Cleaning and Inspection
Note: If the inner cartridge is damaged or contaminated beyond repair, the complete
meter can be sent to the manufacturer for evaluation. The manufacturer will
inspect, repair, and/or replace parts as needed according to the warranty.
1. Inspect inner cartridge and body casing for contamination.
If the inner cartridge did not slide out freely, it may be a sign of
contamination. Locate and eliminate the source of contamination
before reconnecting meter to the system or the same problem
will reoccur. It may be necessary to install finer filtration or a
magnetic filter in the system.
2. Soak inner cartridge assembly (or individual parts, depending on
level of disassembly) in a suitable cleaning solvent. Naptha or
Stoddard is recommended.
CAUTION: When using an air hose wear proper eye protection.
3. Remove parts from solvent. Use an air hose and/or scrub with a
light brush to remove any remaining contaminants. Remove any
magnetized particles from transfer magnet.
4. Inspect inner cartridge for scored or worn parts. Replace parts as
needed. (Parts are available from your local distributor.)
5. Remove any contaminants from inside body casing.
6. Clean Lexan widow tube with soap and water, or a compatible
cleaning solvent. IMPORTANT: Some solvents may cause
damage to Lexan tube, check compatibility of solvent being used.
7. Clean and inspect seal assemblies (O-rings and seals) for nicks
or cuts. Replace as needed.
8. Clean and inspect the meter every six months.
Properly filtered meters will provide years of trouble-free service. If
the meter is not properly filtered, it may be damaged and malfunction.
Meter damage caused by excessive contamination in not covered
under warranty.
