HIGH ALARM (Labeled RELAY-1 on the Main PCB)
Controls the set-point of the SPDT relay labeled RELAY-1
on the Main PCB. Enter a liquid velocity
at which a relay-
contact action is desired. Relay contacts are utilized for
signaling flow rate conditions that are higher of lower than
a desired set point. If a relay setting is made very close to
a nominal liquid velocity, relay “chatter” ( rapid opening
and closing of the relay ) may result.
n If a UNITS code for U.S. measurements was made the
HIGH ALARM value will be entered in FPS. Valid
ranges for this entry are 0.00 to 30.00 FPS.
n If a UNITS code for metric measurements was made
the HIGH ALARM value will be entered in MPS. Valid
ranges for this entry are 0.00 to 10.00 MPS.
LOW ALARM (Labeled RELAY-2 on the Main PCB)
Controls the set-point of the SPDT relay labeled RELAY-2
on the Main PCB. Enter a liquid velocity at which a relay-
contact action is desired. Relay contacts are utilized for
signaling flow rate conditions that are higher of lower than
a desired set point. If a relay setting is made very close to
a nominal liquid velocity, relay “chatter” ( rapid opening
and closing of the relay ) may result.

HIGH ALARM value will be entered in FPS. Valid

n If a UNITS code for metric measurements was made
the HIGH ALARM value will be entered in MPS. Valid
ranges for this entry are 0.00 to 10.00 MPS.
TOTAL MULT
Utilized for setting the flow totalizer exponent and
changing the External Counter output. This feature is
useful for accommodating a very large accumulated flow.
The exponent is a “ X 10
n
” multiplier, were “n” can be from
0 (10
0
, X 1 multiplier) to 4 (10
4
, X 10,000 multiplier).
