Unlike Clark type cells with a membrane, the Insite DO sensors do not require any flow. Clark type DO sensors actually consume oxygen to make the measurement so a new supply of oxygen must be continuously provided. The Insite sensor does not consume anything so no flow is needed to obtain a correct reading.
