LIQUID MEASUREMENT STATION DESIGN Class # 2230

摘要

There are many factors that must be considered to properly design a liquid measurement station.While many of the components of measurement stations are similar,the criterion that determines the equipment to utilize for a given application or product can vary significantly from project to project.This paper will address the most common applications in the liquid hydrocarbon industry for large volume product measurement as it pertains to custody transfer applications.Custody transfer measurement includes accurate quantity measurement using metering,though equally important is accurate quality measurement through the use of quality and sampling equipment.These custody transfer and/or fiscal metering stations consist of mechanical components and instrumentation on a skidded system along with simple to complex supervisory control systems with flow computers,programmable logic controllers(PLCs) and a human machine interface(HMI) with customized programming to achieve the required measurement goal.
