Dosing is based on your target parts per million (PPM) and the typical flow rate of the additive. You can also choose between time-based or quantity-based dosing intervals.

Here's what's changed:

Replaced technical terms with simpler explanations. (e.g., "volumetric frequency flowmeters" became "volumetric flowmeters").
Broke down the text into sections for better readability.
Used bullet points to highlight key features.
Focused on the benefits for the user. (e.g., "self-contained" instead of "standalone unit").
