ABSTRACT:
Presented is a fluid property measuring device which can be used to measure he viscosity, the density, the volumetric flow rate, and the mass flow rate, of a fluid without using moving parts. The fluid property measuring device comprises a linear fluid resistor, a nonlinear resistor, and a linear, fluid property independent, volumetric flowmeter, Two nonlinear resistors, or two linear resistors, may be used instead of a linear and nonlinear resistor. The linear, fluid property independent, volumetric flowmeter comprises a fluidic negative feedback oscillator in fluid connection with a fluidic buffer laminar proportional amplifier.
