In general, pilot system should have provision for measuring the ozone concentration and the gas flow rate. The system should also have the provisions for measuring the reactor ozone concentration in the off gas to be able to determine the transferred ozone doze. To simplify ozone measurements, gas manifold system can be constructed to split generator output flow into several streams, each with its own flowmeter. The feed and off gas will be monitored with ozone gas monitor. Pilot plants could use commercially available gas phase ozone monitors that use UV absorption of ozone to measure the concentration in the gas stream. UV analysers are applied for ozone concentrations range 0-200 ppm. The ozone residual measurements use spectrophotometry with indigo method or some other colorimetric technique. Indigo method is based on the decolorization of an aqueous indigotrisulfonate reagent by ozone observed at 600 nm.
