Some immediate savings with FF – user’s comments.

Device Configuration:

Configuration of field devices is easier – the system automatically senses the device when it is connected.

With 1200 devices, the savings during commissioning is about $50,000

Magnetic Flow Meters

•Empty pipe•Detect if no liquid in flowtube (avoid false reading)

•Grounding•Check for improper grounding (connection corrosion)

•Process noise•Smart meter verification

•Assess need for calibration

© 1999 – 2010 Fi eldbus Foundation14

• Magnetic Flow Meters: •disruptive and time consuming maintenance procedures are eliminated with FF enhanced diagnostics;• Noise amplitude measurement • Lost of grounding Detection•Tunable empty pipe diagnostics to prevent false triggering•Smart Meter Verification can be triggered from maintenance station. •NO DOWNTIME ON MAGFLOWS!

pH Analyzers

•pH/ORP measurements•Advanced diagnostics

•Glass impedance•Reference impedance•Slope•Offset

•Applications: eliminate lab sampling

•Final effluent•Raw waters•Treatment tanks•RO raw water: protect membranes

Savings on Project Execution

• Startup and Commissioning•Advance diagnostics•live list detection•self-addressing

© 1999 – 2010 Fi eldbus Foundation22

Savings on Project Execution

Non critical loops and monitoring will maximize the bus capacity (up to 16 field devices per segment).

Reduced wiring costs :

Using FF, a communication cable can combine signals from multiple devices on fieldbus segments using a trunk and spur technology, thus greatly reducing the wiring and conduit requirements.

• Less maintenance due to lower number of field devices•Control in the Field + LAS – prevent from unwanted shutdown.• Lower maintenance costs (Asset Management) – Proactive Maintenance. Device informs the System when maintenance is needed.•Increase the control quality on blowers, chemical feed pumps, temperature control on thermal hydrolysis, etc.•More information to the Control Room

Long Term Savings
