Linearity measures how linear the output signal is expected to be in proportion to flow…
Flow Meter Location
Use the following guidelines to determine the location of the flow meter:
• Field indicators, recorders and controller should be located adjacent to the process equipment of interest to the flow measurement and should be installed for easy operator viewing of the indicated or recorded flow value.
• Flow transmitters should be specified with integral output meters and located so that the output meter is visible from the related control valve or drive. Where such orientation is not practical, a remote output meter should be installed adjacent to the related control valve or drive.
• In an integrated operating facility, plot limit field indicators and recorders should be located adjacent to major process and utility plot-limit manifolds, away from areas of high fire or corrosive potential. One of the vital uses of the flow information displayed on these meters is to verify the function of emergency block valves and utility stream supply to plants during major plant upsets or mishaps.
