About Sprayer Tank Dilution Calculator
This app is intended to help assist in maximizing the utility of a clean water supply for rinsing a sprayer tank and booms. It is based on three factors:
1. Tank Remainder - the amount of spray liquid remaining in the tank sump, the suction line to the pump, and the return line from the pump to the tank.
2. Rinse Volume - the amount of clean water introduced to the tank. This amount mixes with the Tank Remainder and is eventually pumped out the booms.
3. Number of Rinses - the number of times that clean water is introduced and mixed with the tank remainder.
Use the calculator to determine the impact of wash volume and the number of consequtive rinses on the dilution of the original spray mixture.
CalculationsThis calculator relies on an estimate of the tank remainder volume. If this amount is not specified in the sprayer's user manual, it can be estimated by measuring the length of suction hose and its diameter, the length of return line and its diameter, and the sump volume. For each rinse cycle, the operator enters the Tank Remainder and the Rinse Volume. The app calculates the relative amount of pesticide remaining after each rinse cycle. The degree of dilution will increase with the number of rinses and the Rinse Volume, and is strongly dependent on the Tank Remainder amount.
Other Considerations.The dilution of the tank remainder is an important step in cleaning a sprayer, but it is not the only part of the sprayer requiring attention. Ensure that rinse water contains ammonia or surfactant as directed by product labels. Examine all screens for pesticide residue. Allow for sufficient time for residue to become dissolved in the rinsate. Ensure that boom ends are flushed clean.
