Differential Pressure Flowmeter
If a differential pressure flowmeter that does not output flow directly is used, the analog inputs must be
configured as QUADRATIC and the K value of the flowmeter and specific gravity of the fluid entered.
Either Analog Input 1 [AI1] or Analog Input 2 [AI2] could be used. AI1 is used if a flow signal is being used for the
variable setpoint or offset features [See
Setpoints
]. AI2 is used if the operating mode is FLOW CONTROL and a dP
flowmeter is being used as the process control instrument [this is the most common configuration].
NOTE: Both AI1 and AI2 can be configured for a differential pressure type flowmeter [quadratic] however the K
value and specific gravity of the two meters must be identical.
Parameter Name Value/Range Note(s)
17.01 AI1 SENSOR LINEAR
[default]
QUADRATIC
Change to Quadratic for dP flowmeter.
17.02 AI2 SENSOR LINEAR [default]
QUADRATIC
Change to Quadratic for dP flowmeter.
17.03 K-DP FLOWMETER 0-1000 K values may be provided by the
flowmeter manufacturer. To calculate
the “K” value, refer to the equations
provided below

M Depending upon where the dP
flowmeter is being used, the units of
parameter(s) 15.01 and 15.02 need to
be changed. Note parameter 11.03,
Mode Select, must be set to pressure.
If the dP flowmeter is being used as
the primary process flowmeter [AI2],
then 15.01 must be in units of
pressure.
If the dP flowmeter is being used for
variable setpoints [AI1], then 15.02
must be changed to units of pressure.
If both AI1 and AI2 are using a dP
flowmeter [again…they must be
identical and on identical services],
then both 15.01 and 15.02 must be in
units of pressure.
PumpSmart will display the actual
signal in terms of flow; If PSIG or FT are
used, flow will be read as GPM. If BAR
or Meters are used, flow will be
displayed as M3HR.
