Do’s and Don’ts

DO:

Install bypass plumbing around the flow meter . This is useful during start-up for removing dirt

and

air from the plumbing or when metering high temperature materials . It also allows removing the

flow meter for service without disabling the system .

DO:

Be very careful to keep parts clean during installation or a teardown . A little dirt can look like a

truckload compared to the 10 micron filtration requirement .

DO:

Clean the filter on a regular basis .

DO:

Use the flow meter with liquids that will not harm the mechanism .

Contact Max Technical Service if in doubt .

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 overspeed and damage the

meter .

DON’T:

Disassemble the flow meter . These are precision devices which require special tools and techniques .

DON’T:

Apply excessive differential pressure across the meter or exceed the maximum pressure

specification .

DON’T:

Exceed the maximum flow rates for the material viscosity .

DON’T:

Exceed the maximum fluid or transmitter housing temperatures .

DON’T:

Allow materials which solidify in air to set-up in the flow meter . These may be impossible to remove .

the meter needs to be removed for repair and cannot be completely cleaned, plug the inlet and

outlet

ports at once .

DON’T:

Turn on the pump in a system filled with solidified material . Wait until the material is completely

melted

and use the flow meter bypass valve during start-up .
