THE CONSTRUCTION, TESTING AND DELIVERY OF A BALLISTIC FLOW PROVER SYSTEM.
Abstract
This report describes the general need and the resultant effort required to develop and manufacture an in-line flowmeter proving system, for the specific needs of the Rocket Propulsion Laboratory, Air Force Systems Command, United States Air Force, Edwards, California. Since the flowmeter prover has been developed and evaluated for conventional storable propellants, the specific program involved in the development of this system was to take existing 'Ballistic Flow Prover' concepts and techniques and apply them as a feasible approach toward solving the calibration problems involved using thixotropic and slurry type propellants. A 'Ballistic Flow Prover' was then designed to perform its function by allowing temporary freedom to a normally latched piston, within a fluid bypass chamber, which in turn moves a fixed distance downstream in perfect unison with the flowing propellant. The downstream motion of the freed piston is observed by three detectors at fixed positions which precisely delineate specific volumes of displaced propellant. The position detectors supply electrical pulses to an oscillographic recorder which is simultaneously recording the pulse output of the turbine flowmeter under observation and a precise time base signal. The recorded electrical pulses provide for the accurate verification of the observed flowmeter's performance even though the propellants viscosity characteristics vary as experienced with thixotropics and slurries.
