Airblast coverage depends on moving spray-laden air into and through the target canopy. A headline reach distance cannot describe coverage by itself. Canopy height, depth, density, row geometry, fan airflow, nozzle distribution, droplet spectrum, travel speed, weather and calibration all affect deposition.
MERI RCS airblast reach listed by model
The current RCS Series TDS lists seven airblast reach figures: ME-RCS100 (100 L), up to 7 m; ME-RCS120 (120 L), up to 12 m wide / 5.5 m high; ME-RCS200 (200 L), up to 14 m wide / 6 m high; ME-RCS300 (300 L), up to 16 m wide / 8 m high; ME-RCS400 (400 L), up to 16 m wide / 8 m high; ME-RCS500 (500 L), up to 16 m wide / 10 m high; and ME-RCS800 (800 L), up to 13 m. These are TDS-listed maximum reach figures, not a guarantee of uniform spray deposition across every canopy.
| Model | Tank | TDS-listed airblast reach |
|---|---|---|
| ME-RCS100 | 100 L | Up to 7 m |
| ME-RCS120 | 120 L | Up to 12 m wide / 5.5 m high |
| ME-RCS200 | 200 L | Up to 14 m wide / 6 m high |
| ME-RCS300 | 300 L | Up to 16 m wide / 8 m high |
| ME-RCS400 | 400 L | Up to 16 m wide / 8 m high |
| ME-RCS500 | 500 L | Up to 16 m wide / 10 m high |
| ME-RCS800 | 800 L | Up to 13 m |
Configuration note: The TDS marks these values as dependent on engine, pump, nozzle, fan and order configuration. The ME-RCS120 through ME-RCS500 figures distinguish width and height; the ME-RCS100 and ME-RCS800 figures are listed as a single reach value. Match the airblast setup to the measured canopy, then verify deposition in representative lower, middle and upper zones.
Direct recommendation
Measure the representative canopy and configure airflow to displace or penetrate it without simply carrying spray beyond the target. Align active nozzles with the canopy, choose output from the approved rate and verify distribution with an accepted field method. Treat visual mist reach as an observation, not proof of coverage.
Decision framework
| Decision | System A / fact | System B / boundary |
|---|---|---|
| Canopy geometry | Height, depth, density, gaps and row spacing | Defines required air and nozzle zones |
| Air system | Fan output, outlet direction and travel speed | Must fit canopy rather than maximize airflow |
| Liquid system | Nozzles, pressure, flow and distribution | Based on approved application and calibration |
| Weather | Wind, temperature and humidity within local rules | Can change drift and deposition |
| Evidence | Coverage cards or approved assessment method | Record setup and representative conditions |
Profile the canopy by height
Measure lower, middle and upper target zones plus canopy depth. Record gaps and asymmetric growth. A single maximum tree height does not tell the operator where output is needed.
Match air, do not maximize it
Extension guidance emphasizes sufficient air volume and velocity for transport and penetration, while excessive air can move droplets through or beyond the canopy. Adjust the complete system to the crop and verify it.
Align nozzles with active foliage
Deactivate or redirect positions that do not target the canopy when the approved equipment and process allow. Set the liquid distribution by zone so upper and inner targets receive the planned share without spraying empty space.
Control travel speed
Speed affects time for air and droplets to interact with the canopy. Use the calibrated operating method and record it. Published carrier travel capability is not an application speed recommendation.
Evaluate drift conditions
Follow label, weather limits, buffer requirements and local rules. Stop when wind or other conditions move outside the approved plan. Remote operation does not remove environmental responsibility.
Verify coverage with evidence
Use an accepted method such as water-sensitive cards or the locally approved alternative, positioned through representative canopy zones. Record fan, nozzles, pressure, speed, weather and crop state with the result.
Evidence to collect
- Exact model, working system, options and current documents.
- Representative task, site measurements, media and required result.
- Operating method, environmental conditions and stop criteria.
- Dated quotation for configuration-specific commercial facts.
