Seametrics IP800-Series - Manual (Page 11)

Problem Probable Cause Try...
No signal
after installation
Inaccurate
metering
Consult Flow Range Chart
Reduce pipe size or use different
sensor
Check connections at control;
Red (+), Black (-), White (signal)
Use 6-24 Vdc power supply
Add pull up resistor, if using current-
sourcing device
Remove flow sensor from fitting and check
for free spinning; replace rotor
See signal troubleshooting; 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
FT420, FT415, FT520)
Remove flow sensor from pipe. If indicator
is FT415, FT420, FT520, set K to 1.00,
turn rotor slowly by hand, indicator should
count each blade; replace sensor
If using FT415 or FT420, check left side of
display (sec, min, hr, day); change to
desired unit
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-Factor entered
Magnetic sensor failing to pick up each blade
Wrong time units on flow indicator
