Test stand data table-based fluid flow device with remote calibration system and method

A method for calibrating a product variable aperture fluid flow valve disposed within a site duct, and defining a fluid flow path along a product flow axis though the site duct from an upstream end of the site duct to a downstream end of the site duct,

• wherein the product variable aperture fluid flow valve is characterized by a product structure characterized by a product geometric shape and a set of product operational parameters,
• wherein the product variable aperture fluid flow valve includes:
• (i) one or more product blades of a product damper assembly, a product actuator assembly, and an associated product blade controller, whereby the one or more product blades are movable by the product actuator assembly, to define a product orifice extending transverse to the product flow axis and through an array of one or more adjustably sized cross-section area product flow apertures, wherein, in aggregate, the product flow apertures are adjustable between a lower limit and an upper limit, and
• (ii) a product differential pressure sensor adapted to determine pressure drop across the one or more product blades, comprising the steps of:
• for a calibration variable aperture fluid flow valve remote from the product variable aperture fluid flow valve, and having a calibration damping assembly with a calibration structure characterized by a geometric shape and operational parameters corresponding to those of the product variable aperture fluid flow valve, including one or more calibration blades defining a variable aperture calibration orifice and an associated calibration actuator assembly, and disposed within a calibration duct characterized by a calibration duct geometry corresponding to that of the product duct, and
• A. with a calibration blade controller,
• a. establishing a plurality of calibration conditions with respect to the calibration variable aperture fluid flow valve, wherein the calibration conditions are representative of a set of calibration data pairs wherein each calibration data pair includes for at least one calibration condition:
• i. a pressure drop element corresponding to an associated pressure drop across the calibration variable aperture fluid flow valve, and
• ii. an aperture area element corresponding to an associated aggregate area of the apertures of the calibration variable aperture fluid flow valve,
• b. determining a calibration flow rate (CFM) function, associated with the set of calibration data pairs,
• B. transferring CFM data representative of the CFM function from the calibration blade controller to the product blade controller, and
• C. with the product blade controller and the product actuator assembly, in response to the received CFM data, and a determined pressure differential across the one or more product blades, and a received desired parameter control signal, adjusting the adjustably sized cross-section area product flow apertures over time so that a set point for a parameter is attained.
