Topic: Purge FLOW vs. PRESSURE: the real costs

Instrument purge is critical in any system where process measurements (pressure, level, or flow) are required, but direct contact between the process medium and instrumentation is not acceptable.

The purge is only required as act as a pressure barrier between the process and field instrument, and any positive flow should be reduced to an absolute minimum to ensure efficient production.

This session will discuss the real costs associated with using purge FLOW instead of PRESSURE, and an alternative solution to ensure safe, reliable, efficient process variable measurement systems.
