  • Inferential coriolis mass flowmeter for determining a mass flowrate of a fluid by using algorithm derived partially from coriolis force
    Patent number: 9175995
    Abstract: An inferential Coriolis mass flowmeter characterized by: a power supply (10); a pressure sensor (11) connected to the power supply (10) and a tube of fluid; a current to voltage converter (13) connected to the pressure sensor (11) for converting a current signal from the pressure sensor (11) to a voltage signal; a controller unit (20) including an analogue to digital converter (21) connected to the current to voltage converter (13) for converting analogue signal from the current to voltage converter (13) to a digital signal, and a microprocessor (22) for processing the digital signal from the analogue to digital converter (21) to determine the mass flowrate of the fluid, wherein the microprocessor (22) is embedded with an algorithm to determine the mass flowrate of a fluid according to equation: y=0.002x4?0.0218x3?0.0865x2?0.8769x?0.0846; a display panel (14) connected to the microprocessor (22); and a transmission circuit (15) connected to the microprocessor (22).
