The Precision Flow Meters can be installed anywhere between the distribution manifold
and the check valve/orifice assembly. Primary consideration should be given to ease of
access to the flow meters. Because a flow meter is installed for each row it is a good
idea to mount the meters in a “grouping” close to the output of the manifold. A
bracket (P/N AE6675) is available to hold 8 flow meters in a 9” space. All the fertilizer
lines can be run in a neat and orderly manner from the manifold to the flow meter and
from the flow meter to the row. This will also make the wiring harness less complex, as
the length of wire required to hook the flow meters up will be reduced and all the
connections will be in one location.
It is also recommend that once you have commenced planting and the lines and the
flow meters have been filled with fertilizer that they remain fully charged until finished
planting for the season. This will help insure that crusting/plugging does not occur and
that the flow meter turbine will remain free once planting begins again. This is the
reason we want the check valves installed in the system as this will insure the lines stay
fully charged once the pumping stops. If – for example planting is delayed due to rain
the check valves will insure that the lines remain fully charged and you will not be
required to flush out the system. PLEASE NOTE: One exception to this rule is if you have
micro nutrients mixed in with your fertilizer and the planter is going to be setting for more
than a couple of days flushing of the system is recommended as the ingredients may
settle and may cause problems once planting starts again. Once again if you have
made plans for flushing of the system and planting is delayed we would recommend,
you go ahead and flush the system to insure no problems will occur on startup.
