MAINTENANCE
Maintenance Equipment
With the exception of a special change gear mesh gage and a calibration test tank, the tools required are the usual
compliment of standard hand tools used by plumbers and mechanics

Preventive Maintenance
Periodic Inspection
1 Visually inspect the turbo meter and meter-mounted accessory Repair or replace components as required based on the
visual inspection
2 Verify that the meter operates at the proper flow rate and pressure A loss in pressure, coupled with the resulting decrease
in flow rate, may indicate the screen in the upstream pipeline is clogged with material and requires cleaning
Cleaning
1 Clean all dust, dirt, grease, moisture or other foreign material from the exterior of the meter and meter-
mounted accessory
2 If the piping arrangement of the facility includes a flushing system, shutoff the liquid flow to the meter Flush the interior
of the meter with an appropriate cleaning fluid to remove any buildup of deposits or corrosion on the internal portion of
the meter
Calibration Check and Adjustment
Accuracy of Badger turbo meters is tested at the factory with water However, due to possible use of liquids that could vary
in viscosity, it may be necessary to recalibrate a meter under operating conditions The following instructions are to assist in
performing a calibration adjustment
Accuracy Test
1 Place a test tank of known volume at output of meter
2 Operate the meter until the test tank is filled to a calibrated level Run at the actual flow rate used in the operation
3 Record the quantity indicated on the meter accessory
4 Perform the following calculations to determine percent of accuracy of the meter-accessory combination:
Qty Indicated on Accessory
X 100 = Meter Accuracy
Actual Quantity in Test Tank
Example 1:
95 Gallons
x 100 = 95% Accuracy
100 Gallons
In this example, the accessory is slow and must be speeded up by a change gear or electronic scaling correction
Example 2:
104 Gallons
X 100 = 104% Accuracy
100 Gallons
In this example, the accessory is fast and must be slowed down
