Badger Meter QuikSert - Manual (Page 10)

OPERATIONAL STARTUP
The following steps should be followed when installing and starting the meter .
MAKE SURE THAT FLUID FLOW HAS BEEN SHUT OFF AND PRESSURE IN THE LINE RELEASED BEFORE ATTEMPTING TO
INSTALL THE METER IN AN EXISTING SYSTEM.
1 . After meter installation, close the isolation valves and open the bypass valve . Flow liquid through the bypass valve for
sufficient time to eliminate any air or gas in the flow line .
HIGH VELOCITY AIR OR GAS MAY DAMAGE THE INTERNAL COMPONENTS OF THE METER.
2 . Open upstream isolating valve slowly to eliminate hydraulic shock while charging the meter with the liquid . Open the
valve to full open .
3 . Open downstream isolating valve to permit meter to operate .
4 . Close the bypass valve to a full closed position .
5 . Adjust the downstream valve to provide the required flow rate through the meter .
OTEE: N The downstream valve may be used as a control valve .
TROUBLESHOOTING GUIDE
Trouble Possible Cause Remedy
Meter indicates higher than actual
flow rate
• Cavitation
• Debris on rotor support
• Build up of foreign material on meter
bore
• Gas in liquid
• Increase back pressure
• Clean meter
• Clean meter
• Install gas eliminator ahead of meter
Meter indicates lower than actual
flow rate
• Debris on rotor
• Worn bearing
• Viscosity higher than calibrated
• 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 recalibrate monitor .
Move to location where meter is full on startup or add
downstream 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
Bypass 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
Opposite effects of above Viscosity lower than calibrated Change temperature, change fluid or recalibrate meter
