Vol. per Stroke
Type in the text box the volume of chemical that the metering pump delivers each time it strokes
the diaphragm. This information is used to totalize the volume of chemical delivered, by
multiplying the volume per stroke by the number of strokes counted by the Feed Verification
device.
Alarm Time
Type in the text box the amount of time that can pass between the output relay being activated and
the Feed Verification device sensing a stroke of the pump. If the pump is set to deliver 10 strokes
per minute, then the controller must wait a minimum of 6 seconds before activating the alarm.
Total
This column tells you the volume of chemical that has been delivered by the metering pump. This
value is calculated by multiplying the volume per stroke by the number of strokes counted by the
Feed Verification device.
Last Reset Time
This column gives you the date and time that the total was last reset.
Reset Total
