What unit of measurement is used by gas chlorinators to meter chlorine?

Gas chlorinators are designed to add chlorine to water systems in precise amounts to effectively control the disinfection process. The most suitable unit of measurement for this purpose is pounds per day. This measurement allows for the accurate monitoring of chlorine dosage over a specified period, which is essential for maintaining water quality in treatment facilities.

Using pounds per day provides operators with a clear metric that aligns with the volume of water being treated and the chlorine demand of that water. This unit also facilitates the planning and management of chlorine supply for larger systems where chlorine is fed continuously over time.

While other units such as gallons/hour or liters/minute may be used in different contexts, they do not accurately convey the total amount of chlorine being delivered over an extended time frame for disinfection purposes. Grams/hour, while still a valid measurement, is less practical for larger water treatment systems where dosage is typically expressed in larger containers, making pounds per day the most universally applicable and practical choice for gas chlorination applications.
