| Operation |
As
flow is established through the unit a magnetic piston
is displaced proportional to the volumetric flow rate.
A transducer senses the displacement of the piston
as flow increases and decreases. A conditioning circuit
converts the transducer signal to either an analog
or digital output.

Actuation
points for air at 68° F and 14.7 PSIA with increasing
flow. |
| |
Deactuation
(decreasing flow) averages 10% less than actuation
(increasing flow). |

Temperature
Operating Range:
AMBIENT: 32° to 160° F (0° to 71° C)
MEDIA: 32° to 180° F (0° to 82° C) |
Performance:
N.O.: Conduit Offset Down
N.C.: Conduit Offset Up |
Installation:
(For
detailed information see Installation and Maintenance
Sheet.) 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. A 10 micron filter is recommended. |
