the operator that the pressure or flow is higher than it should be on a given line and allow them to adjust the pump set-
tings to lower the pressure or flow accordingly . See Section 7 .3, ALARM LIMITS for details regarding setup .

Used" . This will display until the buttons are released . The units will be displayed in the same units as the flow . If the flow
is set to display in GPM, the totalizer will display GALLONS . If the flow is set to display in LPM, the totalizer will display
LITERS .
