DO:
Install bypass plumbing around the ow meter. This is
useful during start up for removing dirt and air from
the plumbing or when measuring uid that may freeze
inside the line and need to be remelted before it can
pass through the meter. It also allows removing the
ow
meter for service without disabling the system.
DO:
Be very careful to keep parts clean during installation
or teardown. A little dirt can look like a truckload
compared to the 10 micron ltration requirement for
series 210 Meters.
DO:
Clean the lter on a regular basis.
DON’T:
Run water or aqueous solutions not approved by Max
through your ow 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 ow 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 ow meter. These are precision
devices which require special tools and techniques.
DON’T:
Turn on the pump in a system lled with material that
is solid at room temperature. Wait until the material
is completely melted and use the ow meter bypass
valve during start up.
DON’T:
Apply excessive differential pressure across the ow
meter as it will cause internal failure (see the pressure
drop curves for safe area operation).
DON’T:
Over pressurize the meter. Maximum pressure is either
1,000 PSI (70 bar) 3,000 PSI (210 bar) or 7250 PSI
(500 bar) depending on model purchased.
DON’T:
Exceed the maximum ow rates for the material
viscosity.
DON’T:
Allow materials which solidify in air to set up in the
ow 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.
