CEMFlow offers ultimate reliability and maintainability for measuring gas flow in a stack or duct. Pitot tube gas flow monitoring systems provide the lowest installation and maintenance costs of any flow system on the market today.

For Compliance Stack Flow Monitoring, a simple pitot tube flow sensor is utilized in situ to measure differential pressure as gas flows up a stack or through a duct. High and low pressure is measured, then utilized to calculate stack velocity (using the Bernoulli equation). Multiplying by the stack/duct diameter converts this velocity to flow.
