C.2. FLOWMETER INSTALLATION
The installer should refer to the detailed instructions shipped with the particular device being installed. MIDWEST
TECHNOLOGIES recommends that these specific installation instructions be attached to this manual for future refer-
ence. There are, however, a few general mounting tips which should be considered for any flowmeter installation.
The accuracy of the flowmeter depends on a smooth, unobstructed flow through the device. Every effort should be made
to mount the flowmeter in a straight section of the main boom supply line with at least twelve inches of straight flow
upstream from the device and at least six inches of straight flow downstream from the device. Sharp bends in the flow
stream caused by valves, kinks, elbows, tees, etc., can seriously degrade the performance of the flowmeter. Addition-
ally, if the flowmeter being installed is sensitive to the direction of flow, it will be marked with an arrow. These devices
should always be installed with the arrow pointing in the direction of normal flow.

PUMP DISCHARGE
The flowmeter must provide the TASC Control Console with a continuous measurement of total liquid actually dis-
charged by the sprayer. This includes both the main carrier and the injected chemical, after the two are mixed. To
accomplish the required measurement, the flowmeter must be installed in the main boom supply line, upstream from the
individual boom shut off valves and downstream from the flow control valve and pump bypass line, if used (See figure
above).
The flowmeter should be installed in a location that will physically protect it from damage and allow liquid to drain
away when the sprayer has been flushed and secured at the end of an operating day. Keep the flowmeter from lying in
a low section of tubing. This is particularly important in cold weather, when water could freeze in the flowmeter and
damage the internal mechanism. It is also important when applying chemical suspensions which may settle and obstruct
the flowmeter if they don't drain away. A straight, vertical section of the main boom supply line, is the ideal location for
the flowmeter. Firmly support the main boom supply line in the vicinity of the flowmeter to protect it from deforming
and vibration.
NOTE: THE FLOW METER MUST
BE MOUNTED SO THAT IT WILL
DRAIN COMPLETELY WHEN THE
SPRAYER IS NOT OPERATING!
