A FLOW METER MODULE FOR A CONTROLLER

摘要

A method and apparatus for utilizing a controller to monitor a flow volume in a fluid transportation system is disclosed. The controller being operably connected to a module. The module being operably connected to a flow meter. The modules senses a series of pulses that represent a known fluid volume in a proving loop. The module also measures the fluid density of the fluid in the proving loop. The controller utilizes a dynamic density of the fluid and the sensed pulses to determine a correction factor to more accurately calculate the flow volume through the measuring flow meter. The controller ensures the accuracy of the flow meter by utilizing the partial pulses sensed during a meter proving period by using an interpolation method.
