CEMFlowTM S-Type pitot tube Compliance Stack Flow Monitoring systems offer the ultimate in reliability and maintainability for measuring gas flow in a stack or duct. Pitot tube gas flow monitoring systems offer 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 insitu to measure differential pressure as gas flows up a stack. High and low pressure is measured, then utilized to calculate stack velocity (using the Bernoulli equation). Multiplying by the stack diameter converts this velocity to flow.
This technology is capable of accurately measuring gas flow from ~5 to 900 ft./sec, at temperatures up to 1800oF. CEMFlowTM sensors utilize a variety of designs and materials (appropriate metallurgy/ceramic, etc.) to accommodate a large number of flow applications.
