The Dirty Air Pitot (DAP) is a portable instrument designed to measure the flow-velocity, temperature and dynamic pressure in pipes or duct systems which pneumatically transport a mixture of air and particles such as pulverized coal or biomass, cement, lime or other particles of similar size.
The DAP can work as a stand-alone unit and provide data to the operator or alternatively in combination with the M&W PFS or PFSA to ensure optimal measurements.
The DAP is inserted into the pipe through a Dustless Connection (DuC). The DAP is outfitted with a distance indicator, which is needed in order to obtain data for the full flow-velocity profile of the pipe.
The data produced can be used independently or in combination with the M&W PFS or PFSA enabling isokinetic sampling of the fuel pipe.
When the DAP is inserted into the pipe, it is positioned all the way into the pipe, and slowly dragged out while performing the measurements. The DAP measures the pressure difference between the upstream and downstream face of the probe. The downstream pressure corresponds to the static pressure and the upstream pressure corresponds to the stagnation pressure of the flow. The difference between these pressures can be used to estimate the flow-velocity
By performing measurements across the full cross-section of the pipe, the full flow-velocity profile can be obtained. The DAP has distance indicators, which allow the operator to manually read the measurements.
