C.2. INSTALLING APPLICATION RATE SENSORS
C.2.1. FLOWMETER/PRESSURE SENSOR (FLOW SENSOR) 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 a few general mounting tips which should be considered for any flow sensor installation.
The accuracy of the flow sensor depends on a smooth, unobstructed flow through the device. Every effort should be
made to mount the flow sensor 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 flow sensor.
Additionally, if the flow sensor 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.
The flow sensor must provide the ARC control console with a continuous measurement of total liquid actually dis-
charged by the sprayer. To accomplish the required measurement, the flow sensor 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 Appendix B).

The flow sensor 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. Do not install the flow sensor in
a low section of tubing. This is particularly important in cold weather, when water could freeze in the flow sensor and
damage the internal mechanism. It is also important when applying chemical suspensions which may settle out and jam
the flow sensor 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 flow sensor to protect it from deform-
ing and vibration.
