Maintenance
WARNING
Test equipment should be grounded to prevent a possible spark. Test area should have no ignition source. Operators should
wear personal protection and prevent any product exposure and environmental issues.
10). When removing gaskets or o-rings, carefully check for damage or corrosion. Any cracked, rough, worn, elon-
gated or swollen o-rings need to be replaced. When replacing the o-rings, place grease along the inside of the o
-ring groove or completely around the o-ring to help the o-ring stay in the
o-ring groove during assembly. If o-ring is pinched or not in the o-ring groove, the meter system will leak and
cause serious problems to the environment and equipment. Collect all replaced parts and dispose of properly.
Do not weld any part of the meter system or accessories as this will weaken the part and allow for leaks
11). All bolts and screws need to be coated with anti-seize. Then follow the torque specifications for each flow
meter.
12). Recommended levels of maintenance and inspection will depend upon the system variables, such as the prod-
ucts being measured, their corrosiveness, system pressure requirements, government or company regulations,
and age of metering system. If hydrostatic testing is required, the system pressure should not exceed 1.5 times
the marked meter pressure. It is not recommended to pneumatically test the meter system at anytime.
13). If any component of the meter system is removed from the system, it should be thoroughly flushed with a
compatible liquid. After this is done, immediately refill the meter or accessory with a compatible liquid to
prevent corrosion and water build up.
Storage Instructions
Short periods of non-use of the meter (a week or less) should present no problem, provided that the meter remains
full of product. For long periods of non-use, such as winter storage, the following procedure is recommended.
Before long-term storage, a good practice is calibration of the meter to determine that it is functioning properly.
1). To store the meter when it is left in line, flush the system with clean water until 70-80 gallons of
water have gone through the meter.
2) Pump a 50% anti-freeze / 50% water solution through the entire system (100% RV antifreeze may be used
instead). With the pump running, shut off a valve downstream from the meter, making sure that anti-freeze
solution is present at that point. Then close an upstream valve, such that the meter remains full of anti-freeze
solution.
3) Remove the register from the meter, and lubricate the drive coupling shaft. After lubrication, reassemble the
register onto the meter.
When starting the system after a period of storage, check the meter's calibration as detailed earlier in the service
manual.
