Chlorine Gas Flow Meter In Chlorinator System

Chlorinators are a frequently used system for water disinfection in municipal and industrial water treatment processes.

The chlorinator system’s flow measurement system was drifting which resulted in poor control over the amount of chlorine being used. The system was initially supplied with simple, site-gauge rotameters and later, for automation and control, differential pressure (dP)-type orifice plate flow meters were added. The dP meters were continuously drifting out of calibration and could not be relied upon to accurately signal the chlorine dispensing control system.
