What is the benefit of keeping the main carrier tank loaded with clean water in a direct metering system?

Keeping the main carrier tank loaded with clean water in a direct metering system is primarily about minimizing operator exposure to chemicals. When the tank contains only clean water, it reduces the likelihood of any chemical spills or leaks that could expose the operator to potentially harmful substances. This practice ensures that the operator can handle the equipment safely without direct contact with pesticides or other chemicals, thereby promoting a safer working environment.

In addition, having a clean water carrier helps facilitate the proper mixing and delivery of pesticides, ensuring that the chemicals are effectively metered without accidental exposure during the mixing process. This is crucial for maintaining safety standards and protecting the health of the operator while also ensuring effective application techniques.
