TeeJet TECHNOLOGIES 801-802 Flow Meters
Installation
- The 801 and 802 flow meters give the best accuracy when there is a smooth, unobstructed flow through them.
- To minimize turbulence, there should be at least 12″/30cm of straight plumbing upstream from the flow meter and at least 6″/15cm of straight plumbing downstream from the flow meter.
- A straight, vertical section of the main boom supply line is the ideal location for the flow meter.
- This is particularly important in cold weather when water might freeze in the flow meter and cause damage to the unit.
- It is also important when applying chemical suspensions, which may settle out and stall the flow meter turbine if they cannot drain away.
How To Install
Before installing the flow meter insert, make sure there are no obstructions in the insert cavity. Clearance at the bottom of the cavity is very close, and over-compressing of foreign material in the cavity can cause damage to the flow meter body. For 801, turn the insert locking collar until it is hand-tight.
Before each day’s spraying, the flow meter should be inspected to ensure there are no leaks around the attachment fittings. 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 flow meters. Contact your TeeJet Technologies dealer for these parts.
