What does the rotometer on a gas chlorinator measure?

Gallons per hour
Pounds per day
Pounds per 24 hours
Liters per minute

The correct answer is: Pounds per 24 hours

The rotometer on a gas chlorinator measures the flow of gas, typically chlorine, in a way that indicates the amount being delivered for disinfection purposes. It is crucial for maintaining the appropriate concentration of chlorine in water treatment processes. The correct choice indicates that the rotometer is used to measure the flow rate in pounds of chlorine per 24 hours. This is important in water treatment facilities where precise dosing of chlorine is required to ensure safe drinking water. Knowing the flow in pounds per day facilitates calculation for daily treatment needs, taking into account variations in water supply and quality. Accurate dosing is vital in preventing under or overdosing, which could lead to ineffective disinfection or harmful effects on public health. The incorrect options, such as gallons per hour, pounds per day, or liters per minute, either do not reflect the typical units used or fail to capture the necessary duration for the flow measurement essential in ensuring effective chlorination in water treatment processes.
