TROUBLESHOOTING

Problem
No signal after installation
Inaccurate metering
Seametrics • 253.872.0284
Probable Cause
Insufficient flow
Bad connections to control
electronics
Incompatible control
Damaged or missing rotor
Failed magnetic sensor
Not enough straight pipe
between meter and severe flow
disturbance
Wrong K-Factory entered
Magnetic sensor failing to pick up
each blade
Wrong time units on flow
indicator

Things to Try...

Consult Flow Rate Chart
Reduce pipe size or use different sensor
Check connections at control:
Red (+), Black (-), White (signal)
Use 6-36 Vdc power supply - for low power
Use 3.1-16 Vdc power supply - for micropowered
Add pull up resistor, if using current-sourcing
device
Remove flow sensor from fitting and check for free
spinning; replace rotor
See Signal Troubleshooting (page 11); replace
magnetic sensor
Move meter away from flow disturbance or field
calibrate
Check fitting for K-Factor, check indicator to see
if it is entered properly ("Set K" on FT430, FT440,
FT450, or FT520)
Remove flow sensor from pipe. If indicator is
FT430, FT440, FT450, or FT520, set K to 1.00, turn
rotor slowly by hand, indicator should cound each
blade; replace sensor
If using FT430, FT440, or FT520, check left side of
display (sec, min, hr, day); change to desired unit
