24. A method for determining a concentration of a chemical in a fluid obtained from a process stream comprising:
placing a flow cell in fluid communication within a flow of fluid from a process stream, such that there is a generally continuous flow of fluid through the flow cell, wherein the flow cell comprises:
a first body section and a second body section, and a gasket arranged to seal between the first body section and the second body section;
wherein the gasket, the first body section, and the second body section together define one or more chambers, each chamber having a perimeter with a narrower end and a rounded wider end;
each chamber having an inlet passage in fluid communication with the chamber, an outlet passage in fluid communication with the chamber, and a biosensor arranged in fluid communication with the chamber;
wherein each inlet passage directs fluid into the respective chamber proximal the narrower end of the chamber at an angle of between about 45° to about 75° relative to a plane of the gasket and each outlet passage directs fluid flow out of the wider end of the chamber at an angle between about 45° to about 75° relative to the plane of the gasket, the inlet passage and outlet passage being angled in opposite directions; and
the flow cell further comprising an electronic measurement system in electrical communication with each of the one or more biosensors and configured to transmit data to a data processor; and
transmitting measurement data from the electronic measurement system to a processor.
