9. By-Pass Flow Meter for Sloped Pipelines

Accurate flow measurement has fiscal consequences and also necessitates fulfillment of stipulated requirement of upstream and downstream straight length at flow metering section. Many times, the site constraints do not permit to fulfill this requirement at metering sections. The present paper addresses to simulate an alternate by-pass flow meter to identify and measure the flow through the sloped pipelines of larger one for various flow rates. The alternate by-pass flow meter will be effectively useful in maintaining process accuracy by reducing downtime and improving the operational cycle of units at large. Based on the flow performance of the by-pass secondary pipes, the flow through the sloped pipe can be established by using the equation arrived by the standards flow simulation at site. The experiment reveals that by establishing by-pass arrangement, the head loss across the combined piping is minimized, The modified by-pass arrangement will be more useful for sloped pipes in terms of site constraints and operational difficulties encountered in the process industries.
