Abstract: The disclosure generally relates to flow meters and more particularly relates to systems and methods for determining, among other things, mass flow measurements of fluids. In certain embodiments, a system may include a pipe having a fluid flow therethrough, a first flow meter coupled to the pipe, and a second flow meter coupled to the pipe in series with the first flow meter. The system also may include a computer in communication with the first flow meter and the second flow meter. The computer may be configured to receive fluid flow information from the first flow meter; receive fluid flow information from the second flow meter; and determine, based at least in part on the fluid flow information from the first flow meter and the fluid flow information from the second flow meter, a mass flow measurement of the fluid flow.

Abstract: Certain embodiments of the invention may include systems, methods, and apparatus for providing compensating atmospheric pressure measurements in fired equipment. According to an example embodiment of the invention, a method is provided compensating pressure measurements. The method includes providing a wind compensating ring tube having three or more apertures to equalize pressure inside the compensating ring tube, installing the wind compensating ring tube adjacent to a furnace, connecting a pressure transmission tube from the wind compensating ring tube to one or more pressure sensors, and transmitting pressure from inside the wind compensating ring tube to the one or more pressure sensors by the pressure transmission tube.

Abstract: Certain embodiments of the invention may include systems, methods, and apparatus for determining airflow through a burner. According to an example embodiment of the invention, a method is provided for determining airflow through a burner. The method includes installing a first end of an inlet pressure transmission tube in an air inlet region of a furnace burner system, installing a first end of a burner pressure transmission tube in a burner exit region of the furnace burner system, connecting a second end of the inlet pressure transmission tube to a first pressure sensor, connecting a second end of the burner pressure transmission tube to a second pressure sensor, measuring the differential pressure between the first and second pressure sensors, and determining airflow based at least in part on the measured differential pressure.
