Clean meter.
Clean meter.
Install gas eliminator ahead of meter.
Meter indicates lower than actual
flow rate.
Debris on rotor.

Clean meter and add filter.
Clean meter and add filter.
Recalibrate monitor.
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.
No flow indication.
Full or partial open position.
Fluid shock, full flow into dry meter or
impact caused bearing separation or
broken rotor shaft.
Rebuild meter with repair kit and recali-
brate monitor. Move to location where
meter is full on startup or add down-
stream flow control valve.
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. Faulty pickup. Replace pickup.
System works perfect, except indicates
lower flow over entire range.
By-pass flow, leak. Repair or replace bypass valves, or
faulty solenoid valves.
Meter indicating high flow, upstream
piping at meter smaller than
meter bore.
Fluid jet impingement on rotor. Change piping.
Meter indicating low flow, upstream
piping at meter smaller than meter
bore.
Viscosity lower than calibrated. Change temperature, change fluid or
recalibrate meter.
