Method of and apparatus for measuring varying fluid flow
Abstract
Abstract A DUAL METER LINE HAVING A FLUID FLOW COMPUTER AND SWITCHOVER CONTROLS IN WHICH THE MEASUREMENT SYSTEM IN RESPONSE TO FLOW RATES AUTOMATICALLY DIRECTS THE FLOW OF FLUIDS TO BE MEASURED THROUGH A LOW OR HIGH RATE METER LINE METERING ORIFICE WHERE THE FLOW PARAMETERS ARE MEASURED AND MONITORED BY THE COMPUTER WHICH COMPUTES THE FLUID VOLUME. FIRST AND SECOND METERING LINES, CONNECTED TO A PIPELINE HAVING DIFFERENT SIZED MEASURING ORIFICES THEREIN WHEREIN THE FLUID FLOW IS DIRECTED TO ONE OF THE METERING LINES WHEN THE FLOW RATE IS BELOW A PREDETERMINED AMOUNT, AND A MEASUREMENT SYSTEM MEASURES THE FLUID FLOW VARIABLES IN SAID ONE LINE AND A FLOW COMPUTER COMPUTES THE FLUID VOLUME, AND WHEN THE FLOW RATE INCREASES ABOVE A PREDETERMINED AMOUNT THE FLUID IS SWITCHED TO THE SECOND METERING LINE AND THE FLOW VARIABLES ARE MEASURED ACROSS THE SECOND ORIFICE, THE FLOW MEASUREMENTS TRANSMITTED TO THE FLOW COMPUTER IN WHICH THE COUNTER SCALE IS AUTOMATICALLY CHANGED TO CORRELATE WITH THE SIZE OF THE ORIFICE IN THE SECOND LINE.
