Fluid flowing through the FPB1400
causes the paddlewheel to spin. As
the magnets embedded in the
paddle spin past the sensor,
electrical pulses are produced in
which frequency is proportional to
the flow rate. The number of pulses
per desired time interval and the
K-factor (number of pulses/gallon)
make it is easy to calculate the flow
rate and volume passing through
