4-1 General
No routine maintenance, cleaning or lubrication is required on the
flowmeter. The user should establish a schedule for the periodic checking
and cleaning of the strainer. Cleaning the strainer depends upon product
application and time of use.
4-2 Manufacturer’s Maintenance Recommendations
The following items apply to all flowmeters. Users must give careful
consideration to the consequences that may be the result of failure to
follow manufacturer’s recommendations.
1. No attempt should be made by the user to alter any physical
dimension of the flowmeter or component part.
2. Do not use force to assemble or disassemble any component of
the flowmeter. All components are machined to exact tolerances.
3. When an unserviceable flowmeter has been returned to the
factory for rework, it must be understood that in extreme cases it
may be economically impractical to repair the flowmeter.
4. Rotors are manufactured as a subassembly and are available as
replacement parts, or spare parts.
