Please read before installing this equipment. Failure to do so may void your warranty.
Installation
The 801 ow meter gives the best accuracy when there is a smooth, unobstructed
ow through it. To minimize turbulance, there should be at least twelve inches of
straight plumbing upstream from the ow meter and at least 6 inches of straight
plumbing downstream from the ow meter. Mount the ow meter in a location that
physically protects it from damage and allows liquid to drain away after the sprayer is
ushed and secured at the end of the operating day. A straight, vertical section of the
main boom supply line is the ideal location for the ow meter.
Keep the ow meter from lying in a low section of the sprayer plumbing. This is
particularly important in cold weather when water might freeze in the ow meter and
cause damage to the unit. It is also important when applying chemical suspensions
which may settle out and stall the ow meter turbine if they cannot drain away.

Before installing the ow meter insert, make sure there are no obstructions in the
insert cavity. Clearance at the bottom of the cavity is very close and over tightening
or compressing of foreign material in the cavity can cause damage to the ow meter
body. Turn the insert in until it is hand tight.
Prior to each day’s spraying, the ow meter should be inspected to ensure there are
no leaks around the attachment ttings. At the end of the day, care should be taken
to thoroughly ush the ow meter with clean water.
Make sure no water or sediment is trapped in the flow meter
The impeller type ow meters supplied by TeeJet Technologies are inherently rugged.
However, continued use over time will eventually wear the internal bearings and
shafts until the meter becomes inaccurate. Replacement kits are available to repair
the ow meters. Contact your TeeJet Technologies dealer for these parts.
