TROUBLESHOOTING GUIDE
Trouble
Possible Cause
Remedy
Meter indicates higher than actual rate
Incorrect K factor entry
Correct K factor
Debris on rotor support
Clean meter
Buildup of foreign material on meter
bore
Clean meter
Meter indicates lower than actual flow rate
Incorrect K factor entry
Correct K factor
Wrong magnetic pickup
Use only B111113 pickup
Incorrect or missing pressure and/or
temperature entries
Correct pressure and/or
temperature entries
Debris on rotor
Clean meter and add filter
Worn bearing
Replace rotor and add filter
Erratic system indication, meter alone
works well (remote monitor
application only)
Ground loop in shielding
Ground shield one place only .
Look for internal electronic
instrument ground . Reroute
cables away from electrical noise .
Indicator shows flow when shut off
Mechanical vibration causes rotor to
oscillate without turning
Isolate meter
Erratic indication at low flow, good
indication at high flow
Rotor has foreign material wrapped
around it
Clean meter and add filter
No flow indication
Rotor not turning
Clean rotor or replace rotor
cartridge
Faulty pickup
Replace pickup
Broken wire in cable between flow
sensor and receiving electronics
Repair or replace cable
System works perfect, except indicates
lower flow over entire range
Bypass flow, leak
Repair or replace bypass valves,
or faulty solenoid valves
