Further development of a recirculating type wide range fuel flow meter is proposed, feasibility having been demonstrated in the phase I effort. It is proposed to modify the design of the recirculating type meter, a working model of which was produced under phase I, to reduce its size and simplify its construction. Electronic circuitry will be repackaged in a compact housing for panel mounting. A prototype of the modified design will be fabricated and calibrated against a primary standard to reconfirm accuracy of the design. Performance goals for the meter are to achieve a 1% or better measurement uncertainty over purpose of developing a highly produceable product, effort will be directed towards reducing the size of the meter, improving the reliability of the circulating pump and the possible use of an air driven pump. Testing to be performed in proof of the design will include calibrations of the main meter with and without recirculating flow, response to flow transients and the effect of supply pressure variations.
