The fiber transmitter and receiver are designed to
be a rugged and reliable system. Periodic
preventative maintenance is not required.

AND TRANSMITTER AND TRANSMITTER AND TRANSMITTER AND TRANSMITTER AND TRANSMITTER
In some applications the RF 1 meter is used in an
application where the exterior of the meter and
transmitter must be periodically cleaned. An
example of such an application would be serving
as a paint meter in a paint booth system.

regular copper wire! The fiber cable can
be damaged if it is bent too sharply. Please
observe the minimum bend radius speci-
fication during installation.

The meter itself is made out of stainless steel and
is impervious to water based solvents so that no
precautions are necessary with the meter. The
transmitter and it’s components are enclosed in a
nylon enclosure which is highly resistant to water
based solvents. As a precaution avoid the
possibility of forcing the cleaning solution into the
fiber cable connector or the small gap between the
transmitter and the meter.

The meter itself is made out of stainless steel and
is impervious to chemical based solvents so that
no precautions are necessary with the meter. The
transmitter and its components are enclosed in a
nylon enclosure that is resistant to chemical sol-
vents such as MEK. When using solvents such
as MEK use as little as possible and keep the
contact time with the transmitter as short as
possible. Avoid the possibility of forcing the
cleaning solvent into the fiber cable connector or
the small gap between the transmitter and the
meter.

Air purges are often used in automatic coating
operations for rapid color changes and to minimize
the amount of solvent required to flush-out the old
color. Special considerations must be made
when using air purges through the flow meter.
1. Air purges do not provide the lubrication the
flow meter gears require. Lubrication is normally
provided by the metered fluid or solvent.
2. Air purges can cause some coating materials
to “dry” on the flow meter shafts and gears thus
affecting the performance characteristics of the
flowmeter, especially when water-based materials
are used.
3. Excessively long air purges will cause prema-
ture gear and shaft failure.
