Why must make-up or dilution water for a saturator be metered?

Make-up or dilution water for a saturator must be metered primarily to maintain solution strength. This is essential because the concentration of the solution needs to remain consistent for the process to function properly. If the volume of make-up water added is uncontrolled, it could lead to either an overly diluted solution, affecting the efficacy of the saturator, or too strong a solution, which could cause operational problems and inefficiency in the system.

Metering allows precise control of the amount of water entering the system, ensuring that the desired concentration and chemistry are upheld. This is crucial for processes that rely on consistent chemical properties, such as water treatment or other industrial applications, where the ratio of water to chemicals significantly impacts performance and outcomes.
