Abstract:
A flowmeter that provides a flowmeter output indicative of a mass flow rate of a fluid as a function of a measured fluid temperature or a measured fluid pressure, the flowmeter comprising:a flowtube; a first sensor disposed in the flowtube having a volumetric output that varies as a function of a volumetric flow rate of the fluid; a second sensor positioned at a first location in the flowtube to measure a parameter of the fluid at the first location; a circuit receiving a parameter value from the second sensor and the volumetric output from the first sensor, the circuit providing the flowmeter output as a function of the parameter value and the volumetric output; and wherein the circuit is further configured to apply a correction to the parameter value and to yield an adjusted value representative of the parameter of the fluid at a second location, the adjusted value being used by the circuit to calculate the flowmeter output.
