4. Selecting a Location

• The FMG-3000 requires a full pipe and a fully developed turbulent fl ow profi le for accurate measurement.

• If the piping system harbors air pockets or bubbles, take steps to locate the sensor so the air pockets will not contact the
electrodes.

• In vertical installations, assemble the unit so the conduit ports are facing downward. This prevents condensation inside the conduit
from being directed into the electronics housing.

Select a location with suffi cient
distance of straight pipe immediately
upstream of the sensor.

2 x 90° Elbow

Locating the sensor in a trap or where the
fl ow is upward helps to protect the sensor
from exposure to air bubbles when the
system is in operation.
NOTE: The system must be designed to
keep the sensor wet at all times.

These confi gurations are not
recommended because it is diffi cult to
keep the pipe full.

In a gravity-fl ow system, the tank must be designed
so the level does not drop below the outlet.

This causes the pipe to draw air in from the tank.
If air bubbles pass across the Magmeter electrodes,
the output will become erratic.
