm light will turn on whenever the
maximum flow rate threshold is reached or exceeded,
or whenever the flow rate is less than or equal to the
minimum threshold value for more than three seconds.
If the flow rate drops to zero in less than three seconds
(e.g., gun shut off) the alarm light will stay off. Option-
ally, the Informer’s output can be wired to a PLC
instead of the alarm light, for integration into a control
system.
Example 2: Batch Dispense Control
The Informer is used as a batch dispense controller.
The desired batch volume is entered into the Inform-
er’s batch totalizer target value. Fluid flows through
the pipe until the selected volume is reached and the
flow valve is closed. The process repeats when the
batch reset button is pressed.
A power supply is used to power the Informer, the
batch complete light, the batch reset push button
signal, the batch alarm control relay, and the flow
valve. The Informer is set up by selecting the batch
totalizer units, target value, selecting the count-up with
manual reset function, and enabling the batch alarm
output. When the batch totalizer reaches the pro-
grammed target value, the batch alarm output turns
on, pulling in the control relay. The normally open
contact of the control relay illuminates the “batch
complete” light when the batch alarm is active. The
normally closed contact turns off the fluid valve when
the batch alarm is active.
