The emission of pollutants such as CO, CO2, NO, NO2, total NOx, SO2 etc. from stacks are often measured and reported for regulatory compliance purposes on a mass flow rate basis. Mass flow rates are typically calculated and reported in units of lbs or kg per hour and tons per year for these pollutants. The pollutant mass flow rate is a function of the pollutant concentration of the stack gas, the stack size & shape, and the stack gas velocity.
The Uniphos Integrated Temperature, Pressure and Flow Probe is meant for continuous and real time measurement of Temperature, Pressure and velocity of gases in industrial stacks. All the three sensors are integrated on a single flange and can easily be mounted on the stack without any hassle.
