Product Information
801/802 Flow Meters
The 801/802 Flow Meters are impeller type flow meters that are designed to
measure the flow rate of liquids in sprayer plumbing. The flow meters are made
with durable materials such as glass-filled polypropylene, stainless steel,
and sapphire, which makes them inherently rugged and long-lasting. The flow
meters have LED indicators that show the power and signal status.

Installation Instructions
- Keep the flow meter from lying in a low section of the sprayer plumbing. 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.
- 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. For 802, install the flow meter insert until the pin openings are aligned.
- Prior to each day’s spraying, the flow meter should be inspected to ensure there are no leaks around the attachment fittings.
- At the end of the day, care should be taken to thoroughly flush the flow meter with clean water.
- Make sure no water or sediment is trapped in the flow meter.
- The Flow Meter must be mounted so that it will drain completely when the sprayer is not operating.
Note: The impeller type flow 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 flow meters. Contact your TeeJet Technologies dealer for these parts.
The 801 and 802 flow meters give the best accuracy when there is a smooth, unobstructed flow through it. 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. Mount the flow meter in a location that physically protects it from damage and allows liquid to drain away after the sprayer is flushed 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 flow meter.
