Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
139 words
APPARATUS FOR MEASURING THE MASS FLOW OF A DIELECTRIC MATERIAL THROUGH A FLOW CONDUIT, COMPRISING A BY-PASS CONDUIT AROUND A PORTION OF SAID FLOW CONDUIT; A PAIR OF ELECTRODES MOUNTED IN SAID BY-PASS CONDUIT, SAID ELECTRODES BEING SPACED IN THE DIRECTION OF FLUID FLOW THERETHROUGH AND SHAPED TO PROVIDE A NON-UNIFORM ELECTRIC FIELD THEREIN; A POWER SUPPLY HAVING ADJUSTING MEANS FOR APPLYING A VARIABLE VOLTAGE ACROSS SAID ELECTRODES TO PROVIDE A VARIABLE FORCE ON SAID DIELECTRIC MATERIAL TO COUNTERACT THE MASS FLOW THEREOF THROUGH THE SAID BY-PASS CONDUIT, MEANS POSITIONED IN SAID BY-PASS CONDUIT AND RESPONSIVE TO MOVEMENT OF SAID MATERIAL THROUGH SAID BY-PASS CONDUIT FOR REGULATING SAID POWER SUPPLY VOLTAGE ADJUSTING MEANS TO NULL SAID MATERIAL MOVEMENT, AND MEANS RESPONSIVE TO THE ADJUSTED VALUE OF SAID POWER SUPPLY VOLTAGE FOR QUANTITATIVELY INDICATING SAID FLOW IN SAID FLOW CONDUIT.
