Fluid Ports:
MAO-500: 1/2" FNPT
Mounting:
Mount with INLET vertical, INLET port down, OUTLET port horizontal.
Temperature Operating Range:
AMBIENT: 0° to 125° F (-18° to 52° C)
MEDIA: 0° to 180° F (-18° to 82° C)
Installation:Control valves should be placed downstream of the MAO flow meter. The flow meter
should never be installed so that it drains completely when flow ceases.
When particles maybe present in the media, a filter should be installed ahead of the
flow meter. It is advisable to filter to 10 microns.
The MAO flow meter should not be located near ferrous material or near strong
electro-magnetic fields.
The MAO flow meter is sensitive to velocity profile disturbances in the flow stream.
It is advisable that straight lengths of 10 inside diameters upstream and 5 inside
diameters downstream be used.
All lines should be completely purged of air before use.
The use of pipe dope is not recommended. Use care when using Teflon tape to avoid
shreds from entering the MAO flow meter.
