ABSTRACT:
A rate of fluid flow measuring device utilizing a pair of helical Bourdon tubes to generate output signals, from two linear variable differential transformers, which are functions of fluid pressure and flow velocity. A thermocouple generates an output signal which is a function of the temperature of the fluid if a compressible fluid is to be measured. These pressure and temperature output signals are applied to computation means, programmed to solve a modified flow equation, as the variables in the equation, thereby generating an output signal which is a function of flow rate. The helical Bourdon tubes have inlet pressures applied to both ends thereof and are sealed at their centers, the seals being connected to the cores of the linear variable differential transformers to control the transformer output in accordance with the pressure drops across the seals.
