Features and Benefits:
- Optimize Burner Performance. The CA Station provides the accurate combustion airflow information needed to optimize stoichiometric Air to Fuel ratios and facilitate more complete, stable combustion.
- Optional Cleanouts. For applications with a high concentration of airborne particulate matter (fly ash, dust, etc.), the CA Station may be equipped with optional cleanouts. These consist of an extension of each sensing manifold through the casing wall, terminated in a female pipe fitting and removable plug, to permit internal manual cleanout of individual manifolds, without the need to turn off the fan/system, or to enter the duct.
- Optional Signal Extensions. Extensions are available as an option on the CA Station, for both signal connections, and cleanout fittings, in order to simplify the installation on insulated ducts.
- Optional Traverse Ports. For applications with less-than-ideal installation locations, the CA Station may be equipped with optional traverse ports, to enable field verification of flow conditions via a manual traverse.
- Optional Temperature Sensor. Temperature sensors in single point or, multi-point measurement, and local or remote Temperature Transmitter options are available.
- Log-Tchebycheff. A high concentration of total and static pressure sensors positioned according to the log-Tchebycheff rule sense the multiple and varying flow components that constitute the air stream’s velocity profile. The log-Tchebycheff’s perimeter weighted sensor pattern is utilized in rectangular ducts to minimize the positive error (measurements greater than actual) caused by the failure to account for slower velocities at the duct wall when using traditional equal area sensor locations. Since the static pressure across a measurement plane is uniform, fewer static pressure sensors are used to minimize unrecovered permanent pressure drop.
- Fechheimer Pitot Flow Measurement. The CA Station operates on the Fechheimer-Pitot derivative of the multi-point, self-averaging Pitot principle to measure the total and static pressure components of airflow. Total pressure sensing ports with patented (U.S. Patent No. 4,559,835) chamfered entrances, and Fechheimer pairs of offset static pressure sensing ports combine to minimize the effect of directional airflow. When located downstream of honeycomb airflow processing cell, the Fechheimer Pitot method is extremely effective at accurately measuring airflow in limited straight duct runs.
- Negligible Airflow Resistance. The CA Station airflow measuring station is designed to function while producing a minimum of resistance to airflow, due to the unique honeycomb air straightener-equalizer section having a free area of 96.6%.
- Configurations. Rectangular, Circular, and Custom.
