DO:
Install bypass plumbing around the flow meter. This is
useful during start up for removing dirt and air from
the plumbing or when measuring fluid that may freeze
inside the line and need to be remelted before it can
pass through the meter. It also allows removing the
flow
meter for service without disabling the system.
DO:
Install the meter on its side.
DO:
Be very careful to keep parts clean during installation
or teardown. A little dirt can look like a truckload
compared to the 10 to 30 micron filtration requirement
for G-Series Meters.
DO:
Clean the filter on a regular basis.
DON’T:
Run water or aqueous solutions not approved by Max
through your flow meter because of internal galling.
DON’T:
Steam clean the meter (bypass or remove the meter if
necessary).
DON’T:
Blow down the meter with compressed air or gas
because it may over-speed and damage the meter.
DON’T:
Remove the Transmitter from the flow meter body.
The transmitter is phased to the meter and a
measurement error will result. Re-calibration will be
necessary; see the transmitter interface software
manual.
DON’T:
Disassemble the flow meter. These are precision
devices which require special tools and techniques.
DON’T:
Turn on the pump in a system filled with material that
is solid at room temperature. Wait until the material
is completely melted and use the flow meter bypass
valve during start up.
DON’T:
Apply excessive differential pressure across the flow
meter as it will cause internal failure (see the pressure
drop curves for safe area operation).
DON’T:
Over pressurize the meter. Consult specification table
for maximum pressure.
DON’T:
Exceed the maximum flow rates for the material
viscosity.
DON’T:
Allow materials which solidify in air to set up in the
flow meter. These may be impossible to remove. If
the meter needs to be removed for repair and cannot
be completely cleaned. Plug the inlet and outlet ports
at once.
