What is a direct metering system in a spray application?

A direct metering system in a spray application is specifically designed to combine herbicides with diluent water at the suction side of the pump. This setup allows for real-time mixing of the herbicide as it is being drawn into the spray system, ensuring that the right concentration is achieved just before application. This method enhances precision because it can adjust to varying application rates and ensures the herbicide is well mixed with the diluent immediately before being sprayed.

By mixing at the suction side, there is less risk of separation or instability of the mixture, which can sometimes occur with pre-mixed solutions. This method is particularly beneficial for maintaining the efficacy of the herbicide, as it ensures that the product is used fresh right at the point of application, allowing for better control over the amount used and reducing waste. The direct nature of this system makes it a preferred choice in many professional aquatic pest control situations.

In contrast to other options, this method clearly demonstrates a sophisticated approach to pest control that promotes accuracy and reliability in application.
