Claim 1
Independent Claim
127 words
A MASS FLOWMETER FOR MEASURING THE MASS FLOW RATE OF FLUID PASSING THERETHROUGH AT A VOLUMETRIC FLOW RATE, COMPRISING A CONDUIT HAVING A FLOW RESTRICTOR, MEANS FOR ADDING A SUPPLEMENTAL VOLUMETRIC FLOW RATE OF FLUID TO SAID VOLUMETRIC FLOW RATE PASSING THROUGH SAID FLOW RESTRICTOR, MEANS FOR REMOVING SAID SUPPLEMENTAL VOLUMETRIC FLOW RATE OF FLUID FROM SAID VOLUMETRIC FLOW RATE PASSING THROUGH SAID FLOW RESTRICTOR, MEANS FOR MEASURING THE MAXIMUM PRESSURE DIFFERENCE OCCURRING ACROSS SAID FLOW RESTRICTOR DURING THE ADDITION OF SAID SUPPLEMENTAL VOLUMETRIC FLOW RATE TO DERIVE A FIRST SIGNAL AND MEANS FOR MEASURING THE MAXIMUM PRESSURE DIFFERENCE OCCURRING ACROSS SAID RESTRICTOR DURING THE REMOVAL OF SID SUPPLEMENTAL VOLUMETRIC FLOW RATE TO DERIVE A SECOND SIGNAL, AND MEANS FOR ALGEBRAICALLY COMBINING SAID FIRST AND SECOND SIGNALS.
