Accurate Gas Flow Measurement Improves Water Disinfection Process Efficiency By Tristan J. Williams, Sr. Member Technical Staff Fluid Components International hazard to plant employees if improperly handled or if there are leaks in tanks, lines or valves. This gas is also corrosive and reacts with instrument-wetted materials over time, potentially causing oxidation and failure. When too little chlorine is added to the water, disease problems can result that affect people’s health. When too much chlorine is added, the quality of taste can resemble a “swimming pool” flavor. To ensure the right...

Accurate Gas Flow Measurement Improves Water Disinfection Process Efficiency By Tristan J. Williams, Sr. Member Technical Staff Fluid Components International sensing is one of only a few technologies that measure mass flow rate; it is also one of the few technologies that can be used for measuring gas mass flow in large pipes, ducts, or stacks. Measurement of the fluid temperature is also provided by thermal technology. A thermal mass flow sensing element contains two thermowell-protected platinum resistance temperature detectors. When placed in the process gas stream, one resistance temperature...
