Development of a prototype compact fluidic-type gas meter. Final report, May 1988-November 1992
A compact gas meter has been designed to operate from 1.75 cfh to 175 cfh for use as a residential gas meter. The design is based on the trapped vortex pair fluidic oscillator principle. It has no moving parts to wear out. The maximum pressure drop is 1.0 inch of water column at 175 cfh. A battery powered electronics package has been developed by Alnor Instrument Co. to record the fluidic oscillations and display the flow rate and total volume of gas transferred through the meter. A microprocessor stores the calibration constants for the meter in order to account for the nonlinearity in the calibration. A thermistor in a constant temperature anemometer circuit is used to measure the flow rates below the 1.75 cfh lower limit of the fluidic oscillator.
