FUNCTION & CONTROL METHOD
Coriolis, ultrasonic, vortex, magnetic, turbine, positive-displacement or differential-pressure technology is selected by fluid, conductivity, viscosity, range, pressure loss and accuracy.
ELECTRICAL, INSTRUMENTATION & AUTOMATION
Flow Instrumentation
Measures and controls liquid, gas, steam and multiphase-compatible services for process control, balance and metering.
MAIN HARDWARE & SYSTEM BOUNDARY
Flowmeters, primary elements, meter runs, flow computers, pressure/temperature compensation, straightening devices, samplers and isolation/bypass arrangements.
CRITICAL DESIGN INPUTS
Approved P&IDs and control philosophy, process ranges and alarm/trip limits, hazardous-area classification, environmental conditions, I/O and load lists, availability/redundancy target, package interfaces, communication protocols, cybersecurity and client standards.
ENGINEERING DELIVERABLES
System architecture, instrument/equipment index, datasheets, I/O list, hook-ups, loop and wiring diagrams, cabinet/panel drawings, cable schedule, network drawings, control narratives, cause-and-effect, logic diagrams, graphics, test procedures and as-built backups.
FUNCTIONAL SAFETY, RELIABILITY & CYBERSECURITY
Meter diagnostics, grounding, empty-pipe or low-flow alarms, legal-metrology sealing where applicable and independent shutdown flow signals are defined.
TESTING, COMMISSIONING & APPLICATIONS
Feed/product flow, steam, fuel gas, cooling water, chemicals, loading and custody transfer. Wet calibration or traceable verification is specified.
